Re: [cobalt-users] raq 4 raid failure



I may be wrong, but the two hard drives are not the same size and thus should not be able to mirror. Please correct me if I am wrong. I also know from other posts that the original hard drive is no longer available. What are we to do? (No joke) Do we have to pull the good drive and copy it to another drive with something like drivecopy and then put two identical drives back in the Raq????

At 10:57 PM 11/20/2001, you wrote:
After replacing the primary drive on a Raq4 raid array the GUI continues to
report
the raid drive failure with a flashing red alert. Anyway to clear this?
It's been over 48 hours and I beleive the drive is now formated and
mirroring again.

Heres the results of cat /proc/mdstat:
