Hello,
My main storage is running Truenas Scale Dragonfish-24.04.2 with zfs-2.2.4-1.
My backup server is running Ubuntu server 24.04.1 with zfs-2.2.2.
I have been backing up my ZFS pool using syncoid (with --preserve-properties), though it has started failing at backing up Zvols. This seems to be caused by some new Zvol properties that were added to truenas/zfs nut not yet released in openzfs/zfs.
The properties I see missing are: “prefetch”, “volthreading”, “org.truenas:managedby” and “org.freenas:description”.
“volthreading” for example was meged back to openzfz/zfz, but never made it to any release.
Is there any way to port these new features in truenas/zfs to a machine runing Ubuntu?
Thanks!
I’m not familiar with syncoid, but not being able to handle ZFS user properties like org.truenas:managedby is a pretty significant bug.
The other properties are available and documented in openzfs, but not in the version you’re using.

Syncoid seems to be passing the Zvol properties with zfs send ... | zfs receive -o zvol.prop1 -o zvol.prop2...
I don’t think it is having issues with org.truenas:managedby, it seems to only complain about volthreading with this error: cannot receive: invalid property 'volthreading'
I don’t think this is a bug, just incompatible versions of zfs between the two systems. I was just wondering if it is possible to somehow run Truenas version of ZFS on Debian/Ubuntu.
