February 26, 20251 yr Hi, I have had Unraid for a long time, have a ton on my array, considering doing a ZFS pool instead. I see Truenas has a way to add new drives to expand the size of their ZFS pool. Has this been implemented in Unraid? If not, is it in the works? Have an ETA? And while I am asking questions, Is ZFS faster or slower than a normal array?
February 26, 20251 yr Solution Not yet, that is a feature of OpenZFS2.3 which is still very, very new for public use. TrueNas got it included first because they helped the OpenZFS team get it to production. ZFS expansion does still have a few caveats attached to it, it's not a magic bullet solution to ZFS's drawbacks but it does help massively. It could be in Unraid 7.1 , but no guarantees on that as a lot of testing has to be done before jumping to that version. For now, if you ahve a small ZFS pool and want to add a single disk, your best plan of attack is to dump the pool to the array or another pool, delete and rebuild the pool with the new disk, then move the data back. for small cache pools that is still pretty easy.
February 27, 20251 yr Community Expert It will be included in Unraid 7.1, which is expected to be out in March, at least a beta, but still not confirmed if there will be GUI support, or the CLI will need to be used.
