* gfapi: glfs_set_volfile_server() now entertains multiple callsHarshavardhana2014-04-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Previous API: glfs_set_volfile_server (..., const char *host, ...) - single call New API's: glfs_set_volfile_server (..., const char *host1, ...) glfs_set_volfile_server (..., const char *host2, ...) Multiple calls to this function with different volfile servers, port or transport-type would create a list of volfile servers which would be polled during `volfile_fetch_attempts()` glfs_unset_volfile_server (..., const char *host, ...) to remove a server from the list (this is provided for future usage) Change-Id: I313efbd3efbd0214e2a71465f33195788df406cc BUG: 986429 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/7317 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>
* log: enhance gluster log format with message ID and standardize errno reportingShyamsundarR2014-03-2811-329/+1242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are quite a slew of logs in Gluster that do not lend themselves to trivial analysis by various tools that help collect and monitor logs, due to the textual nature of the logs. This FEAT is to make this better by giving logs message IDs so that the tools do not have to do complex log parsing to break it down to problem areas and suggest troubleshooting options. With this patch, a new set of logging APIs are introduced that take additionally a message ID and an error number, so as to print the message ID and the descriptive string for the error. New APIs: - gf_msg, gf_msg_debug/trace, gf_msg_nomem, gf_msg_callingfn These APIs follow the functionality of the previous gf_log* counterparts, and hence are 1:1 replacements, with the delta that, gf_msg, gf_msg_callingfn take additional parameters as specified above. Defining the log messages: Each invocation of gf_msg/gf_msg_callingfn, should provide an ID and an errnum (if available). Towards this, a common message id file is provided, which contains defines to various messages and their respective strings. As other messages are changed to the new infrastructure APIs, it is intended that this file is edited to add these messages as well. Framework enhanced: The logging framework is also enhanced to be able to support different logging backends in the future. Hence new configuration options for logging framework and logging formats are introduced. Backward compatibility: Currently the framework supports logging in the traditional format, with the inclusion of an error string based on the errnum passed in. Hence the shift to these new APIs would retain the log file names, locations, and format with the exception of an additional error string where applicable. Testing done: Tested the new APIs with different messages in normal code paths Tested with configurations set to gluster logs (syslog pending) Tested nomem variants, inducing the message in normal code paths Tested ident generation for normal code paths (other paths pending) Tested with sample gfapi program for gfapi messages Test code is stripped from the commit Pending work (not to be addressed in this patch (future)): - Logging framework should be configurable - Logging format should be configurable - Once all messages move to the new APIs deprecate/delete older APIs to prevent misuse/abuse using the same - Repeated log messages should be suppressed (as a configurable option) - Logging framework assumes that only one init is possible, but there is no protection around the same (in existing code) - gf_log_fini is not invoked anywhere and does very little cleanup (in existing code) - DOxygen comments to message id headers for each message Change-Id: Ia043fda99a1c6cf7817517ef9e279bfcf35dcc24 BUG: 1075611 Signed-off-by: ShyamsundarR <srangana@redhat.com> Reviewed-on: http://review.gluster.org/6547 Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | cluster op-version must be atleast 4 for add/remove brick to proceed. This change is required for the new afr-changelog xattr changes that will be done for glusterFS 3.6 (http://review.gluster.org/#/c/7155/). In add-brick, the check is done only when replica count is increased because only that will affect the AFR xattrs. In remove-brick, the check is unconditional failing which there will be inconsistencies in the client xlator names amongst the volfiles of different peers.

| | | | | | | | | | | | | | | | | | | Currently any logs that are logged after calling glfs_fini will appear on stderr. Ideally to the end of the glfs_fini all the operations will be complete and there should be no further logging. But it appears that the client translator is still up and prints some log messages even after calling glfs_fini. In this patch the log level is set to GF_LOG_NONE once the log file is closed. This fix is not required if wait for "CHILD_DOWN" event is implemented in glfs_fini.

* protocol/server: do not do root-squashing for trusted clientsRaghavendra Bhat2014-02-103-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Sengupta2014-02-102-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This may not always be executed in same thread which executed [SYNCOP-1]) if (ret < 0) { if (errno != ENODATA) { loglevel = GF_LOG_ERROR; defrag->total_failures += 1; ..... } the function above could be executed by thread(t1) till [SYNCOP-1] and code from [ERRNO-2] can be executed by a different thread(t2) because of the way syncop-infra schedules the tasks. when the code is compiled with -O2 optimization this is the assembly code that is generated: [ERRNO-1] 1165 readdir_operrno = errno; <<---- errno gets expanded as *(__errno_location()) 0x00007fd149d48b60 <+496>: callq 0x7fd149d410c0 <address@hidden> 0x00007fd149d48b72 <+514>: mov %rax,0x50(%rsp) <<------ Address returned by __errno_location() is stored in a special location in stack for later use. 0x00007fd149d48b77 <+519>: mov (%rax),%eax 0x00007fd149d48b79 <+521>: mov %eax,0x78(%rsp) ....

