[SOLVED] Strange mount list

JohannesE · 2014-05-19 16:52:42

Hey,

somehow my system goes crazy and mounts many points multiple times. The output of mount is the following (shortened as it repeats the same again and again...):

rootfs on / type rootfs (rw)

In total there are 2090 lines in the output. Unfortunately, I have no idea how to debug this. Can anyone tell me where to start searching for the problem?

Cheers
Johannes

Is your /etc/mtab a symlink to /proc/self/mounts?

JohannesE · 2014-05-19 17:42:19

Thanks for the reply. No, AFAIK it's not:

habicht ~/tmp % ls -l /etc | grep mtab             
-rw-r--r--  1 root       root     92337 19. Mai 19:21 mtab

WorMzy · 2014-05-19 18:42:06

Okay, can you post the output of the following command:

pacman -Q filesystem

JohannesE · 2014-05-20 06:36:45

habicht ~ % pacman -Q filesystem
filesystem 2013.05-2

Thank you!

WorMzy · 2014-05-20 07:47:13

Hm,, weird. Can you reinstall that package, then check if your /etc/mtab is a symlink after? If not, you'll have to create it manually.

ln -sf /proc/self/mounts /etc/mtab

JohannesE · 2014-05-20 08:43:36

Reinstalling filesystem fixed it. :-)
Thanks for you support!

WorMzy · 2014-05-20 09:44:41

Glad I could help. If it happens again, check any custom cron jobs, or custom scripts you run, and make sure they're not overwriting the symlink with a regular file.
