No, drbd is not on anything: cs:StandAlone ro:Primary/Unknown
ds:Diskless/DUnknown
You have not shown the resource definition files, so we can only guess.
What has been done after / filled up? I would think at least freeing some
space and a reboot, but you don't say.

[root@wirt ~]# cat /etc/lvm/lvm.conf |grep -i filt
# A filter that tells LVM2 to only use a restricted set of devices.
# The filter consists of an array of regular expressions. These
# Don't have more than one filter line active at once: only one gets
used.
# filter = [ "r|.*|", "a|/dev/drbd[0-9]$|" ]
# filter = [ "r|/dev/cdrom|" ]
# filter = [ "a/loop/", "r/.*/" ]
# filter =[ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]
# filter = [ "a|^/dev/hda8$|", "r/.*/" ]
# Since "filter" is often overridden from command line, it is not
suitable
# for system-wide device filtering (udev rules, lvmetad). To hide
devices
# global_filter. The syntax is the same as for normal "filter"
# above. Devices that fail the global_filter are not even opened by LVM.
# global_filter = []
# The results of the filtering are cached on disk to avoid
# mlock_filter = [ "locale/locale-archive",
"gconv/gconv-modules.cache" ]
The I/O errors are expected - drbd's devices are not present or not
available. LVM may have grabbed them if your filters are not set up
correctly. Again, please provide more doc. Output from mount, your drbd
resource definition files and your LVM filters.
There was normal operation for few weeks and after out of disk space on main
partition the state of drbd changed to Diskless
The both servers was rebooted already..
Its possible to fix this in some way ?
Thanks
Piotr
