/var partition seems locked or read only
Hello.
On a distant Debian testing/unstable, it seems that the /var partition
can no longer be written: even "# touch /var/test" returns a message
saying that there is no space on the drive, which is something that "#
df -h" deny:
# df -h
Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur

/dev/sda7 447M 17K 423M 1% /tmp
/dev/sda6 14G 2,7G 8,7G 24% /var
So, I am guessing that something is locking the partition, but I have
no idea about *what* could do that. I tried disabling as many daemons
that I can, so that "# service --status-all |grep '+'" returns this:
# service --status-all |grep '+'

but it changes nothing. Any idea/supposition/whatever?
Some other informations which might help:
The problem started with a network failure, which avoided aptitude to
download, and so update, some packages, and now some packages are broken
(but dpkg was not concerned by the update). If I can still trust
/var/lib/dpkg/status, it seems that the most important breakage may come
from libasan0 (Status: install reinstreq half-configured) which is
needed by libgcc-4.8-dev, itself needed by linux-headers, so I do not
think it is the source of the problem, but... maybe?
According to /etc/mtab, the var partition is mounted as rw: "/dev/sda6
/var ext4 rw,nodev,noatime,data=ordered 0 0".
