[lustre-discuss] Lustre clients do not mount storage automatically

[Ravi Konila]

Hi Bob

I have done that. The line in fstab is

192.168.0.50 at o2ib:/lhome    /home    lustre    defaults,_netdev    0 0

If I add mount command in rc.local twice, it works..surprise..

my rc.local has

mount –t lustre 192.168.0.50 at o2ib:/lhome    /home
mount –t lustre 192.168.0.50 at o2ib:/lhome    /home

If mounting from /etc/fstab, try adding "_netdev" as a parameter.  This forces the mount to wait until the network is ready.

  Hi
  My lustre clients does not mount lustre storage automatically on reboot.
  I tried by adding in fstab as well as in /etc/rc.local, but on reboot they don’t mount lustre file system .
  I get the following error (/var/log/messages output)

  Oct 24 15:17:40 headnode02 named[6296]: client 127.0.0.1#50559: error sending response: host unreachable

  But later on if I mount manually with the command
  mount –t lustre 192.168.0.50 at o2ib:/lhome /home, it works fine.
  My lustre version is 2.8 and RHEL 6.7

  Any suggestions?
