Trouble with mounted partitions (root twice)

ethail · 2011-05-10 16:32:02

Since a few days ago, I'm experiencing troubles with my partitions, like / being mounted twice. I'm using systemd instead of Init, mtab is symlinked to /proc/self/mounts

df output:

rootfs 103212320 13629136 84340304 14% /
udev 10240 0 10240 0% /dev

/dev/disk/by-uuid/11331a92-bb2a-4aa2-a376-de9c2d12d6a3 103212320 13629136 84340304 14% /
tmpfs 2011176 0 2011176 0% /dev/shm
tmpfs 2011176 176 2011000 1% /sys/fs/cgroup
tmpfs 2011176 0 2011176 0% /media
run 10240 344 9896 4% /var/lock
run 10240 344 9896 4% /var/run
/dev/sda1 369251368 61124056 289370348 18% /media/Akai-Data

As you can see, / is mounted twice.

my /proc/self/mounts looks like this (in fact, is):

http://pastebin.com/bLi22Cps

my partition layout inherit from the time where I had both Windows and Arch Linux installed (so I was low on free primary partitions) is: sda1 350 GB ext4, sda3 8 GB swap, sda4 98 GB ext4. So I have no /home and / in different partitions as sda1 is where I have all my data.

my /etc/fstab:

devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
/dev/sda1 /media/Akai-Data ext4 defaults,realtime,data=writeback 0 2
/dev/sda3 swap swap defaults 0 0
/dev/sda4 / ext4 defaults,user_xattr,realtime,data=writeback 0 1

Also, my /tmp folder has not being cleaned in 5 days. ¿Does it not supposed to be cleaned at every boot/shutdown (I have booted few times in five days)?

So, my troubles here are:

/ is mounted twice, and /tmp is not being cleaned. Any clue on this?

Also, to me, my/proc/self/mounts seems weird, aside from the fact that I think there is why / is mounted twice. Could someone check that?

Thank you in advance.

I am really puzzled by this :
/dev/disk/by-uuid/11331a92-bb2a-4aa2-a376-de9c2d12d6a3

Nowhere, that I can see, have you specified anything by UUID

Is there a chance that some other script ( /etc/rc.local maybe) is reaching out with an invisible hand is mounting something ?

The only place I have found that is on my /boot/burg/burg.cfg file:

linux /boot/vmlinuz26-pf root=/dev/disk/by-uuid/11331a92-bb2a-4aa2-a376-de9c2d12d6a3 ro fastboot quiet logo.nologo resume=/dev/sda3 init=/sbi/e4rat-preload

But as far as I can remember, that has been always there since I started using burg instead of grub (half of a mont ago, maybe more). And never got troubles with that.

Also, rc.local has everything comented out

EDIT: have I to assume that the burg entry is leading to troubles?

Ok, so I have changed my burg.cfg entries to root=/dev/sda4.
df still shows / as mounted twice but seems to be "normal" acording to this thread:
https://bbs.archlinux.org/viewtopic.php?id=99417

What still has me worried is the fact that my /tmp folder has not be cleaned since 6 days ago.
