[lustre-discuss] new build/install no devices showing up

[Brian Andrus]

Yep. They are listed in ldev.conf:

10.1.1.1 -      mgs     zfs:lustre-mgs/mgs
10.1.1.1 -      mdt0    zfs:lustre-mdt0/mdt0
10.1.1.1 -      ost0    zfs:lustre-ost0/ost0

I haven't changed any options in /etc/sysconfig/lustre at all. Didn't 
see any that might be the source of the issue.
