I'm trying to implement Lustre failover and I think I've gotten things working. Clients that are connected when the failover happens keep disk I/O through the failover. Now, I'm testing if a client tries to mount the FS when the MGS is in failover and I can't seem to get it to work.
Situation: Lustre 1.6.0.1 on Debian etch vanilla 2.6.20.12 kernel head2-1 is the MGS primary server (along with one MDT and 2 OSTs, one OST will be moved to another machine later) head2-2 is the fail-over for all of head2-1 services and has 1 MDT and 2 OST as its primary serives which failover to head2-1 All MDTs and OSTs have both machines listed as MGSnodes and each have their partner as failnodes. When I execute: mount -t lustre [EMAIL PROTECTED]:[EMAIL PROTECTED]:/home /home I get the following error message: mount.lustre: mount [EMAIL PROTECTED]:[EMAIL PROTECTED]:/home at /home failed: Input/output error Is the MGS running? I have the MGS on head2-1 and just swapped the order to simulate a failed condition. The Ip address is correct for our Infiniband adapters. If I swap them around it mounts just fine. What am I missing here? Also if I don't specify o2ib, it only tries to use tcp and doesn't seem to try to use o2ib on it's own.
