How is the drive management in OMV? I’m looking for something similar to UnRaid pools so i can add one drive at a time (ZFS makes you add vdevs of the same no. of drives).

I’m not too concerned with parity (ive got automated remote backups for sensitive info that I cant replace) but it would be good to know if I could swap drives out if I need to expand or replace anything too.

EDIT: with ZFS 2.3.0 supporting raid expansion, it might be worth me holding out for a year for that to become more stable, and migrate after. I only have 1 drive for now so it shouldnt be too bad if i made a new pool and moved stuff over to a 2nd drive

    What ZFS are you using?

    “As of November 2023, this feature was merged in main and is scheduled for release in OpenZFS 2.3:”

    'The OpenZFS project (ZFS on Linux, ZFS on FreeBSD) is working on a feature to allow the addition of new physical devices to existing RAID-Z vdevs. This will allow, for instance, the expansion of a 6-drive RAID-Z2 vdev into a 7-drive RAID-Z2 vdev. This will happen while the filesystem is online, and will be repeatable once the expansion is complete (e.g., 7-drive vdev → 8-drive vdev)."

      None yet. But comparisons ive seen (such as snapraid’s website) suggested it was a limitation, but they could be quite old, still.

      That’s great to know, though. So no weird plugin management just using ZFS? Or would I need MergerFS in that scenario?

      The old adage is never use v x.0 of anything, which I’d expect to go double for data integrity. Is there any particular reason ZFS gets a pass here (speaking as someone who really wants this feature). TrueNAS isn’t merging it for a couple of months yet, I believe.

        ah yeah it’s basically the first release supporting it. ah well, maybe i migrate later (i technically wont need it for a year or two with my projected data usage).

        december 2023 feels ages ago but i suppose that doesnt account for filesystems needing more rigorous testing.

    I played a bit with SnapRAID but realized there is too many ways to lose data with it; especially if you do periodic parity sync. Otherwise, it works fine.

    MergerFS works properly as far I tested it.
