quota/marker: dir_count accounting is not atomic
Consider below scenario: Quota enabled on pre-existing data Now quota-crawl process will start healing xattrs Now if write is performed where healing is not complete, there is a possibility that 'update txn' is started before 'create xattr txn', in this case dir count can be missed on a dir where quota size xattr is not yet created. Solution is to get size xattr and if xattr is missing, add 1 for dir_count, this requires one additional fop if done in marker during each update iteration Better solution is to us xattrop GF_XATTROP_ADD_ARRAY64_WITH_DEFAULT Change-Id: Idc8978860a3914e70c98f96effeff52e9a24e6ba BUG: 1243798 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11694 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
