#11433 seems relevant. |

thanks @rincebrain . I saw it too, but i am not 100% sure whether it is the same case, thus i created new one. Here the problem comes from sending from unencrypted to encrypted parent dataset. |
|
Ah yes, encryption. For the moment, I would probably suggest just...avoiding encryption. |
|
thanks @rincebrain . I might consider LUKS + no encryption for the time being |

System information
Describe the problem you're observing
I get kernel panic on target during initial synchronization between source and ssh remote machine using syncoid. Once i get this error the only way to fix it is to reboot the target. The zfs recv process stays in "D" state on target machine.
Please suggest how i can at least kill the process.
Both machines have same version of zfs,kernel and ubuntu
I tested with any types of compression or switch it off on both sides with no luck. The only difference is that target has encrypted parent dataset and source doesn't.
Describe how to reproduce the problem
(source) sudo zfs create -o compression=lz4 ssd/private
(target) sudo zfs create -o compression=lz4 -o keyformat=passphrase -o keylocation=file:///home/xxxx/backuppass -o canmount=noauto -o encryption=on backup/encrypted
crash happens during syncoid run.
sudo syncoid --no-stream --debug --create-bookmark --no-sync-snap ssd/private root@hostname:backup/encrypted/private
Same happens with zfs-replicate which calls this command internally
zfs send -p -c -L -v -R ssd/private@snap1| ssh root@host zfs recv -F -v -s -x encryption backup/encrypted/private
The process succeeds if i send to unencrypted base dataset.
Include any warning/errors/backtraces from the system logs
