I have LVM on DRBD and DRBD is on the /dev/md2 RAID1 system

 device minor 1;
                disk /dev/md2;
                address IP:7788;
                meta-disk internal;



There was  temporary out of space on / partition and then we got this errors

How we can fix this now ?
Can I run fsck on  /dev/drbd1 ?
