EDIT:
I was able to identify the issue. There's no kernel panics when calling zfs commands with sudo.
So, this one works for me:
- Code: Select all
zfs send Tank/Databases/foo@2020-12-16-dump | ssh host sudo /usr/local/zfs/bin/zfs receive Tank/Databases/foo
Same goes for other commands like
- Code: Select all
$ zfs create Tank/foobar
- Code: Select all
$ sudo zfs create Tank/foobar
To reproduce it you need to allow user certain permissions:
- Code: Select all
$ sudo zfs allow -u <username> compression,mountpoint,create,mount,receive Tank
- Code: Select all
$ zfs allow Tank
---- Permissions on Tank ---------------------------------------------
Local+Descendent permissions:
user <username> compression,create,mount,mountpoint,receive
