Bug#760501: coreutils: df does not show LVM root partiton

[Gonzalo Marcote Peña <gonzalomarcote@gmail.com>]

I went ahead and created one symlink from /etc/mtab to /proc/mounts and now I show the info without issues:

# ls -l /etc/mtab; df -hT; mount

lrwxrwxrwx 1 root root 12 sep  5 10:30 /etc/mtab -> /proc/mounts

If you need more info from my side for why this happened on the installation I will be glad to provide it.

Hi Mike,

Here is the output:

# ls -l /etc/mtab

-rw-r--r-- 1 root root 387 sep  5 10:02 /etc/mtab

# cat /etc/mtab

tmpfs /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0

tmpfs /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0

/dev/sda1 /boot ext2 rw 0 0

/dev/mapper/pulsar-home /home ext4 rw 0 0

rpc_pipefs /run/rpc_pipefs rpc_pipefs rw 0 0

binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0

gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=gonzalo 0 0

However in another jessie installations I see that /etc/mtab is a symlink that points to /proc/mounts

In my case I did one jessie install over one previous partitioned LVM structure (from another previous distro).

And I did another installation in nother PC with the same weekly jessie iso and this didn't happen.

So how seems that mtab is not complete. So should I create one symlink from /etc/mtab to /proc/mounts?

Regards

This is the /proc/mounts output:

After a new clean jessie installation df command or mount command does not show / root parition:

Sounds like a problem with /etc/mtab configuration. It doesn't sound like a coreutils problem if it's also affecting mount. What is the output of

ls -l /etc/mtab
cat /etc/mtab
