cli/glusterd: Changes to quota command Quota feature
re-work. Following are the cli commands that are new/re-worked: ====================================================== volume quota <VOLNAME> {enable|disable|list [<path> ...]|remove <path>| default-soft-limit <percent>} | volume quota <VOLNAME> {limit-usage <path> <size> [<percent>]} | volume quota <VOLNAME> {alert-time|soft-timeout|hard-timeout} {<time>} volume status [all | <VOLNAME> [nfs|shd|<BRICK>|quotad]] [detail|clients|mem|inode|fd|callpool] volume statedump <VOLNAME> [nfs|quotad] [all|mem|iobuf|callpool|priv|fd|inode|history] glusterd changes: ================= * Quota limits are now set as extended attributes by glusterd from the aux mount created by the cli. * The gfids of the directories on which quota limits are set for a given volume are stored in /var/lib/glusterd/vols/<volname>/quota.conf file in binary format, and whose cksum and version is stored in /var/lib/glusterd/vols/<volname>/quota.cksum.
