drbd-0.7.19 under kernel 2.6.17-rc4 is running on a primary node 
standalone. There are 8 resources in the same group. fsck.ext3 -fv is 
being run simultaneously on all of them. Each of the drbd devices are 
running on an lv, which all belong to a single pv. The actual "disk" 
is a hardware RAID connected via SCSI (i.e., the mpt driver).

Five of the fsck finished their tasks successfully and reported no 
problems. The remaining three got "stuck". There was no activity 
either on the physical RAID itself or listed in top. They were just 
listed as "D," uninterruptible sleep. Two of the fscks were at the 
end, giving the final summary information--no problems---for their 
respective filesystems and were stuck at that point. The last one was 
stuck in the first pass. Attempts to kill them failed; even kill -9 
and attempting to shutdown were ignored. I rebooted manually and ran 
the three stuck ones again without a hitch.
