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

[Soumya Koduri]

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
