-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Dear Dave, Thanks for your patience, and I'd like to ask a few more questions if I may. You mentioned that XFS is primarily for server type environment and specifically mentioned multipath access to storage devices. I had a setup in the past, blade center with a shared SCSI array where everything was duplicated. The blades had two connections one to each of a pair of switches, the switches had duplicated connections to two controllers (4 connections) and the controllers had access to the SCSI drives (a dozen). So in this scenario each blade had two SCSI drives showing for each volume on the array. So..... Does XFS bind to both devices? If so, does it start using the second if it loses access to the one it uses right now? E.g. when you do maintenance on one of the redundant switches. Also, if so, does XFS pick the device up when the device comes back (e.g. maintenance done). This assumes of course that only one of the pair is down at a time. ... Or does XFS just prevent the use of the redundant device in order to prevent problems related to writing to the same device by two FS instances?
