Hi, I installed two QUANTUM Atlas III 9 GB disks, using RAID 1 on a REDHAT 5.2 (right out of the box - no patches installed). Apart from the fact that I had to add the alias line to /etc/conf.modules manually (alias md-personality-3 raid1). Once mounted, my system ran proprely, testing writes and reads of various files. Wanting to be prepared for disaster, I disconnected the power of the second disk in the RAID array and performed a read on some files in my mounted raid directory. That started o.k., upto a point where my cat stopped reading the file. When I rebooted the system (with the second disk powered again) , raidrun -a exited with a 1, suggesting I should run ckraid. Amazing: ckraid reported no errors, and the correct block count. But: NO GO. (btw, I ran ckraid with a collection of possible options...) /proc/mdtab reported a VERY large number of blocks - larger than the correct number as reported by ckraid. fsck didn't help either - did report a clean filesystem !!! ???. I am feeling like a fool right now (reading despretely every doc - again ...) Can somebody help me with info/suggestions ? Thanks to the entire linux community. Hope I can contribute something usefull myself (in the future). Best regards.