So [ERRNO-2] ends up reading errno of t1 instead of errno of t2 even though t2 is executing [ERRNO-2] code section. When code is compiled without any optimization for [ERRNO-2]: 1281 if (errno != ENODATA) { 0x00007fd58e7a326f <+2237>: callq 0x7fd58e797300 <address@hidden><<--- As it is calling __errno_location() again it gets the location from t2 so it works as intended. 0x00007fd58e7a3274 <+2242>: mov (%rax),%eax 0x00007fd58e7a3276 <+2244>: cmp $0x3d,%eax 0x00007fd58e7a3279 <+2247>: je 0x7fd58e7a32a1 <gf_defrag_migrate_data+2287> Fix: Make syncop_xxx() return (-errno) value as the return value in case of errors and all the functions which make syncop_xxx() will need to use (-ret) to figure out the reason for failure in case of syncop_xxx() failures.

* 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.

Problem: After disabling and then enabling quota back, the xattrs may contain stale data leading to impaired accounting and thus improper enforcement. Solution: Clean up all the quota related xattrs after quota disable. Marker xlator implements a virtual xattr to cleanup quota and pgfid xattrs. In this approach glusterd mounts an auxiliary mount and sends the below command to all the files by crawling the mountpoint. #setfattr -n "glusterfs.quota-xattr-cleanup" -v 1 <path/to/file> Credit: Krishnan Parthasarathi <kparthas@redhat.com> Varun Shastry <vshastry@redhat.com> Change-Id: I9380eca58a285dc27dd572de1767aac8f2cd8049 BUG: 969461 Signed-off-by: Varun Shastry <vshastry@redhat.com> Reviewed-on: http://review.gluster.org/6369 Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* features/quota: Improvements to quotaRaghavendra G2013-11-269-6/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* posix: placeholders for GFID to path conversionRaghavendra G2013-11-261-0/+4

To find the path of a directory, the symlink handle to the directory maintained in the ".glusterfs" backend directory is read. The symlink handle is generated using the gfid of the directory. It (handle) contains the directory's name and parent gfid, which are used to recursively construct the absolute path as seen by the user from the mount point. A similar approach cannot be used for a regular file or a symbolic link since its hardlink handle, generated using its gfid, doesn't contain its parent gfid and basename. So xattrs are set to store the parent gfids and the number of hardlinks to a file or a symlink having the same parent gfid. When an user/application requests for the paths of a regular file or a symlink with multiple hardlinks, using the parent gfids stored in the xattrs, the paths of the parent directories are generated as mentioned earlier. The base names of the hardlinks (with the same parent gfid) are determined by matching the actual backend inode numbers of each entry in the parent directory with that of the hardlink handle. Xattr is set on a regular file, link, and symbolic link as follows, Xattr name : trusted.pgfid.<pargfidstr> Xattr value : <number of hardlinks to a regular file/symlink with the same parentgfid> If a regular file, hard link, symbolic link is created then an xattr in the above format is set in the backend. how to use? =========== This functionality can be used through getxattr interface. Two keys - glusterfs.ancestry.dentry and glusterfs.ancestry.path - enable usage of this functionality. A successful getxattr will have the result stored under same keys. Values will be, glusterfs.ancestry.dentry: -------------------------- A linked list of gf-dirent structures for all possible paths from root to this gfid. If there are multiple paths, the linked-list will be a series of paths one after another. Each path will be a series of dentries representing all components of the path. This key is primarily for internal usage within glusterfs. glusterfs.ancestry.path: ------------------------ A string containing all possible paths from root to this gfid. Multiple hardlinks of a file or a symlink are displayed as a colon seperated list (this could interfere with path components containing ':'). e.g. If there is a file "file1" in root directory with two hardlinks, "/dir2/link2tofile1" and "/dir1/link1tofile1", then [root@alpha gfsmntpt]# getfattr -n glusterfs.ancestry.path -e text file1 glusterfs.ancestry.path="/file1:/dir2/link2tofile1:/dir1/link1tofile1" Thanks Amar, Avati and Venky for the inputs.
