Error after updates a zfs kernal

Today, I tried to update a zfs kernal (something, just one package). And errors appeared.

First, the zfs plugin could not detect pools.

Second, when I log out the Web GUI, I could not open the website anymore.

Third, I try to reboot. After reboot, I found lots of services failed to start, including `rrdcached`, `openmediavault iptables firewall`, `chrony` and `chronyd`.

Error message is like:

1. rrdcached

4:12 PM rrdcached.service: Failed with result 'exit-code'.
4:12 PM rrdcached.service: Control process exited, code=exited, status=2/INVALIDARGUMENT

2. openmediavault iptables firewall

4:12 PM Failed to start openmediavault iptables firewall service.

4:10 PM Stopping openmediavault iptables firewall service...

3. chrony & chronyd‘s error could be solved with methods in here: Chronyd and Chrony services failed to start

(1) Edit /etc/default/chrony and change DAEMON_OPTS="-F -1" to DAEMON_OPTS=""

(2) Start chronyd systemctl start chronyd check status systemclt status chronyd

But I'm not sure whether the error of chrony & chronyd would appear again in the next reboot.

Any helps? Thanks a lot!

By the way, when trying to update a package in OMV (in the update management section), it's a matter of life and death. Are there any safer way to do this?

Also, I found the omv-salt had been lost in OMV. I think there must be more potential problems after trying to update the zfs-kernal package. The zfs-kernal package was not update normally with lots of errors.

Oh, rrdcached error had been soloved just via:

sudo apt-get install -y rrdcached 

The openmediavault iptables firewall error could also been solved:

1. Download the helper function from: https://github.com/openmediava…re/openmediavault/scripts

2. Go to /usr/share/openmediavault/. Greate /share/. Put the helper-functions into the dir.

3. Restart the openmediavault iptables firewall.

Done.

However, the web GUI of OMV could not been open, which means the existence of other problems.

I notices that the omv-envr, omv-salt had been loss. I check packages related to omv:

$ dpkg -l|grep -E "omv|openmediavault"

rc  openmediavault                       5.6.8-1                             all          openmediavault - The open network attached storage solution
ii  openmediavault-keyring               1.0                                 all          GnuPG archive keys of the OpenMediaVault archive
rc  openmediavault-lvm2                  5.0.2-1                             all          openmediavault Logical Volume Manager (LVM2) plugin
rc  openmediavault-omvextrasorg          5.6                                 all          OMV-Extras.org Package Repositories for OpenMediaVault
rc  openmediavault-zfs                   5.0.6                               amd64        OpenMediaVault plugin for ZFS

I think reinstall these packages might help.

Any suggestions?

Here I display the loss of omv-salt :

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/sbin

$ which omv-salt
<return nothing>

Hope it can help for somebody. Thanks!

Surprisingly, I finally deal with the problems by myself. And...

My OMV upgrade from 5.x to 6.x...

Here are the processes:

1. sudo apt-get update

2. sudo apt-get -y upgrade

3. if needed, load sudo apt-get -y upgrade --fix-missing # debian

4. sudo apt-get dist-upgrade # omv

5. According to (Error salt), wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash

6. sudo reboot

Sometimes, there were some errors happening. Just repeated them and reboot.

One of annoying error is proftpd dependency. According to https://bugs.launchpad.net/ubu…proftpd-dfsg/+bug/1933318, you can try

(1) sudo apt-get remove proftpd*

(2) sudo apt-get purge proftpd*

(3) sudo apt-get install proftpd*

(4) sudo service proftpd start

Anyway, finally, You can check:

$ dpkg -l | grep openmediavault

ii  openmediavault                       6.0.7-1                         all          openmediavault - The open network attached storage solution
ii  openmediavault-keyring               1.0                             all          GnuPG archive keys of the OpenMediaVault archive

rc  openmediavault-omvextrasorg          5.6                             all          OMV-Extras.org Package Repositories for OpenMediaVault
rc  openmediavault-zfs                   5.0.6                           amd64        OpenMediaVault plugin for ZFS

If you meet GUI login problem: 500-Internal Server Error Failed to connect to socket: No such file or directory. According to OMV GUI Login Error: Failed to connect to socket: No such file or directory, just try

systemctl status openmediavault-engined 
systemctl unmask openmediavault-engined # if the statu is masked, just unmask it
systemctl start openmediavault-engined

Succed.

Very hard.

Also, here is a tip: upgrade pakage by using sudo apt-get dist-upgrade instead of doing it in the GUI.

Thanks for reminding. Soma  macom

The original reason for me to upgrade packages is to fix problems of login instead of upgrading to OMV 6.x. But now the login is normal, so I think it doesn't matter whether the 5.x or 6.x was installed.

Now I had enter the new GUI, whose appearance is very different from OMV 5.x. After reboot, the OMV had nothing change, which showed that the version in my NAS is stable. However, check the version of OMV:

$ cat /etc/issue

openmediavault 6.0.7-1 (Shaitan) \n \l

$ uname -a

emm...Very interesting.

Does it matter?

Soma

Thanks for reminding.

OMV-extras and plugins had been upgraded. Now everything seems OK.
