Am I overlooking anything? Cheers, Marc

There are issues with RAID controllers and the way they store the config data. Some store it in the controller, some in some proprietary way on the disks involved. Most of the time, the config data is non-interchangeable between different manufacturers and sometime even between the same manufacturer and different models. It's a mess. -- pi at opsec.eu +49 171 3101372 5 years to go !

If you gpart'd it first, you should be able to see your partitions, if you can't then getting a replacement controller card makes the most sense, as it's likely that the RAID card meta data is at the begining of the drive... gpart also supports the resize command...> Replying to myself again, it appears that the safest way is to get a > Rocket Raid controller identical to the one we had, put it in another > system, connect the disks, import the old pool and move the data to the > new pool on the the LSI controller. > > Am I overlooking anything?Nope... As someone else said, this is the dangers of RAID cards... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
