[Lustre-discuss] Lustre on mpath devices

[Klaus Steden]

What about the FS label, i.e. LUSTRE-OST0001 (which is what's actually in my
/etc/fstab, even though Lustre mounts a specific device)?

Does a multipathed setup automatically address failover, or is STONITH
configuration still required to automatically remap devices normally served
by downed servers?

thanks,
Klaus
