Hi Soumya root@glusterprod001:~# gluster volume info | grep nfs.acl 02/05/15 10:00:05 [ /root ] Seems like we do not have ACL enabled. nfs client is a RHEL4 standard NFS client
Oh by default ACLs are enabled. It seem to be shown in 'gluster volume info' only if we explicitly modify its value to ON/OFF.
Can you please verify if the filesystem where your Gluster bricks have been created has been mounted with ACLs enabled.
Thanks, Soumya

Please check the option value - #gluster v info | grep nfs.acl nfs.acl: ON Also please provide the details of the nfs-client you are using. Typically, nfs-clients seem to issue getxattr before doing setxattr/removexattr operations and return 'ENOTSUPP' incase of ACLs disabled. But from the strace, looks like the client has issued 'removexattr' of 'system.posix_acl_default' which returned EIO. Anyways, 'removexattr' should also have returned EOPNOTSUPP instead of EIO.

The files ends up able to copy over with right permission. Stack trace the copy and seems like it failed on removexattr removexattr("/mnt/db", "system.posix_acl_default"...) = -1 EIO (Input/output error) http://pastie.org/9884810 Any Clue?
