* features/marker: Fill loc->path before sending the control to healingVarun Shastry2014-09-222-24/+42
| | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/8296 Problem: The xattr healing part of the marker requires path to be present in the loc. Currently path is not filled while triggering from the readdirp_cbk. Solution: Current patch tries to fill the loc with path.

* features/gfid-access: Fix entry operationsPranith Kumar K2014-07-081-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/8204 Problem: When more than one aux-mounts are performing rmdir .gfid/<pargfid>/dir simultaneously, then sometimes a hang is observed. In gfid-access xlator When virtual parent/inode are replaced with real parent/inode in loc, virtual pargfid/gfid are not replaced with real pargfid/gfid respectively. Afr is using parent_loc->gfids to order the entry locks. But parent_loc->gfid contains random/virtual gfid generated by gfid-access xlator. Entrylk in client xlator is using loc->inod->gfid for sending entrylk which has 'real' gfid. Because the ordering is happening based on random gfids, One mount orders the locks as (L1, L2) where as the other orders them as (L2, L1) leading to a dead-lock thus a hang. Fix: Replace virtual pargfid/gfid with real pargfid/gfid when virtual-inodes are replaced with real-inodes in loc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/7978/ Problem: the gfid passed to ga_fill_tmp_loc() was a stack variable which the function set in the xdata dictionary. Accessing it in a later point in time gave unexpected values. This was easy to hit when AFR was involved like so: ga_mknod()--->xxx-->afr_mknod(): In afr_mknod transaction, once the stack-winds for the lock-phase are sent, the gfid in xdata becomes out of scope. When we send the actual op i.e. afr_mknod_wind(), the gfid in xdata is stale, causing posix to set junk gfids on the files. Fix: calloc the gfid and set it in the dict. Thanks to Pranith for the RCA!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quota and marker uses 'trusted.glusterfs.quota*' and 'trusted.pgfid*' xattrs to store its configurations and accounting information and also to build the parent inode chain in case of absense of path. 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> Reviewed-on: http://review.gluster.org/6838

| | | | | | | | | | | | | | | | | | | | | | | | | | available space. This patch aims to prevent creation of infinite zero byte sized files due to amount of storage available before exceeding quota limit being less than write sizes. Imagine x bytes of storage is available before we exceed quota limit and quota enforcer is receiving writes of size y and (y > x). In this scenario, if we run a shell script like: # for i in $(seq 1 10); do dd if=/dev/zero of=$i bs=y count=1; done Then, we would end up with 10 zero byte sized files, because we allow only complete writes and all writes will fail because of lack of space. However, creates succeed since a create itself will consume zero bytes. In this pattern of creates and writes, size of volume would never grow and x bytes of space will always be available and we can end up with an infinite number of zero byte sized files.

* features/quota: Improvements to quotaRaghavendra G2013-11-2610-984/+2947
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
