Re: [CentOS] Gluster - data migration.

From: Rafał Radecki radecki.rafal@gmail.com

I have two servers ("master" and "slave") with a replicated gluster volume. Recently I've had a problem with slave and gluster does not work on it now. So I would like to:

• stop and remove current volume on master (on slave it is not accessible);
• stop gluster software on master (already stopped on slave);
• remove gluster software on master and slave (previous administrator

used own built rpms, I would like to use http://download.gluster.org/pub/gluster/glusterfs/3.3/3.3.1/EPEL.repo/);

• clean old information:

setfattr -x trusted.glusterfs.volume-id /gluster setfattr -x trusted.gfid /gluster rm -rf /gluster/.glusterfs

• rsync data from master to slave;
• start gluster and create a volume with data in rsynced /gluster directory.

Are there any pitfalls I should know about?

I think you would have more answers on the glusterfs mailing list.
