* rpcsvc: Ignore INODELK/ENTRYLK/LK for throttlingPranith Kumar K2014-04-241-16/+54
| | | | | | | | | | | | | | | | | | | | | | Problem: When iozone is in progress, number of blocking inodelks sometimes becomes greater than the threshold number of rpc requests allowed for that client (RPCSVC_DEFAULT_OUTSTANDING_RPC_LIMIT). Subsequent requests from that client will not be read until all the outstanding requests are processed and replied to. But because no more requests are read from that client, unlocks on the already granted locks will never come thus the number of outstanding requests would never come down. This leads to a ping-timeout on the client. Fix: Do not account INODELK/ENTRYLK/LK for throttling Change-Id: I59c6b54e7ec24ed7375ff977e817a9cb73469806 BUG: 1089470 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/7531 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>

* rpc: warn and truncate grouplist if RPC/AUTH can not hold everythingNiels de Vos2014-04-083-8/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GlusterFS protocol currently uses AUTH_GLUSTERFS_V2 in the RPC/AUTH header. This header contains the uid, gid and auxiliary groups of the user/process that accesses the Gluster Volume. The AUTH_GLUSTERFS_V2 structure allows up to 65535 auxiliary groups to be passed on. Unfortunately, the RPC/AUTH header is limited to 400 bytes by the RPC specification: http://tools.ietf.org/html/rfc5531#section-8.2 In order to not cause complete failures on the client-side when trying to encode a AUTH_GLUSTERFS_V2 that would result in more than 400 bytes, we can calculate the expected size of the other elements: 1 | pid 1 | uid 1 | gid 1 | groups_len XX | groups_val (GF_MAX_AUX_GROUPS=65535) 1 | lk_owner_len YY | lk_owner_val (GF_MAX_LOCK_OWNER_LEN=1024) ----+------------------------------------------- 5 | total xdr-units one XDR-unit is defined as BYTES_PER_XDR_UNIT = 4 bytes MAX_AUTH_BYTES = 400 is the maximum, this is 100 xdr-units. XX + YY can be 95 to fill the 100 xdr-units. Note that the on-wire protocol has tighter requirements than the internal structures. It is possible for xlators to use more groups and a bigger lk_owner than that can be sent by a GlusterFS-client. This change prevents overflows when allocating the RPC/AUTH header. Two new macros are introduced to calculate the number of groups that fit in the RPC/AUTH header, when taking the size of the lk_owner in account. In case the list of groups exceeds the maximum possible, only the first groups are passed over the RPC/GlusterFS protocol to the bricks. A warning is added to the logs, so that most system administrators will get informed. The reducing of the number of groups is not a new inventions. The RPC/AUTH header (AUTH_SYS or AUTH_UNIX) that NFS uses has a limit of 16 groups. Most, if not all, NFS-clients will reduce any bigger number of groups to 16. (nfs.server-aux-gids can be used to workaround the limit of 16 groups, but the Gluster NFS-server will be limited to a maximum of 93 groups, or fewer in case the lk_owner structure contains more items.)

* protocol/server: do not do root-squashing for trusted clientsRaghavendra Bhat2014-02-102-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * As of now clients mounting within the storage pool using that machine's ip/hostname are trusted clients (i.e clients local to the glusterd). * Be careful when the request itself comes in as nfsnobody (ex: posix tests). So move the squashing part to protocol/server when it creates a new frame for the request, instead of auth part of rpc layer. * For nfs servers do root-squashing without checking if it is trusted client, as all the nfs servers would be running within the storage pool, hence will be trusted clients for the bricks. * Provide one more option for mounting which actually says root-squash should/should not happen. This value is given priority only for the trusted clients. For non trusted clients, the volume option takes the priority. But for trusted clients if root-squash should not happen, then they have to be mounted with root-squash=no option. (This is done because by default blocking root-squashing for the trusted clients will cause problems for smb and UFO clients for which the requests have to be squashed if the option is enabled). * For geo-replication and defrag clients do not do root-squashing. * Introduce a new option in open-behind for doing read after successful open.

