[Lustre-discuss] Bug when using /dev/cciss/c0d2 as mdt/ost

[Mag Gam]

Interesting. Just for the record, we have a P800 controller on DL380,
and we get no such problems. Running on 1.6.5

Has this problem been addressed? Because we are planning to go to
1.6.6, but I don't want to face problems like this :-)

TIA
