* DHT/readdirp: Directory not shown/healed on mount point if existsSusant Palai2014-06-163-5/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | on single brick(non first up subvolume). Problem: If snapshot is taken, when mkdir has succeeded only on hashed_subvolume, then after restoring snapshot the directory is not shown on mount point. Why: dht_readdirp takes only those directory entries in to account, which are present on first_up_subvolume. Hence, if the "hashed subvolume" is not same as first_up_subvolume, it wont be listed on mount point and also not healed. Solution: Case 1: (Rebalance not running)If hashed subvolume is NULL or down then filter in first_up_subvolume. Other wise the corresponding hashed subvolume will take care of the directory entry. Case 2: If readdirp_optimize option is turned on then read from first_up_subvol Change-Id: Idaad28f1c9f688dbfb1a8a3ab8b244510c02365e BUG: 1092433 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: http://review.gluster.org/7599 Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* dht/rebalance: Do not allow rebalance when gfid mismatch foundVenkatesh Somyajulu2014-06-141-1/+17
| | | | | | | | | | | | | | | | | | | | | Due to race condition, it may so happen that, gfid obtained in readdirp and gfid found by lookup are different for a given name. in that case do no allow the rebalance. Readdirp of an entry will bring the gfid, which will be stored in the inode through inode_link, and when lookup is done and gfid brought by lookup is different from the one stored in the inode, client3_3_lookup_cbk will return ESATLE and error will be captured by rebalance process.

* Rebalance: Avoid setting other component's xattrsSusant Palai2014-06-081-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem 1: In "gf_defrag_handle_hardlink" we used to do setxattr on internal afr keys. Which lead to afr aborting the op saying "operation not supported". Solution : Sending a new xattr with only required keys. Problem 2: Hardlink migration tries to create linkto files for 2nd to (n-1)th hardlink of a file on their respective hashed_subvolumes. It may so happen that the linkto file already exists on the hashed subvolume may be due to an earlier lookup or hashed subvolume on the older graph is same as that on the new graph. Hence any new link call may fail with EEXIST. Solution: Will log the message with DEBUG level for EEXIST . Otherwise will log with ERROR level.

* cluster/dht: Fix min-free-disk calculations when quota-deem-statfs is onKrutika Dhananjay2014-06-021-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: As part of file creation, DHT sends a statfs call to all of its sub-volumes and expects in return the local space consumption and availability on each one of them. This information is used by DHT to ensure that atleast min-free-disk amount of space is left on each sub-volume in the event that there ARE other sub-volumes with more space available. But when quota-deem-statfs is enabled, quota xlator on every brick unwinds the statfs call with volume-wide consumption of disk space. This leads to miscalculation in min-free-disk algo, thereby misleading DHT at some point, into thinking all sub-volumes have equal available space, in which case DHT keeps sending new file creates to subvol-0, causing it to become 100% full at some point although there ARE other subvols with ample space available. FIX: The fix is to make quota_statfs() behave as if quota xlator weren't enabled, thereby making every brick return only its local consumption and disk space availability.

* DHT: Wrong error handling in gf_defrag_migrate_dataSusant Palai2014-05-281-9/+10
| | | | | | | | | | | | | | | | | | | | | | Problem: Because of the condition (err = op_errno), err was set to zero always and ENOSPC error will be logged always. "dht_check_free_ space" was returning 1 and it was mapped to EPERM in "rebalance_task _completion". Solution: Changed the return value in dht_check_free_space to -1 as in rebalance_task_completion op_ret value -1 is mapped to ENOSPC. And fixed the wrong error condition after syncop_setxattr in gf_defrag_migrate_data.

* cluster/dht: If hashed_subvol is NULL, do not failSusant Palai2014-02-081-3/+3
| | | | | | | | | | | | | | | | | | | | | Problem: With the current implementation we are allowing unlink of a file if hashed subvol is down and cached subvol is up. For the above op to work we should have the info of hashed_subvol. But incase we do remount of the volume we will have a zeroed layout for the disconnected subvol(start=0, stop=0, err=ENOTCONN) which will result into hashed_subvol being NULL and failing unlink op. Solution: Dont fail if hashed_subvol is NULL. Check cached subvol and unlink in cached subvol. The linkto file in the hashed subvol can be remove later.

* cluster/dht: Fix layout sortingPoornima G2014-02-031-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The layout was not being sorted in the ascending order leading to the wrong detection of holes/overlaps. From looking at the previous git commits it appears that the initial version itself had the err comparison code. Deductions from the current dht_layout_sort(): 1. The zero'ed out layouts should be in the from of list, if needed 2. The layout should be sorted in the ascending order of layout error value. 3. The layout should be sorted in the ascending order of the layout 'start'. But In some cases, with the err comparison code its not sorted in the ascending order. Example: If the input is as below for dht_layout_sort(), the sorting doesn't happen in ascending order. Input: 0-1 err:0 2-3 err:0 6-7 err:0 0-0 err:20 4-5 err:0 With the current sort, Output: 4-5 err:0 0-0 err:0 0-1 err:0 2-3 err:0 6-7 err:0 Expected: 0-0 err:20 0-1 err:0 2-3 err:0 4-5 err:0 6-7 err:0 Looking at dht_layout_anomalies() it appears that, it doesn't require the layout to be sorted based on error value. The other solution was to replace line 468 with: if ((layout->list[i].err || layout->list[j].err) && (layout->list[i].start > layout->list[j].start)) Since dht_layout_anomalies() didn't expect the layout to be sorted based on the error, removed the err comparison.

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) ....

| | | | | | | | | | | | | | | | | | | | | | | | | | | stop From the history (Patch: http://review.gluster.org/4668/) When subvols-per-directory is < available subvols, then there are layouts which are not populated. This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

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.

For any request, mount 1 will return ENOTCONN, where as mount 2 will return ENOENT. This happens because for the 2nd mount, a fuse would send a lookup on '/' for any request, as it hadn't been done yet. The client xlator returns ENOTCONN, but the dht_lookup_dir_cbk changed this to ENOENT unconditionally when aggregating. So, fuse returned ENOENT, even though the errno should have been ENOTCONN.

* cli/glusterd: improve rebalance fix-layout status reportingRavishankar N2013-09-192-0/+6
| | | | | | | | | | | | | | | | | | | Problem: Currenly the CLI rebalance status command output does not indicate the 'type' of rebalance, i.e. whether a full rebalance or only a fix-layout was carried out. Fix: After the rebalance status of all peers is received by the originator glusterd, alter it to reflect the type of rebalance before passing it on to the CLI process.
