zfs setup package - missing dependencies leads to failed setup

Hello!
I just - for testing - setup ZFS in a kvm guest.
If fails miserably, because the package has left off dependencies.
I am listing the problem messages here (and a bad solution further down).

Re: zfs setup package - missing dependencies leads to failed setup

I don't know if this related, but I ran into a problem installing zfs (on daedalus on PC).
The building of the module hangs and and I had to stop it.
Now I can also not remove it because it says:
dpkg was interrupted, you must manually run 'dpkg --reconfigure -a'
to correct the problem.

But when I do that it hangs again.
Can someone please tell me what can be done about this?

Edit:
OK, I ran it again after a reboot and after a very long time, it finished with unconfigured packages.
I then ran remove and autoremove
and it looks ok now.

So, how can I install zfs, please?

Re: zfs setup package - missing dependencies leads to failed setup

OK, I got it to work!
So, maybe that someone else has some use of what I did:

nano /etc/apt/sources.list

deb http://deb.devuan.org/merged daedalus main non-free-firmware non-free contrib
deb http://deb.devuan.org/merged daedalus-updates main non-free-firmware non-free contrib
deb http://deb.devuan.org/merged daedalus-security main non-free-firmware non-free contrib
deb http://deb.devuan.org/merged daedalus-backports main non-free-firmware non-free contrib

apt update

apt install linux-headers-$(uname -r) linux-image-amd64  kmod zfsutils-linux
apt install zfsutils-linux zfs-dkms zfs-zed
zpool import stor -f
zpool list

zfs list
NAME   USED  AVAIL     REFER  MOUNTPOINT
stor  1.31M  3.51T      128K  /zfs

Success!

I hope I did not miss anything, since this was done after a previous failure.

Re: zfs setup package - missing dependencies leads to failed setup

Hi!
Exactly, what I did (just not listed lile "headers-$(uname -r), but my real kernel version).
Additionally, I required the version form backports (because I need the block-copy feature).
From my first failed setup, I have to add: Use grub-pc from backports too, it may otherwise
fail after pool snapshots!
But it remains problematic and I am unsure, to continue:
- In my real hardware setup, I am getting an error message at each shutdown (postet this here).
- In another kvm/qemu setup, where NO pools are in use, but just ZFS setup, it crashes at each shutdown.
May be, there is an undiscovered problem with non-systemd systems - worked perfectly for me on debian.

Manfred

Re: zfs setup package - missing dependencies leads to failed setup

Hi!
On my VM, I removed backports and ZFS and started from scratch
(was a bit tricky to remove 'grub-pc' from backports).
Installation of ZFS 2.1.11 went smootly, no errors.
But, with the "cannot unmount /var/log" from my hardware in mind,
I looked at shutdown and the I see this:

Stopping ZFS Event Daemon
Unloading modules rmmod: ERROR: Module zcommon is in use by icp
rmmod ERROR: Module znvpais is in use by: zcommon
rmmod: ERROR: Module spl is in use by: icp zstd znvpair zcommon
FAILED!

There are NO pools, but an extra disk, which contains a pool (which has not und should not be importet)

With this VM, using zfs 2.4, I created two clones (on ZFS volumes for VMs) and they have the same error
like the hardware installation:

Unsharing ZFS filesystems.
Stopping ZFS Event Daemon.
Unmounting ZFS filesystems cannot unmount '/var/pool': pool or dataset is busy

Lost my hope!

Re: zfs setup package - missing dependencies leads to failed setup

I have not seen these kinds of problems.
If I have time, I will make a Virtualbox VM and install Daeldalus and zfs and see how it goes.

Re: zfs setup package - missing dependencies leads to failed setup

Hi!
Thanks!

This is nearly, what I usually do (have only SSHD and some networking tools - I usually keep this as
a bootable installation on first partition as "repair-inst", with the same version of ZFS which I'll use
to setup zfs on root (onto anohter disk). Using ether netinstall, or, naturallay, for zfs on root the
debootstrap tool, how it is described. One different thing is, that I first install DKMS separately and
the wanted kernel with headers.

And you describe exactly ("image1"), what I am experiencing. What you see

"I didn't look further what error it was (sorry)."

is a dependency problem, which left a part uninitialized, which becomes "repaired" if you repeat the
step - independently, that you' made it a little differently (which is not neccessary, because all this
is in dependencies).

I have the (already) described problem with shutdown. If I add pools, they dont have a problem
and working properly like your's.

But I am not keeping installations, which have improperly behavior on stutdown (or startup).
For my ZFS-VMs (which are KVM/QEMU), I initiate a shutdown from inside and keep the
mouse-pointer (on the host) on the pause button, which I press at the moment, the red errorline appears.
On a new hardware, this is the same - but I cannot stop the display .... and they dont appear in logs,
and for my other cases, it is theit is the root-filesystem on unmount!

My older (and running) installations dont have errors or this behavior.
On my day-work machine (which ist Debian Bullseye, ZFS on root), no errors appear, wether
at startup or shutdown (and even my fileserver, staying on Debian Buster, ZFS on root, is error-free).

The 2.4 version (in backports), which I need due to the block-copy feature, is even crashing
hard at shutdown.

Usually, zfs-setup is easy (except for on root) and causes no errors - I am using it since
2012 (not on root at that time).

Regards,
Manfred
