| | | | | | | | | | | | | | | | | | | | | | | | | This is a backport of http://review.gluster.org/#/c/11583 During quota-update process if inode info is present in size-xattr and missing in contri-xattrs, then in function '_mq_get_metadata', we set contri-size as zero (on error -2, which means usage info present, but inode info missing). With this we are calculating wrong delta and updating the same. With this patch we are ignoring errors if inode info in xattrs are missing > Change-Id: I7940a0e299b8bb425b5b43746b1f13f775c7fb92 > BUG: 1241153 > Signed-off-by: vmallika <vmallika@redhat.com> Change-Id: Ie85fa84b5362ae179cc43402bd6a3a6d96a04b81 BUG: 1241831 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11614 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com>

* quota: support for inode quota in quota.confvmallika2015-05-071-0/+154
| | | | | | | | | | | | | | | | | | Currently when quota limit is set, corresponding gfid is set in quota.conf. This patch supports storing inode-quota limits in quota.conf and also stores additional byte for each gfid to differentiate between usage quota limit and inode quota limit.
