mount includes support for systems where same partition is
shared between different devices (e.g. multipath kernel<br>
drivers). In particular case when mounting device by LABEL,
mount command reports problem with duplicate labels. You can<br>
define priority of devices in file /etc/fstab.order as simple
list of devices. The devices listed in this file have<br>
greater priority than odd devices. Devices in configuration file
have descending priority.</font><tt><br>

Subject: Re: [Ocfs2-users] OCFS2 mount problem at Linux reboot when<br>
device names are non persistent.<br>
<br>
While mount-by-uuid will work, mount-by-label should also work.<br>
The one gotcha in the latter is that it expects the device to be<br>
partitioned. As in, it will not mount-by-label if the device is /dev/sda<br>
but will if the device is /dev/sda1 or sda2, etc.<br>
