[Lustre-discuss] Lustre missing physical volume

Does the device show up in /dev ? 
Have you physically checked for Fibre/SAS connectivity, RAID controller errors etc? 

You may need to supply more information about your setup. It sounds more like a RAID/disk issue than a Lustre issue.

Subject: [Lustre-discuss] Lustre missing physical volume 

Just recently used heartbeat to failover resources so that I could 
power down a lustre node to add more ram and failed back to do the 
same to our second lustre node. Only then do I find that now our 
lustre install is missing a physical volume out of lvm. pvscan only 
shows three out of four partitions. 

Any hints? I've tried some recovery steps in lvm with pvcreate using 
the archived config for the missing pv but no luck, says no device 
with such uuid. I'm lost on what to do now. This is lustre 1.8.4
