I am updating our Lustre config to use Heartbeat for automated failover with Lustre 1.4.7.1 and I was checking the operations manual V36 for the exact syntax for OST failover and I am not sure if it is correct.
We wish to use active/active failover where 2 OSS see the same set of OSS and are active for half of them and passive for the other half. Up to now we have used failover in a manual way so we have config lines : --add ost --node r909n001 --ost xbb12-1a --failover --lov P-lov --dev /dev/sda --size 0 --fstype ext3 --mountfsoptions "mballoc,extents" --mkfsoptions '-N 1000000' --add ost --node r909n002 --ost xbb12-1a --failover --lov P-lov --dev /dev/sda --size 0 --fstype ext3 --mountfsoptions "mballoc,extents" --mkfsoptions '-N 1000000' For one lun, and we would failover from r909n001 to r909n002 with lconf --node r909n002 --select xbb12-1a=r909n002 /etc/lustre/lustre.xml In the manual I see a different command is used with --service and also --group is mentioned in the config file on page 61, however on page 62 --group is not mentioned so I feel something is missing. I could not find a clear answer in the KB either. I would like to use the --group option to failover all OST's with one command. Could someone clarify the syntax for OSS failover?
