Lustre discuss - Apr 2009 - client mount entry for fstab with Active/Passive MGS/MDS

I have a single MDT/MGT that is hosted on a pair of MGS/MDS machines acting as a
failover pair.  Both MDS/MGS machines have visibility to the shared MDT/MGT. 
One of the two machines has the FS mounted, the other does not.

On my client side I have the following in my fstab:

10.248.58.101 at tcp0:10.248.58.100 at tcp0:/content     /content          
lustre  defaults,_netdev 0 0

I have also tried separating the machines with a "," but it
hasn''t made any run difference.  There is a difference in
/var/log/messages, but either way, it doesn''t work.

Should I be using the , or the :?  Is my syntax correct?

Thanks!

Thanks!  I think I had a parameter problem when I formatted the mgs.  I am
re-doing that now.

Andrew,
 
This is how I use it:
 
# mount -t lustre mds-0-0 at tcp0:mds-0-1 at tcp0:/npfs /mnt/npfs
 
So /etc/fstab would be something like:

mds-0-0 at tcp0:mds-0-1 at tcp0:/npfs /mnt/npfs lustre ...whatever...


Note that mds-0-0 and mds-0-1 are also MGS, despite their name.
