LVLAaron Posted March 14 Share Posted March 14 I have a cache pool of 2x500gb drives. I want to upgrade those drives. Can I replace one at a time with a larger disk, and not need to disable/move things off my cache drive/pool? Quote Link to comment
JorgeB Posted March 14 Share Posted March 14 Assuming a redundant btrfs or zfs pool you can, one at a time: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=480419 Quote Link to comment
JonathanM Posted March 14 Share Posted March 14 Theoretically yes, but real life experience dictates that it will only go smoothly if you take the time to make a full backup beforehand. If you make a backup, you won't need it, if you don't make a backup, something will go wrong and you will lose everything. Quote Link to comment
JonathanM Posted March 14 Share Posted March 14 If you aren't sure how to check that the pool is healthy and redundant, attach your diagnostics to your next post in this thread and ask for someone to evaluate them for you. Quote Link to comment
LVLAaron Posted March 14 Author Share Posted March 14 Attached. I'm certain that it's healthy. I guess my question was... replace one, rebuild, replace the other, rebuild. Will it consume all available space? I will of course make a backup before doing anything. tower-diagnostics-20240314-1525.zip Quote Link to comment
