Hi,

I'm puzzled by the following behavior.
An active-passive failover pair of metadata servers have separated MGS and
MDT disks and two networks (o2ib and tcp0(eth0)):

mds1: [EMAIL PROTECTED]  [EMAIL PROTECTED]
mds2: [EMAIL PROTECTED]  [EMAIL PROTECTED]

MGS and MDT are formatted with the options:
[EMAIL PROTECTED],[EMAIL PROTECTED]
[EMAIL PROTECTED],[EMAIL PROTECTED],[EMAIL PROTECTED],[EMAIL PROTECTED]

The _first_ mount of an OST fails if mds1 is the active metadata server.
It succeeds when mds2 is active.

With client mounts I have seen something similar. I could mount clients
with
   mount -t lustre [EMAIL PROTECTED]:[EMAIL PROTECTED]:/lustre /mnt/lustre
but not with
   mount -t lustre [EMAIL PROTECTED]:[EMAIL PROTECTED]:/lustre /mnt/lustre
when mds1 was the active MDS. This suggests that the active MDS has to be
the last one on the list.

Strange enough, in my current lab setup I cannot reproduce the client
mount behavior any more.

Did anybody else see this kind of behavior? Are there any reasons for this?

Thanks & best regards,
Erich
