-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 We are using a home-grown set of init scripts. There is an "lnet" init script to bring up the lnet networking, and a "lustre" init script to start lustre services.
We tend to be paranoid about the possibility of double mounting a multi-homed LUNs, so failover for us requires a sysadmin to manually issue the command to move a LUN to the failover node. We have a custom udev script to detect any available LUNs on a node, identify them as normal or backup lustre devices, and name them accordingly under /dev/lustre. The lustre init script runs an optional journal-replay-only fsck on each device before issuing a mount command to start the lustre service. Chris Brian J.
