Gluster users - Jan 2023 - change OS on one node

Hi to all,


I would like to replace the operating system on one gluster brick. Is it 
possible to hold the data on the brick? If yes, how can I connect the 
data partition back to the new brick.

I will remove the brick from the volume and remove the peer from the 
pool first. Then setup the new OS then I would like to configure the new 
brick and bind the exixting partion to the new brick.

Or is it better to format the brick and rereplicat the data? We only 
have 500GB of data.

I've done something similar when upgrading from EL7 to EL8.Backup
/var/lib/glusterd/ & /etc/glusterfs/ (if needed upgrade to a gluster version
that exists in both OSes) and once you install the system, install the same
gluster package version and restore the 2 dirs from backup.
Of course , a proper backup is always a good idea.
