Description Michal Svec 2012-02-11 17:25:35 UTC

After upgrade to 12.1 swap is not being activated by default after reboot,
one has to issue 'swapon -ae' by hand to make it work. The system is now
using systemd.

Comment 1 Petr Uzel 2012-02-12 13:41:45 UTC

Please post your /etc/fstab and /var/log/messages after reboot. Thx

Thanks for the logs. Could you please try with Frederic's latest systemd package:

Comment 5 Petr Uzel 2012-03-05 09:48:56 UTC

New systemd maintenance update has been released. Could you please recheck? Thanks

Comment 6 Michal Svec 2012-03-13 21:45:04 UTC

The behavior is still the same (all latest updates installed):

Comment 7 Petr Uzel 2012-03-14 10:26:06 UTC

OK, thanks for testing. I'll try to reproduce myself and see what I can do.

Comment 9 Frederic Crozat 2012-03-15 13:24:50 UTC

hmm, /var/log/messages isn't really useful. Better to reboot with "systemd.log_level=debug systemd.log_target=kmsg" and attach dmesg output.

Comment 11 Petr Uzel 2012-03-15 13:30:35 UTC

Frederic: missing dependency between swapon and MD assembly?

Comment 12 Frederic Crozat 2012-03-15 13:54:55 UTC

from the logs, swapon is started when /dev/md0 become available through udev but probably not before md.service (ie boot.md) is done..

Michal, could you attach output of "systemctl show dev-md0.swap" ?

I'm not sure if I can easily dependency on md.service on the fly (I'd prefer to avoid it if no swap is on md).

Comment 13 Michal Svec 2012-03-15 13:59:06 UTC

bash# systemctl status dev-md0.swap
dev-md0.swap - /dev/md0
  Loaded: loaded
  Active: failed since Thu, 15 Mar 2012 14:23:20 +0100; 46s ago

Comment 14 Frederic Crozat 2012-03-15 14:02:43 UTC

careful : systemctl show dev-md0.swap (not status) ;)

systemctl show dev-md0.swap

Comment 16 Michal Svec 2012-06-25 12:07:22 UTC

This seems to have been fixed meanwhile, probably with one of the
recent updates, not sure exactly when that happened.

Comment 17 Michal Svec 2012-06-25 12:07:44 UTC

Comment 18 Frederic Crozat 2012-06-25 12:18:00 UTC

just for the record, on 12.1 or on Factory ? I didn't fix anything on 12.1 regarding this (it was still on my TODO list) but on Factory, maybe needed kernel events are set now.

Comment 19 Michal Svec 2012-06-26 07:15:12 UTC

12.1. There have been like two (or more) systemd package updates lately
and I assume one of them fixed that.

Comment 20 Frederic Crozat 2012-06-26 07:25:55 UTC

ok, thanks :)
