* libxlator: Make sure marker_xattr is validPranith Kumar K2015-03-091-13/+17
| | | | | | | | | | | | | | | | | | | Problem: marker_xattr is allocated only when the op_ret is 0. If the final response is a failure, then the marker time is dict_set with key as NULL. this will be changed to ref:<address-of-value> by dict_set, so the value won't appear on the marker-key when the getxattr_cbk is in dht. So dht unwinds with failure EINVAL. Fix: Always populate marker_xattr. Fixed dict mem-leak as well.

* features/quota: Improvements to quotaRaghavendra G2013-11-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* cluster/*: get logic to calculate min() of the 'stime' xattrAvra Sengupta2013-07-142-2/+57
| | | | | | | | | | | | | | | | | | | | | | * in both distribute and replicate (ignoring stripe for now), add logic to calculate the min() of stime values. * What is a 'stime' ? Why is this required: - stime means 'slave xtime', mainly used to keep track of slave node's sync status when distributed geo-replication is used. Logic of calculating 'min()' for this stime is very important as in case of crashes/reboots/shutdown, we will have to 'restart' with crawling from stime time value from the mount point, which gives the 'min()' of all the bricks, which means, we don't miss syncing any files in the above cases.
