features/quota: Metadata cleanup
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
