Comment 2 RHEL Program Management 2008-01-14 09:57:09 UTC
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.

Comment 4 Zhang Kexin 2008-02-22 12:41:25 UTC
because has no such hardware: Server has internal 1-TB array on 3w_xxxx
controller (/dev/sdb), and large (> 1-TB)external fibre-channel array on an LSI
fibre-channel controller, so verified by code review.

Comment 6 Bryn M. Reeves 2008-02-26 14:19:46 UTC
There's no need for any special hardware - see Milan's reproducer in comment #13
of bug 179201:

Simple reproducible only with dmsetup - maybe need some change, depends on
memory conditions:

dmsetup create m1 --table "0 100000000 zero"
dmsetup create m2 --table "0 100000000 zero"
dmsetup create fm <<EOF
0 10000000 zero
10000000 33333333 mirror core 2 1024 nosync 2 /dev/mapper/m1 0 /dev/mapper/m2 0
EOF

dd if=/dev/zero of=/dev/mapper/fm seek=43333000
