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 _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
