[Lustre-discuss] missing ost's?

I have a small lustre test cluster with eight OST's running.  The
servers were shut off over the weekend, upon turning them back on and
trying to startup lustre I seem to have lost my OST's.

[root at node1 ~]$ lctl dl
  0 UP mgs MGS MGS 19
  1 UP mgc MGC192.168.1.254 at tcp 8acd9bf1-d1ca-8e26-1fad-bd2cf88a2957 5
  2 UP mdt MDS MDS_uuid 3
  3 UP lov lustre-mdtlov lustre-mdtlov_UUID 4
  4 UP mds lustre-MDT0000 lustre-MDT0000_UUID 3
  5 UP ost OSS OSS_uuid 3
  6 UP obdfilter lustre-OST0000 lustre-OST0000_UUID 3

Everything in the messages log appears to be fine as if it was just a
normal startup of lustre, except for the below message.  I'm not sure
what logfile the error is referring to, and the message gives little
detail on where i should start looking for an error.

Jun 16 20:13:55 node1-eth0 kernel: LustreError:
3106:0:(llog_lvfs.c:577:llog_filp_open()) logfile creation
CONFIGS/lustre-MDT0000T: -28
Jun 16 20:13:55 node1-eth0 kernel: LustreError:
3106:0:(mgc_request.c:1086:mgc_copy_llog()) Failed to copy remote log
lustre-MDT0000 (-28)

Can anyone give me an idea on what happened?

Thanks
