Public bug reported:

Hi,

just installed a new HPE microserver with SSD and four harddisks with
new 21.10 server and tried to create a zpool with

zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd -O
encryption=on -O keyformat=passphrase


which reproducably crashed twice with the attached kernel message. 


The zpool then exists, but is not encrypted. 

zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd 
without the option works 

and a subsequent

zfs create pool1/sub -o encryption=on -o keyformat=passphrase

works as well. Which is, however, not a real workaround for a fully
encrypted pool (which worked under 20.04).

regards
