Hey folks,

quick question: I have a 3 node cluster (HC) in a production environment. I recently swapped all the storage SSDs with bigger enterprise grades SSDs. So I took a host down (migrating all VMs away, maintenance, shutdown, fix raid, gluster repair, back online).

This worked well and all three nodes are now hardware-wise replaced. The last one is still gluster-healing (roughly 20% done). The other two nodes are happily serving the vms while the third one is still in maintenance.

my question is: Can I online the maintenance node while gluster is still healing? Or will will open up a can of worms I would not like? It would be cool having all three nodes back online soon while the gluster is still repairing.

We have no urge tho. If there is a risk I would wait. If this is somewhat risk-free and do-able why not :)

with kind regards,
mit freundlichen Gruessen,
