[Gluster-users] Importing bricks/datastore into new gluster
Contemplating upgrading my proxmox clusterby a major revision, which unfortunately basically involves destroying and recreating each node. A major PITA. The gluster bricks are all sitting on top of ZFS, so its easy enough to preserve their data across the reinstall, but I will have to reinstall gluster and recreate the setup (peers, datastore etc). Can I safely recreate the bricks on top of the existing datastructure and avoid restoring/resyncing all the data (2.5TB). I'm worried about inadvertently creating a splitbrain problem. If its risky I can just create a empty gluster datastore, then move the data onto one node and allow it to sync to the others over the weekend, only 1GB Ethernet unfortunately :( -- Lindsay -------------- next part -------------- An HTML attachment was scrubbed...
