May 26, 2020 · That way, we let ZFS familiar system administrators handling manual operations while still being compatible with ZSys. Any additional properties we need are handled via user properties on ZFS datasets directly. Basically, everything is in the ZFS pool and no additional data are needed (you can migrate your disk from one disk to another).

- Oct 06, 2007 · ZFS has significant self-healing capabilities even when used on a single disk. Specifically, the filesystem's uberblock and all metadata blocks are replicated. ZFS also allows file data to be replicated via ditto blocks. While it is possible that every copy of an block could be corrupted, this is extremely unlikely.
So I pressed import volume and extend my ZFS Pool and it added the drive as stripe. Now I do not how to remove that and put the drive back as an ata drive. If something goes wrong with a ZPOOL it is a nightmare. I Added that stupid stripe and if I reboot without the disk the whole ZFS pool dies!?!?!

To replace a device, use the “zpool replace” command followed by the pool name and the device name. If you are physically replacing a device with another device in the same location in a redundant pool, you need to identify only the replaced device. ZFS recognizes that it is a different disk in the same location.
- My ZFS pool is a set of striped mirrors that looks like this: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0. My NAS also has unoccupied drive bays so I can insert replacement drives into the system without removing a drive first.
