systemd 213.9 related issues (presumably)

Hello

I had the same issue that many of us experienced: the system would not reboot after the recent systemd upgrade. I followed the method described elsewhere (cf. viewtopic.php?f=47&t=7330&p=40153&hilit=systemd#p40153 i.e. reverting back to systemd 212-3) to get my system working again, and soon after that upgraded to systemd 213-9.1.

$this->bbcode_second_pass_code('', ' [root@archy2 ~]# pacman -Q | grep systemd
libsystemd 213-9.1
systemd 213-9.1
systemd-sysvcompat 213-9.1
')

This system was before the upgrade a freshly installed system (utilite hardware), with dovecot and nfsd working. But both with the downgrade to 212-3 and after the re-upgrade to 213-9.1 I have the following services failing:

$this->bbcode_second_pass_code('', ' dovecot.service loaded failed failed Dovecot IMAP/POP3 email ser
nfsd.service loaded failed failed NFS Server Daemon
systemd-modules-load.service loaded failed failed Load Kernel Modules')

with details:

Also (trying the suggestion in the log above)

$this->bbcode_second_pass_code('', ' [root@archy2 ~]# mount -t nfsd nfsd /proc/fs/nfsd
mount: unknown filesystem type 'nfsd'
[root@archy2 ~]# ')

I guess these are all somehow related to the systemd upgrade. Any suggestions about how to proceed?

Thank you for your attention

Systemd 213-9.1 has cgroups xattr disabled, so this in particular is not the case. Have a look at /etc/passwd.pacnew

viewtopic.php?f=58&t=7396&p=40536#p40536

Thank you for the suggestion.

I checked /etc/passwd and /etc/group and found only some minor differences such as /bin/false instead of /usr/bin/nologin, which I fixed; but no missing entries.

So, the problem persists.

I have been digging a little deeper, starting with the first failing service (systemd-modules-load.service). The only module needed is

$this->bbcode_second_pass_code('', '[root@archy2 systemd]# cat /usr/lib/modules-load.d/nfs-utils.conf
nfs
[root@archy2 systemd]# lsmod
Module Size Used by
[root@archy2 systemd]# modprobe nfs
[root@archy2 systemd]# lsmod
Module Size Used by
[root@archy2 systemd]# ')

Now I get suspicious: no modules loaded at all? Is this supported in the utilite provided kernel? How can I check?

I also didn't find any nfs module, only nfsd

$this->bbcode_second_pass_code('', '[root@archy2 modules]# find /usr/lib/modules -type f -name \*nfs\* -print
/usr/lib/modules/3.0.35-16-ARCH/kernel/fs/nfsd/nfsd.ko.gz
[root@archy2 modules]# modprobe nfsd
[root@archy2 modules]# lsmod
Module Size Used by
[root@archy2 modules]# ')

Yet I had nfs working before the systemd upgrade...

Use uname -r to check which kernel is currently running, I guess it's not 3.0.35-16-ARCH.

[sleepymonad]

That was spot on!

While trying to troubleshoot the issue, I had replaced the kernel with the one from the install media : 3.0.35-15-ARCH. And then, I kind of forgot.. .the joys of multitasking.

Thank you very much
