I have a fair-sized pool I would like to redo.
Current is an 11 wide raidz1 pool.
I want to change this to 2ea 5-wide raidz1 vdevs with the remaining disk as a hot spare.
I have a free 12tb disk I can do a replication to in order to migrate the data.
Question is: Do I do a migration at the root level of this pool, or do each data-set individually?
I do have smb shares, I assume I screenshot the permissions and such to document those.
Thoughts, suggestions, gotcha’s are welcome.
thanks!
I always prefer to do replication on a per dataset but you can do it at the root of the pool as well, just make sure you choose the recursive potion. Also, make sure you have a backup since moving everything to a single drive is risky if that drive were to fail.
hey thanks Tom for the input! Any gotcha’s with this having the application data set?
Also, with shares, do I need to remove them before i delete the pool and move them to the temp drive?
I never move the apps, I just rebuild them when I setup a new pool, but they do have a new app moving feature in 2025.10 that makes that easier. The shares will get auto destroyed when you remove the old pool and will have to be manually recreated in the new pool.
