So, I had a system partition fail the other day, and ended up needing to completely reinstall my home server. I had a data drive was a software raid set consisting of two 120GB hard drives striped together. After making sure everything was up and running, I tried remounting the data partition. I added its configuration to/etc/raidtab, and ran raidstart /dev/md6 (raid devices 0 through 5 are the new system mirrors on my server). However this got me an error message: /dev/md6: Invalid argument Any thoughts? mkraid will wipe the disks, which is exactly what I don't want. I ran across a tool called mdadm, but when I use that in examine mode, I get this: navi(52) ~/mdadm-1.5.0> sudo mdadm -E /dev/hde1 mdadm: No super block found on /dev/hde1 (Expected magic a92b4efc, got c59ec5e0) navi(53) ~/mdadm-1.5.0> sudo mdadm -E /dev/hdf1 mdadm: No super block found on /dev/hdf1 (Expected magic a92b4efc, got 632b70d8 I *know* the drives were working properly, though for the life of me I can't remember why I didn't create them with a persistent superblock. (I think this is why mdadm is failing). -- Dan Bongert dbongert@xxxxxxxxxxxx
