Description Vijaikumar Mallikarjuna 2015-07-22 09:17:45 UTC

With the regression testcase 'tests/bugs/posix/bug-990028.t' below error are seen in the log:

[2015-07-22 09:15:06.469846] E [marker-quota.c:2527:mq_get_metadata] (--> /usr/local/lib/libglusterfs.so.0(_gf_log_callingfn+0x1b6)[0x7f0fc7015446] (--> /usr/local/lib/glusterfs/3.8dev/xlator/features/marker.so(mq_get_metadata+0x15a)[0x7f0fb717b88a] (--> /usr/local/lib/glusterfs/3.8dev/xlator/features/marker.so(mq_get_delta+0x8c)[0x7f0fb717ba3c] (--> /usr/local/lib/glusterfs/3.8dev/xlator/features/marker.so(mq_start_quota_txn_v2+0x171)[0x7f0fb717cb11] (--> /usr/local/lib/glusterfs/3.8dev/xlator/features/marker.so(mq_initiate_quota_task+0x81)[0x7f0fb717cf91] ))))) 0-patchy-marker: Failed to get metadata for /dir3



If unlink performed while the update txn is still in progress, then getxattr throws this error as the file is delete.
We need to ignore any errors from ENOENT/ESTALE

Comment 5 SATHEESARAN 2015-08-26 14:19:09 UTC

Tested with glusterfs-3.7.1-12.el7rhgs with the following steps

1. Created distribute volume and started it
2. Enabled quota on the volume
3. Set the limit on the volume
4. Fuse mount the volume
5. Continuously create and delete files from the mount point

No marker related errors are seen in brick logs, but different error messages are seen in the brick logs and I have raised a separate bug BZ 1257209 for the issue
