You have copying a file /mnt/sharedbig/test6.jpg that has ACL
permissions. In order to use ACL, you need extended attributes support
in your underlying disk file system. GlusterFS should handle
ACL/Extended-Attributes correctly.
If you are using Ext3 as your backend disk filesystem, extended
attributes are not enabled by default. To enable extended
attributes..
Example /etc/fstab entry:
/dev/sda2 /export ext3 defaults,user_xattr 0 1
Edit your fstab like the line above and remount
# mount -o remount /export

chmod("/mnt/sharedbig/test6.jpg", 0100777) = 0
unlink("/www/thumbs/originals/0/199/199000_0.jpg") = 0
It is trying to set some ACL related xattrs and failing in the
backend. I think it is harmless. What distribution are you using?
close(1) = 0
exit_group(0)
