[Gluster-users] Change IP address of few nodes in GFS 3.8

[Atin Mukherjee]

If the gluster nodes are peer probed through FQDNs then you’re good. If
they’re done through IPs then for every node you’d need to replace the old
IP with new IP for all the files in /var/lib/glusterd along with renaming
the filenames with have the associated old IP and restart all gluster
services. I used to have a script for this which I shared earlier in users
ML, need to dig through my mailbox and find it.
