Description Stephen Walton 2000-08-23 18:53:21 EDT
My Redhat 6.1 system contained two IDE disks, hda and hdc, set up as a
RAID-0 system, and a single SCSI disk with the OS on it.  While attempting
an update to RedHat 6.2, the installation procedure attempted to mount both
/dev/hda5 and /dev/hdc5 as normal ext2 file systems.  This failed, but in
the process the RAID system was marked as unclean, requiring a lengthy fsck
on first boot.  Fortunately no data were lost, but I doubt this can be
guaranteed.  I'd think the tool which attempts to mount a file system
should be changed so as to not to touch the disk if there is not a usable
ext2 file system on it.

What are the partition types for these partitions - they should be type 0xfd.

Also - are these partitions listed in your /etc/fstab? They should not be if
they are part of a RAID array.
Comment 2 Michael Fulbright 2000-08-24 10:08:49 EDT
May be related to bug number 16832.
Comment 3 Stephen Walton 2000-08-24 17:46:58 EDT
(hanging head in shame) No, the partitions aren't type 0xfd, they're type 83.  I
was _sure_ I'd set them to 0xfd when I created the RAID array, since I carefully
followed the instructions in the HOW-TO, but obviously I forgot a crucial "w" to
fdisk at some point.  /dev/hda and /dev/hdc are not listed in /etc/fstab,

Will any harm be done if I unmount the filesystem, change the partition type on
both disks to 0xfd, and remount it?
Comment 4 Michael Fulbright 2000-09-07 16:50:55 EDT
I would backup your important data before changing the partition types. I think
it should work but don't hold me to that.
