Anyone got this working on emc powerpath? I remeber seeing somewhere some special configuration to get mounting by label working with multipath devices, but could not find it again. Regards, Luis

While mount-by-uuid will work, mount-by-label should also work. The one gotcha in the latter is that it expects the device to be partitioned. As in, it will not mount-by-label if the device is /dev/sda but will if the device is /dev/sda1 or sda2, etc. Randy Ramsdell wrote: > Ricardo Fernandez wrote: > >> Hi, >> >> I have the following problem when the servers accessing OCFS2 reboot: >> as the Linux device names are non persistent, at reboot they usually >> change, and then OCFS2 can't mount the device because it is expecting >> a different device name as stated in the fstab file.
