Greetings!

I have 1 OST that seems like inactive device on client:
[Client] lfs df -h
UUID                     bytes      Used Available  Use% Mounted on
lustre00-MDT0000_UUID    814.8G    471.8M    767.8G    0% /mnt/lustre00[MDT:0]
lustre00-OST0000_UUID: inactive device
lustre00-OST0001_UUID      7.2T     10.4G      6.8T    0% /mnt/lustre00[OST:1]
How can I activate this device?

I have 2 OSSs theoretically configured as a failover pair using heartbeat, 1 MDS and 2 OSTs accessible from both OSS-es.
haresources:
my1.localdomain Filesystem::/dev/disk/by-id/scsi-801::/mnt/ost0::lustre
my2.localdomain Filesystem::/dev/disk/by-id/scsi-800::/mnt/mdt::lustre Filesystem::/dev/disk/by-id/scsi-802::/mnt/ost1::lustre

On both OSS-es this device seems like active:
[my2.localdomain ~]# lctl dl

  1 UP ost OSS OSS_uuid 3
  2 UP obdfilter lustre-OST0000 lustre-OST0000_UUID 3

What  am I missing?