* glusterd: Volume locks and transaction specific opinfosAvra Sengupta2014-02-101-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch we are replacing the existing cluster-wide lock taken on glusterds across the cluster, with volume locks which are also taken on glusterds across the cluster, but are volume specific. So with the volume locks we are able to perform more than one gluster operation at the same time, as long as the operations are being performed on different volumes. We maintain a global list of volume-locks (using a dict for a list) where the key is the volume name, and which saves the uuid of the originator glusterd. These locks are held and released per volume transaction. In order to acheive multiple gluster operations occuring at the same time, we also separate opinfos in the op-state-machine, as a part of this patch. To do so, we generate a unique transaction-id (uuid) per gluster transaction. An opinfo is then associated with this transaction id, which is used throughout the transaction. We maintain a run-time global list(using a dict) of transaction-ids, and their respective opinfos to achieve this.

* build: Start using library versioning for various librariesHarshavardhana2014-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to libtool three individual numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The libtool script typically tacks these three numbers onto the end of the name of the .so file it creates. The formula for calculating the file numbers on Linux and Solaris is /path/to/library/<library_name>.(C - A).(A).(R) As you release new versions of your library, you will update the library's C:R:A. Although the rules for changing these version numbers can quickly become confusing, a few simple tips should help keep you on track. The libtool documentation goes into greater depth. In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number. This is called your interface number. The main use of this interface number is to tag successive revisions of your API. The AGE number is how many consecutive versions of the API the current implementation supports. Thus if the CURRENT library API is the sixth published version of the interface and it is also binary compatible with the fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When you break binary compatibility, you need to set AGE to 0 and of course increment CURRENT. The REVISION marks a change in the source code of the library that doesn't affect the interface-for example, a minor bug fix. Anytime you increment CURRENT, you should set REVISION back to 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Two stages of quota enforcement is done: Soft and hard quota Upon reaching soft quota limit on the directory it logs/alerts in the quota daemon log (ie DEFAULT_LOG_DIR/quotad.log) and no more writes allowed after hard quota limit. After reaching the soft-limit the daemon alerts the user/admin repeatively for every 'alert-time', which is configurable. * Quota enforcer is moved to server-side. It takes care of enforcing quota. Since enforcer doesn't have the cluster view, it relies on another service called quota-aggregator. Aggregator, on query can return the size of a directory based on the cluster view. Enforcer is always loaded in the server graph and is by passed if the feature is not enabled. Options specific to enforcer: server-quota - Specifies whether the feature is on/off. It is used to by pass the quota if turned off. deem-statfs - If set to on, it takes quota limits into consideration while estimating fs size. (df command). The algorithm followed is, i. Adjust statvfs based on limit configured on root. ii. If limit is set on the inode passed, use size/limits on that inode to populate statvfs. Otherwise, use size/limits configured on root. iii. Upon statvfs, update the ctx->size on the inode. iv. Don't let DHT aggregate, instead take the maximum of the usages from the subvols of the DHT, since each of it contains the complete information. Enforcer also makes use of gfid-to-path conversion functionality to work correctly when a client like nfs predominently relies on nameless lookups. * Quota Aggregator acts as a thin client to provide cluster view Its a lightweight *gluster client* process with no mount point, started upon enabling quota or restarting the volume. This is a single process run on each brick, which can answer queries on all volumes in the cluster. Its volfile stored in GLUSTERD_DEFAULT_WORKING_DIR/quotad/quotad.vol.

* glusterfs: zerofill supportM. Mohan Kumar2013-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for a new ZEROFILL fop. Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes. [root@llmvm02 remote]# time ./offloaded aakash-test log 20 real 3m34.155s user 0m0.018s sys 0m0.040s [root@llmvm02 remote]# time ./manually aakash-test log 20 real 4m23.043s user 0m2.197s sys 0m14.457s [root@llmvm02 remote]# time ./offloaded aakash-test log 25; real 4m28.363s user 0m0.021s sys 0m0.025s [root@llmvm02 remote]# time ./manually aakash-test log 25 real 5m34.278s user 0m2.957s sys 0m18.808s The argument log is a file which we want to set for logging purpose and the third argument is size in GB . As we can see there is a performance improvement of around 20% with this fop.

