     Probably could resync faster if I set some kernel parameters, but it doesn't really matter.

     @splitshockvirus@mstdn.starnix.network sync times are another reason to use btrfs for RAID which does all the sync/parity calculations on each write. Saves so much time :)

     Doing this 6 times, so 3 hours resyncing disks.
