I'm not sure where to start with this problem which is the reason for this
post! I have a small test cluster setup and not a lot of experience yet..

After rebooting the servers (via reboot cmd) I am no longer able to mount
the FS from any of the servers where I previously could.
When I try to mount the FS I receive the following error.

'mount -t lustre 1.1.1.1 at tcp0:/lustre /mnt/lustre'

mount.lustre: mount 1.1.1.1 at tcp0:/lustre at /mnt/lustre failed: No such
device
Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
Note 'alias lustre llite' should be removed from modprobe.conf

lctl list_nids (results in)
1.1.1.1 at tcp

lctl dl (results in)
  0 UP mgs MGS MGS 7
  1 UP mgc MGC1.1.1.1 at tcp 29f04cc2-d96e-0ef1-5680-6113df98ea84 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 4
  5 UP osc lustre-OST0000-osc lustre-mdtlov_UUID 5
  6 UP osc lustre-OST0001-osc lustre-mdtlov_UUID 5
  7 UP ost OSS OSS_uuid 3
  8 UP obdfilter lustre-OST0000 lustre-OST0000_UUID 5


HOWEVER, my client machines are able to mount the FS without any problem.

'mount -t lustre 1.1.1.1 at tcp0:/lustre /mnt/lustre'

lfs df -h
