thanks for your reply, but they are already:
/dev/mapper/eltarun-root on / type ext4 (rw,noatime,errors=remount-ro)
/dev/mapper/eltarun-debian32 on /mnt/debian32 type ext4 (rw,noatime)
/dev/mapper/eltarun-recordings on /mnt/recordings type ext4 (rw,noatime)
/dev/mapper/eltarun-home on /home type ext4 (rw,noatime)
this gave me another idea: besides the raid-volumes differ in their type
(raid1/raid10), the raid10-volume is actually a lvm2-volume.
but since the process "[md2_raid10]" is triggering the activity, for me
it still looks like the raid is the cause. any other ideas? any way to
check why it is writing to the device?
