Re: change OS on one node

[Strahil Nikolov <hunter86_bg@xxxxxxxxx>]

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.

Best Regards,

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.
