All,

 

We have a system that was grown from 3 separate lustre filesystems and I
would like to set it up so they share mgs/mdt services from a single
node (so the mount points on clients all use the same 'server'.

 

I have tried doing a writeconf and changing the mgs nid on the osts and
mdts, but when I try mounting the mdt on the new system (which already
has one mgs/mdt mounted) I get:

 

mount.lustre: mount /dev/VG_hamming/work_mdt at /mnt/lustre/work/mdt
failed: Operation already in progress

The target service is already running. (/dev/VG_hamming/work_mdt)

 

But if I immediately try again, it works.

Anyone know why this is?

 

Running lustre_1.8.5 using ext4 rpms
