Hi Jagga, You can simply mount your MDT and OST with options "errors=panic". In case of fibre disconnection, Lustre OSS/MDS will get IO errors and panic the node so that other node can take over.
With this option, your /etc/ha.d/haresources file would look like: mds1 LVM::homevg Filesystem::/dev/homevg/home::/mnt/home::lustre::errors=panic Cheers, _Atul Jagga Soorma wrote: > Hi Guys, > > My MDT is setup with LVM and I was able to test failover based on the > Volume Group failing on my MDS (by unplugging both fibre cables). > However, for my OST's, I have created filesystems directly on the SAN > luns and when I unplug the fibre cables on my OSS, heartbeat does not > detect failure for the filesystem since it shows as mounted.
