I had a one TB RAID (Qlogic 2200 FC Copper, Chaparrel RAID, RAID3 because it wrote large files once and was subsequently read many times) which was working "ok" until today. The Qlogic Controller started reporting multiple "Phase Errors" about three days ago, but this was not logged anywhere until the whole RAID crashed this morning. A similar thing happened a few months ago with a Qlogic/Chaparrel combo attached to a Sun box (Sunfire 280R), but rebuilding the RAID via the Qlogic menus brought the filesystem back up. In this case, however, fsck reported BAD SUPERBLOCK and BAD MAGIC NUMBER. The filesystem had been used exclusively for BSD, so I was hoping that I could just re-label the disk (da0 fsize=4096, bsize=16384, bps/cpg=64)...but I still can't fsck it (no superblocks). Is there any hope for this thing?? Is there any utility to read binary bits off the partition and sensibly figure out what was on it and how it was laid out?? Qlogic does not appear to have any management utilities for Linux (or BSD)...is there any way I could have seen this coming before it crashed? -- John-David Childs (JC612) Enterprise Internet Solutions Systems Administration http://www.nterprise.net & Network Engineering 8707 E.
