[Lustre-discuss] how do you mount mountconf (i.e. 1.6) lustre on your servers?

[Klaus Steden]

Hi Brian,

Here's a mount line from our first OSS node:

LABEL=lustre-OST0000    /mnt/lustreost0         lustre  defaults        0 0
LABEL=lustre-OST0001    /mnt/lustreost1         lustre  defaults,noauto 0 0

It has a partner, and the lines in that fstab swap the 'noauto' flag.

And from one of the client nodes:

hm0-0 at tcp0:hm0-1 at tcp0:/lustre   /mnt/lustre     lustre  defaults,_netdev 0 0

cheers,
Klaus
