If the data in question hasn’t been accessed recently (the 15m of tx you reversed), then there shouldn’t be any issue.
3x 4T would give you either: 1 RAIDZ, 1 mirror + spare. RAIDZ has been recommended against for a good decade now. I’d suggest RAIDZ2. It has a minimum of 4 requirement. Since you’ve been using the zpool command already, run ‘zpool status <pool name>’. You should see a line ‘config:’ and below that, your disk layout. Creating a pool of mismatched drive sizes will technically work, but isn’t optimal or recommended. Given that you have 3x4T, I’d suggest getting a 4th one and build your RAIDZ2 that way. > On Oct 1, 2019, at 12:30 PM, mich...@robinson-west.com wrote: > > I learned to use the zpool command from a command line and did a 15 minute > reversal of the transactions. > > How much damage if any has been done though to my data?
