Kernel Panic on zfs send | zfs receive (--raw)

Postby The Ghost of Mikey » Sat Jan 06, 2018 5:23 am

Hi,

I'm trying to zfs send | zfs receive an encrypted dataset using --raw option. Worked the last few snapshots pretty good. Now, I have a snapshot (around 5.07 GB) which (reproducible) kernel panics and the last few meters of the send|receive.

Pretty sure that’s one of the known crypto bugs. What I dont know is whether master already contains a fix or whether we are waiting for the zfs crypto guy to fix this issue upstream before merging a fix.

Cheers

would destroying the snapshot and "recreate and resend" it work?

I think it is covered by the crypto PR we are waiting for.

Also, I do like "the last few meters".

I think it is covered by the crypto PR we are waiting for.


Will u create a new release, when the PR is accepted/merged? Since this kernel panic stuff is pretty annoying and the encryption feature is way to useful to not use it anyway...

Yes there will be a release when the fix is available.

Note there is the potential for current encrypted pools to be invalid after the bug fix. Your mileage may vary!

We have put in the ticket for a new package installer, but I must admit I have not heard anything yet. I will enquire as to its status.

glad to see a new version

Note there is the potential for current encrypted pools to be invalid after the bug fix.


Can I safely upgrade with my (old) existing encrypted pool? Or is something incompatible and I need to temporary store the content of the (old) existing encrypted pool and drop/recreate that pool?

And, are the old snapshots of that (old) existing encrypted pool I 'zfs send | zfs receive'd to my Backup-Device still valid and usable (by sending new incremental snapshots). Or do I need to destroy that backup and send|receive from the beginning?

Thanks in advice!

If you have an older zfs native encrypted pool they are not compatible.

Backup, destroy and recreate is the drill I believe.
