Sorry for my poor english.

Raid partition :

Personalities : [raid0]
read_ahead 1024 sectors
md0 : active raid0 hdg3[0] hde3[1]
      6326016 blocks 64k chunks

/dev/md0 have a ext3 file system formated with RH8.0.

There is a bad detection of raid device (software /dev/md0).

During the installation, disk druid don't detect the ext3 file system in
/dev/md0. Disk Druid give the "foreign" type and not "ext3".

If you don't recreate the md0 device you can't format /dev/md0 and the
installation abort with :

Error :
An error accured trying to format md0. This problem is serious, and the install
cannot continue.

Other message from another console :
mke2fs :
Device size reported to be zero. Invalide partition specified, or partition
table wasn't reread after running fdisk, due to a modified partition being buzy
and in use. You may need to reboot to re-read your partition table.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install Phoebe in a system with a raid device (software)
2. Run manual partition with Disk Druid

Actual Results:  Disk Druid don't detect the ext3 file system.

Expected Results:  Disk Druid should detect the ext3 file system.

Additional info:

Here is some kernel message that can help (perhaps there is some mistake !).

I also have some problems with RH8.0 and raid device but don't invertigate.

Comment 2 Féliciano Matias 2002-12-29 17:36:56 UTC
I do one install with hard disk mode (text mode) and don't see this bug.

Comment 3 FRLinux 2002-12-31 12:49:32 UTC
I saw the same behavior where phoebe was unable to correctly detect my raid0
partition. I wasn't installing on it though as i had /dev/hda6 free for this.
But that's only after a kernel recompilation that i could access my data on
/dev/md0, before it kept telling me that it wasn't an ext3 fs.

Here's my partitionning :
