[Gluster-devel] [Gluster-users] Input/Output Error on Gluster NFS

[Peter Auyeung]

Hi Soumya

root at 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

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.

Thanks,
Soumya
