[Lustre-discuss] odd ost disconnects during production

[John White]

Good Morning Folks,
	We're getting some weird LustreError entries on a few OSTs in our cluster but no real disruption of service.  Any ideas what might cause such things?

n0003: LustreError: 137-5: UUID 'lrc-OST0000_UUID' is not available  for connect (no target)
n0003: LustreError: Skipped 2 previous similar messages

There are no further messages concerning this OST and the FS is still in production accessing the OST with ease.  Are these clients having a problem or OSSs?
