New Synology user here.
I came from a trueNAS system that was built from a crumby computer system. The motherboard gave out, and I decided to make the switch to a more user-friendly system. I have backups of my data on two separate external USB drives, but the data is in a ZFS filesystem. Is there a way to plug directly into the DS423 and copy the files over? Thanks!
no, Synology can’t read ZFS directly.
DSM doesn’t support ZFS, so if you plug a ZFS-formatted USB drive into the DS423, it simply won’t mount or show the files. There’s no way to copy the data directly on the Synology.
What you need to do instead is use another system that can read ZFS (TrueNAS, Linux with ZFS, or a live Linux USB), mount the drive there, and then copy the files over the network to the Synology using SMB or rsync.
If you still have access to any ZFS-capable machine, that’s the easiest path.
