Podman "Invalid argument" error after node reboot #6916

Closed stephdl closed 6 months ago

stephdl commented 6 months ago

Steps to reproduce on rocky linux, not always reproducible

Expected behavior

I expect that the reboot starts all modules without issue

Actual behavior

It seems that when we start the server, before to start any user service we try to unmount a merged volume. It seems it is a random side effect, some user systemd service fails to unmount it, others succeed

I have seen this failure for openldap, sambaAD, clamav but I others experimented it for rspamd and postfix, all occurred after the reboot

we could found this for instance in my case

reboot of the server at 09:48:14 https://gist.github.com/stephdl/697992bd89198a8bf8673593e0717582

The immediate fix is to rm the merged volumes

runagent -m openldap1 rm -rf ../../.local/share/containers/storage/overlay/*/merged/

however if you try to reboot, the issue is not reproducible as is, it might occur again, or it might occur to another module

DavidePrincipi commented 6 months ago

This issue should be fixed in newer Podman releases. Just for testing, we can install the latest one on Rocky Linux 9 with

dnf -y copr enable rhcontainerbot/podman-next
dnf update

The upcoming 9.4 will ship Podman 4.9.

Concerning Debian, we have to wait Trixie (13).

As workaround we could run a script early in the boot process, to remove empty dirs that triggers the error:

( echo 'rmdir /var/lib/containers/storage/overlay/*/merged' ; getent passwd | awk -F : '$3 >= 1000 { print "rmdir " $6 "/.local/share/containers/storage/overlay/*/merged" }' ) | sh -s || :

Test case

Check the bug is not reproducible with core 2.8.0-dev.5

DavidePrincipi commented 6 months ago

Cannot reproduce the original bug, but at least the unit does not fail at boot.