* libglusterfs: Add monotonic clocking counter for timer threadHarshavardhana2013-10-151-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gettimeofday() returns the current wall clock time and timezone. Using these functions in order to measure the passage of time (how long an operation took) therefore seems like a no-brainer. This time suffer's from some limitations: a. They have a low resolution: “High-performance” timing by definition, requires clock resolutions into the microseconds or better. b. They can jump forwards and backwards in time: Computer clocks all tick at slightly different rates, which causes the time to drift. Most systems have NTP enabled which periodically adjusts the system clock to keep them in sync with “actual” time. The adjustment can cause the clock to suddenly jump forward (artificially inflating your timing numbers) or jump backwards (causing your timing calculations to go negative or hugely positive). In such cases timer thread could go into an infinite loop. From 'man gettimeofday': ---------- .. .. The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2). .. .. ---------- Rationale: For calculating interval timing for Timer thread, all that’s needed should be clock as a simple counter that increments at a stable rate. This is necessary to avoid the jumps which are caused by using "wall time", this counter must be monotonic that can never “tick” backwards, ever.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently to know the number of files to be healed, either user has to go to backend and check the number of entries present in indices/xattrop directory. But if a volume consists of large number of bricks, going to each backend and counting the number of entries is a time-taking task. Otherwise user can give gluster volume heal vol-name info command but with this approach if no. of entries are very hugh in the indices/ xattrop directory, it will comsume time. So as a feature, new command is implemented. Command 1: gluster volume heal vn statistics heal-count This command will get the number of entries present in every brick of a volume. The output displays only entries count. Command 2: gluster volume heal vn statistics heal-count replica 192.168.122.1:/home/user/brickname Here if we are concerned with just one replica. So providing any one of the brick of a replica will get the number of entries to be healed for that replica only. Example: Replicate volume with replica count 2. Backend status: -------------- [root@dhcp-0-17 xattrop]# ls -lia | wc -l 1918 NOTE: Out of 1918, 2 entries are <xattrop-gfid> dummy entries so actual no. of entries to be healed are 1916.

XFS (potentially others?) doesn't understand when the 0x10 prefix is added to the ACL type field for default ACLs (which the Linux NFS client adds) which causes setfacl()->setxattr() to fail silently. NFS client adds NFS_ACL_DEFAULT(0x1000) for default ACL. FIX: Mask the prefix (added by NFS client) OFF, so the setfacl is not rejected when it hits the FS.

* Revert "glusterd: Fix spurious wakeups in glusterd syncops"Krishnan Parthasarathi2013-05-042-38/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit efa154bb0a4cac34d5a9610ec25d38eebe495f22. -- Following is Avati's analysis (edited) from gerrit -- The claim of the patch (being reverted) is that it in some cases cbkfn is missed. This is wrong analysis. cbk_fn is _always_ called. The patch treats ret > 0 as a "missed cbk". ret > 0 only means socket submission was not complete, and is queued to submit asynchronously when POLLOUT is raised. This is sufficient to guarantee that cbkfn is going to be called (either the socket errors or submission succeeds and reply eventually arrives). This commit also removes spurious barrier_wake(s). call backs are guaranteed to be called even if the transport is disconnected. This means, a 'wake' would be called if rpc_clnt_submit is called. Also, we count both successful and failed operations in a particular batch of operations for the synctask_barrier_wait. So, calling synctask_barrier_wake on failure of rpc_clnt_submit (say, due to network failure) would result in a spurious wake.

* glusterd: Fixed spurious wakeups in glusterd syncopsKrishnan Parthasarathi2013-04-122-7/+38
| | | | | | | | | | | | | glusterd syncops perform a barrier_wake whenever rpc_clnt_submit returned -1. This is based on the wrong assumption that the cbkfn wasn't called. This would result in one more wakeup than there ought to be.

| | | | | | | | | | | | | | | | | | Problem: For every gluster cli operation from command line rpc init process is required. During init process we print "no transport type set, defaulting to socket" message at WARNING level, which is not necessary. Solution: Moved the log level to DEBUG.

* rpc: before freeing the volume options object, delete it from the listRaghavendra Bhat2013-03-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | * Suppose there is an xlator option which is considered by the xlator only if the source was built with debug mode enabled (the only example in the current code base is run-with-valgrind option for glusterd), then giving that option would make the process crash if the source was not built with debug mode enabled. Reason: In rpc, after getting the options symbol dynamically, it was stored in the newly allocated volume options structure and the structure's list head was added to the xlator's volume_options list. But while freeing the structure the list was not deleted. Thus when the list was traversed, already freed structure was accessed leading to segfault.
