Hello,
after a crash (hardware failure) of an OST with two lustre partitions one
partition (/dev/sdb) cannot be remounted after restart.
The second (/dev/sdc) partition mounts fine.
What needs to be done in such a case ?

I dont see any hardware issues.
Could this be caused by extremely high load? I'm seeing up to 300 load on a
dual processor quad
I just realized that I may not have answered your question, and I'm
not sure if the patch is in the source posted at sun.com or not.
If not, it is in the bug as an attachment -

The disks are DDN S2A 9550.
I didnt see any issues on the hardware side. And my IO tests finished
fine which was using all of the OST. Could long IO wait cause an error
like that?
I'v seen the OSS load hit 300 on a IO stress test.

I have a system thats been spitting out OST disconnect messages under
heavy load. I'm guessing the OST eventually reconnects.
I want to say this happens when the OSS is extremely overloaded but I
did notice this happening even under light load. Only the OSS seems to
spit out any error messages.

Yes, let simplify our test environment.
- i have 2 lvs routers (one active router and one backup router used for
failover) to balance connections through our servers located behind them.
