Thank you. And yes, I agree, this needs to occur in a maintenance window and be done very carefully. :)
My only problem with this method is that I need to *replace* disks in the two servers. I don't have any empty hard drive bays, so will effectively need to put a host into maintenance mode, remove the drives, and put new drives in. I will NOT be touching the OS drives, however, as those are on their own separate RAID array. So, essentially, it will need to look something like this: - Put the cluster into global maintenance mode - Put 1 host into full maintenance mode / deactivate it - Stop gluster - Remove the storage - Add the new storage & reconfigure - Start gluster - Re-add the host to the cluster Adding the new storage & reconfiguring is the head scratcher for me, given that I don't have room for the old hard drives + new hard drives at the same time.
