Gluster users - Feb 2015 - [Gluster-devel] Input/Output Error on Gluster NFS

I was trying to copy a directory of files to Gluster via NFS and getting
permission denied with Input/Output error

---> root at bizratedbstandby.bo2.shopzilla.sea (0.00)# cp -pr db /mnt/
cp: setting permissions for
`/mnt/db/full/pr_bizrate_standby_SMLS.F02-01-22-35.d': Input/output error
cp: setting permissions for
`/mnt/db/full/pr_bizrate_standby_logging.F02-02-18-10.b': Input/output error
cp: setting permissions for `/mnt/db/full/pr_bizrate_SMLS.F02-01-22-35.d':
Input/output error
cp: setting permissions for
`/mnt/db/full/pr_bizrate_standby_master.F02-02-22-00': Input/output error
cp: setting permissions for `/mnt/db/full': Input/output error
cp: setting permissions for `/mnt/db': Input/output error

Checked gluster nfs.log and etc log and bricks looks clean.
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)

Any Clue?

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
