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 Thanks -Peter ________________________________________ From: Soumya Koduri [skoduri@xxxxxxxxxx] Sent: Wednesday, February 04, 2015 11:28 PM To: Peter Auyeung; gluster-users@xxxxxxxxxxx; gluster-devel@xxxxxxxxxxx Subject: Re: [Gluster-devel] Input/Output Error on Gluster NFS Hi Peter, Have you disabled Gluster-NFS ACLs . 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.
