---------- Weitergeleitete Nachricht ---------- Subject: Re: drbd-0.7_pre4.tar.gz Date: Donnerstag, 12. Februar 2004 11:32 From: En Chiang Lee <en-chiang.lee at hp.com> To: Philipp Reisner <philipp.reisner at linbit.com>, david.zafman at hp.com Cc: bruce at kahuna.lax.cpqcorp.net, ssic-linux-users at lists.sourceforge.net Hi Philipp and David, In OpenSSI, to failover file systems from one node to another, we use the UUID to determine which device refers to the failed file system. So, we have entries as: UUID=d55a4892-d7be-455d-8509-cd24ab8b076b /home ext3 defaults,chard,node=2:1 1 2 The UUID above is the UUID of /dev/nbd/0 which is being mirrored between node2 and node1. Now, when I call "mount -a", instead of mounting /dev/nbd/0, it mounts the underlying device which is /dev/ida/c0d0p3, as reflected in the mtab /dev/2/ida/c0d0p3 on /home type ext3 (rw,chard) mount uses /proc/partitions to determine which devices to read for the particular UUID. Since the drbd devices don't have entries in /proc/partitions, only the underlying devices get checked for UUID and so get mounted. The DRBD device will never get mounted if the UUID is specified. Any suggestions as to how to get around this?
