[sheepdog-users] Suggestion on how to expand the cluster

[Valerio Pachera]

I stopped the cluster.
I added 1 disk of 2T on node "sheepdog001" and "sheepdog002".
(I don't have a third disk for the third  node right now).
Restarted the cluster on the "original" disks and checked that everything
was fine.
Then I hot added the new disks.

root at sheepdog002:~# collie node md info
Id      Size    Use     Path
root at sheepdog002:~# collie node md plug /mnt/ST2000DM001-1CH164_W1E2N5GM/
root at sheepdog002:~# collie node md info
Id      Size    Use     Path
 0      1.8 TB  40 MB   /mnt/ST2000DM001-1CH164_W1E2N5GM/



Cluster seems fine but
