[Gluster-users] Double counting of quota

Mon Jun 8 13:13:58 UTC 2015

OK, many thanks Rajesh.
I just wanted to add that I see a lot of warnings in the logs like the following:

[2015-06-08 13:13:10.365633] W [marker-quota.c:3162:mq_initiate_quota_task] 0-atlas-data-01-marker: inode ctx get failed, aborting quota txn

I’m not sure if this is a bug (related or not to the one you mention) or if it is normal and harmless.
Thanks,

	Alessandro

I suppose this is someway connected to the error on removexattr I’m seeing. The temporary solution I’ve found is to use rsync with the option to write the temp files to /tmp, but it would be very interesting to understand why this is happening.
