Hi, I found this email adress on the website of Neil Brown at http://cgi.cse.unsw.edu/~neilb/Contact. I hope this email will find its way to the right person, within reasonable time. I installed FC3 with server installation. I'm using to identical disks 40 Gb each, no RAID controller. Disc 1 on IDE controler 1, 2 on 2. During partitioning, I did this: - deleted all partitions - created new partition on hda, file system type software RAID, 100 Mb. This will be boot partition on hda. Did the same on hdc - created new partition on hda, file system type software RAID, 512 Mb. This will be swap partition on hda. Did the same on hdc - created new partition on hda, file system type software RAID, fill to max size . This will be / partition on hda. Did the same on hdc Created RAID devices selected hda1 and hdc1 -> md1 selected hda2 and hdc2 -> md2 selected hda3 and hdc3 -> md3 copied MBR via grub When doing so, al works fine. Shutting down the system, disconnecting disc 2, and reboot. Doing cat /proc/mdstat shows only hda1/2/3, which is correct. just one minor problem: Smartd failed to load during reboot, though the smard.conf points to both hda and hdc. But the system is working OK. Shutting down again, reconnect disc 2, and reboot. Starting the server again with 2 discs. Now cat /proc/mdstat only sees this: md3-hda1 size 100000 (/boot) md2-hda3 size 38000000 (/) md1-hdc2 - hda2 size 500000 (swap) This is what bothers me. I am not familiar with the RAID1 disc recoverry procedures, and can't tell if this how it it supposed to work.When I after reboot do mdadm /dev/md3 --add /dev/hdc1, then the disk is loaded into the array. The same with mdadm /dev/md2 --add /dev/hdc3. After that, all works fine. I also tested it by removing disk 1 (primary disk), and replacing it with a brand new unformatted disk. At reboot the error showed, not bootable. so I swapped the discs, and then it worked. Another strange thing is that I configured the partitions at installation after the logical sequence, that md1 should contain hda1 and hdc1, md2 has hda2 and hdc2 etc. After installation you see that md3 has hdx1, md2 has hdx3 and md1 has hdx2... Anyway, after putting the discs back, and mdadm --add them again, things appear to be working again. BUT: What I can't find in the documentation (and I've been searching now for 3 whole days) is what to do when I replace a disk. I replaced one of the discs with a blanc unformated disk. The system boots up from the one working harddisk. Where is it written what command to execute to create an exact bootable copy on the new unformated drive. Looking forward to hear from you soon.
