There has got to be a better solution than that. I never want to consider my backups to be a first line of defense against hardware failure. I would definately create a step by step disaster recovery guide for debian software raid and make it available if anybody would find it interesting. It seems that there are many methods to set up a raid, however no one has a method to repair a raid. Sources used: http://www.tldp.org/HOWTO/Software-RAID-HOWTO-5.html debian mailing list In that spirit I have set up the following: Debian 3.1r0a IDE 1-4 each with a 2 GB and a 38 GB RAID configured using Debian software RAID tool RAID 1 = 2 GB ext3 /boot (from disks 1 & 3) RAID 1 = 2 GB swap (from disks 2 & 4) RAID 5 = 114 GB ext3 / (from disks 1,2,3,4) Results: If I replace hard drive 1 I am unable to boot. Using the grub boot disk and pointing at hd 2,0 generates the following messages: md2 No spare disk to reconstruct array! continuing in degraded mode EXT3-fs: unable to read superblock pivot_root: No such file or directory /sbin/init: 432: cannot open dev/console: No such file Kernel panic: Attempted to kill init! How do I get the OS to recognize the spare disk now, after the failure? If the RAID 1 was truly working would it have not booted? Is there another setting on my boot floppy that would help here? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
