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

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
