What puzzles me is the following output under Big Sur:
- Code: Select all
~ % sudo zpool status -v
pool: zroot
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

I don't know where this error comes from and what exactly I did to make it appear... Now I'm actually back into Catalina and started scrubbing the whole pool (unless you have a better idea of how to get rid of this error
)
Additionally what I think is a bit strange that when I was in Big Sur after a "sudo zpool export -a" followed by a "sudo zpool import -la" without unplugging the drives, "zpool status -v" showed me slightly different names:
- Code: Select all
...

PCI0@0-XHC1@14-@b:1 ONLINE 0 0 0
Back into Catalina, the output is once more a bit different:
- Code: Select all
~ % zpool status -v
pool: zroot
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

Do you have any explanation for this?
