Hi David, thank you for your reply!I've tried putting it to /etc/fstab, but getting the error on boot time. And since it's remote computer, it's a little inconvenient cause it won't continue the bootup process without keyboard input. Here is my fstab setup:
/dev/hda1 / ext3 errors=remount-ro 0 1 /dev/hda2 none swap sw 0 0 /dev/hda3 /mnt/hda3 ext3 defaults 0 2 /dev/md0 /mnt/md0 ext3 defaults 0 0 (this commented out for boot) proc /proc proc defaults 0 0 /dev/fd0 /floppy auto user,noauto 0 0 /dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
When I build the raid with mdadm --create, do mkfs.ext3 and then do mount (with or without -t, doesn't matter) it mounts beautifully. When I reboot, uncomment the device in fstab and do mount -a or just try mounting it via mount -t ext3 /dev/md0 /mnt/md0 it gives the error.
I've also tried doing "dd if=/dev/zero of=/dev/hdc" to make it clean. When doing e2fsck /dev/hdc1 I get this error:
e2fsck 1.35-WIP (07-Dec-2003) e2fsck: Invalid argument while trying to open /dev/hdc1 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblockis corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Many thanks for any input!!
Timo

Ihad Redhat9 installed previously on the same machine (with working software raid setup), but I'm now moving to Debian. My kernel is 2.4.18-bf2.4 and has support for RAID1, which I'm trying to create. I'm following these instructions (thank you Lucas for excellent instructions!): http://www.cs.montana.edu/faq/faqw.admin.py? query=1.22&querytype=simple&casefold=yes&req=search All goes well up to point 8 (I'm able to create raid, put ext3 filesystem on it and even mount it). But that's only the first mount. After reboot, when trying to mount, I get this error message: "mount: wrong fs type, bad option, bad superblock on /dev/md0, or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?)" I've tried zeroing the superblock, with no help. Also tried recreating the partitions (times x) and tried recreating filesystem.How are you mounting it? If you are mounting using an explicit: mount -text3 /dev/md0 /mnt, but have not modified your /etc/fstab correctly (thats the file that is used at boot-time to decide where and with what options filesystems are to be mounted), then this behavior would make perfect sense. -davidc
