so i set up a raid5 software array using mdadm. (i am new to it). on ubuntu 7.10. it's got 4 devices total. it looked to be up and running becuase during boot i got: raid5: raid level 5 set md0 active with 3 out of 4 devices, algorithm 2 and then df -h yielded a drive mounted in the correct mount point with free space showing of the size of 3 times the size of a single drive. so to test it i pulled a drive out. there were a number of notifications. so i re-booted after the notifications stopped. then when i reboot though, with the pulled drive put back in, it won't re-build or come back. instead i get this error during the boot sequence: ext3-fs: unable to read superblock mount: wrong fs type.... so do you know what steps one takes to get the array built back up? did i lose all the data? (if yes, it's ok, just a test... but that would seem to defeat the purpose of raid5. should i have done something different?) thanks, gt
