Hi Strahil,
interesting, would you happen to know how you could let oVirt mount it with this flag?
Thanks Olaf

Also it has a typo.Obviously I needed more coffee or a bigger break.It should be treated as 'relatime/noatime reduce the ammount of I/O requests to your brick physical device , which increases performance by reducing unnecessary IOPS'Same is valid for SELINUX's mount option:context="system_u:object_r:glusterd_brick_t:s0" . It instructs the kernel to 'getfattr' each file in the brick as it has a specific selinux context (this case Gluster brick files), thus reducing unnecessary IOPS.Best Regards,Strahil Nikolov

It could be read like "noatime slows down your brick" while, IIUC, it
really means it *improves* the brick's performance by reducing the
number of "housekeeping" IOs.
