wickedathletes Posted July 10, 2023 Share Posted July 10, 2023 So I have a 14 disk, 2 parity array of 146TB. I have 20TB free, and most of my drives are 8 or 14tb drives. What is the most effective and efficient way to convert this array to ZFS? I believe when I switched to XFS a long time ago I manually moved files within Dolphin, formatted the drive then moved files back. That sounds like an awful process now that my array is 60+TB more. Should I use mover? Something else? Just looking for efficiency to not have this process take 2 months. Quote Link to comment
itimpi Posted July 10, 2023 Share Posted July 10, 2023 Unfortunately it is basically the same process. what are you trying to achieve by this conversion? Trying to see if you are expecting something that will not happen. Quote Link to comment
MAM59 Posted July 10, 2023 Share Posted July 10, 2023 I'm currently doing the same (but only 74Tb to shuffle 🙂 ) The only working way is to free a disk from data (move it elsewhere), reformat it to zfs and then move the next disk to the freshly formatted one. Repeat until the cows come home. Sadly I did not have had enough free space to be able to sum up 2 partitially full drives into 1 really full, so that I could format it. I had to buy a new 18Tb to start copying. But now I am already on the last disk, I guess it will be done in 2 or 3 days. But BEWARE!. I (and some others) ran into a bad 6.12 bug that slows copy speed to snail level! Read for this (with link to solution) and save yourself some weeks of waiting! Quote Link to comment

Trying to see if you are expecting something that will not happen. I really don't have a reason other than just wanting to, which sounds really dumb when said out loud. I guess I can hold off, I just know this will probably be the only time in the near future I actually have MORE space than my largest drive so the timing is now or never. It's been about 5 years since this has happened, joys of a full server. Quote Link to comment
david279 Posted July 10, 2023 Share Posted July 10, 2023 You'd do better creating a large pool with some redundancy like raidz2 and just move the data there. But converting each disk over to zfs for the hell of it is just not worth it. Quote Link to comment
