Dear all,
hei,
I am experiencing a strange problem with swap using systemd 204.
Any help in diagnosing this would be most appreciated.
I have 64 GB of physical memory,
and two 64 GB swap partitions.
Do these have the same partlabel?
I think this might couse confusion for systemd/udev
Only one of the partitions has a partlabel at all.
Output of blkid attached.
My fstab is attached.
When booting, I get a few errors related to swap; in particular:
Failed to reread /proc/swaps: File exists
In my (untested) theory this is because your swap is mounted (by the
initrd?) and while loading existing swaps from /proc/swaps systemd
tries to create /dev/disk/by-partlabel/Linux\x20swap.swap twice,
failing the second time.
My initrd does not mount swap:
http://sourceforge.net/p/kaarpux/code/ci/master/tree/master/packages/l/linux.files/init
swapon: /dev/sda3: swapon failed: Device or resource busy
probably similar to above, when sda4 comes online systemd tries to
activate all services belonging to it, blkid tells that partlabel is
"Linux swap" so systemd tries to activate
/dev/disk/by-partlabel/Linux\x20swap.swap but
/dev/disk/by-partlabel/Linux\x20swap is a symlink to /dev/sda3 which
is already activated.
[...]
even though i am not sure what is happening here, it also talks about
/dev/disk/by-partlabel/Linux\x20swap so it is probably the same issue
as above
If the above is the case and changing the partlabel of one of the swap
devices solves the problem, then this is a bug in systemd since
nothing obligates parlabel to be unique.
As per my input above, it does not seem to be a problem with identical
PARTLABELs.
However, I do think that you are on to something important here!
According to the output of systemctl --full --all --type=swap
(attached in previous mail)
it seems that systemd is trying to activate swap by every naming scheme
(id, uuid, partuuid, partlabel, /dev)
without realizing that they symlink to the the same (two) partitions.
