Hello,
We're running/building Lustre on ZFS and I noticed that when using
mkfs.lustre on a zpool, when creating the MDT, with two --mgsnid
parameters, one for the MGS and one for the MGS fail over, causes a
problem resulting in not being able to mount the MDT. (I think it tries
to connect to
I just ran into this same issue last week. There is a JIRA ticket on it at
Intel but in a nutshell mkfs.lustre on zfs will only record the last mgsnode
you specify in your command. To add an additional fail node you can use the zfs
command to update the configuration:
zfs set
Oh - BTW. You will need to do the same thing with your OSTs for setting both
the mgsnodes.
Also, you can use zfs show zpool name/zpool volume to get the same info as
you would with tunefs.lustre
