[SOLVED] Partition / is mounted read only

I have a problem with updating any single package and/or the entire system. The error I am getting is displayed below:

error: Partition / is mounted read only
error: not enough free disk space
error: failed to commit transaction (not enough free disk space)
Errors occurred, no packages were upgraded.

However there is plenty of disk space available:

Filesystem      Size  Used Avail Use% Mounted on
rootfs           69G   13G   54G  19% /
/dev/root        69G   13G   54G  19% /
/dev            2.0G  4.0K  2.0G   1% /dev
run             2.0G   36K  2.0G   1% /run
none            2.0G     0  2.0G   0% /dev/shm

also none of the filesystems mounted are readonly:

/dev/root on / type ext3 (rw,relatime,errors=continue,barrier=0,data=writeback,usrquota)
/dev on /dev type tmpfs (rw,relatime,mode=755)
/proc on /proc type proc (rw,relatime)
/sys on /sys type sysfs (rw,relatime)
run on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)
none on /dev/pts type devpts (rw,relatime,gid=5,mode=620)
none on /dev/shm type tmpfs (rw,relatime)

My fstab file looks as follows:

/dev/xvda1            /                       ext3     defaults        0 1
none                    /dev/pts             devpts  gid=5,mode=620  0 0
none                    /dev/shm           tmpfs   defaults        0 0
none                    /proc                 proc     defaults        0 0
none                    /sys                  sysfs    defaults        0 0
/dev/xvda2            swap                 swap    defaults        0 0

Does this look familiar to anyone? Anybody have an idea how to solve it?

Have a look at this thread. Supposedly a glibc issue by the sound of it.

Re: [SOLVED] Partition / is mounted read only

Your /etc/mtab is not a symlink to /proc/self/mounts and therefore it's quite possible that it's lying to you right now. /dev being mounted as tmpfs is another oddity...

Re: [SOLVED] Partition / is mounted read only

I got this error and solved it.I guess your vps is openvz? the latest glibc package from http://dev.archlinux.org/~ibiru/openvz/glibc-vps is 2.15-103,when I downgrade to 102,the error gone.your glibc is broken,so you should do like this.

download the 102 package and tar to root filesystem

tar -xJvf glibc-2.15-102-i686.pkg.tar.xz  -C /

Solved my problem

Me too, some kind soul should probably add this info to the wiki, or perhaps let ibiru know of the bug in 2.15-103.
