* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-26/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* quota: enhancement of build ancestryvmallika2015-03-311-90/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There can a small race window where marker accounting will be missed. Consider below example where NFS mount is used and bricks are restarted and a write operation is performed Currently: T1: lookup from protocol server, quota will initiate ancestry build T2: opendir FOP from ancestry build T3: write FOP from client T4: write_cbk T5: marker initiate accounting. There will be a problem here and txn aborts, because build_ancestry is not complete and parent not found for an inode T6: opendir_cbk T7: initiate readdirp, posix builds ancestry in readdirp With this patch, now calling readdirp on anonoymous fd during build ancestry: T1: lookup from protocol server, quota will initiate ancestry build T2: readirp FOP from ancestry build, posix builds ancestry in readdirp T3: write FOP from client T4: write_cbk T5: marker initiate accounting.

* cluster/dht: Fix min-free-disk calculations when quota-deem-statfs is onKrutika Dhananjay2014-06-021-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Problem: Assume the directory structure /quota_limit_dir/subdir and quota_limit_dir is set with some limit. When quota-deem-statfs is enabled the output of 'df /quota_limit_dir' would display quota modified values wrt to quota_limit_dir where as 'df /quota_limit_subdir/subdir' would display the quota modified values wrt volume root (/). This behaviour is not expected since, when mounted with subdirectory admin doesn't want users to know information above the subdirectory mounted. Solution: Any subdirectory within a quota_limit_dir would show the modified values as in the /quota_limit_dir. It searches for the nearest parent that has quota limit set and modifies the statvfs wrt that.

* features/quota: make writes short when the entire write cannot fit into ↵Raghavendra G2013-11-261-10/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 G2013-11-261-941/+1666
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
