Hi,
I have a server with RAID1 partitions with linux 2.4.1 (stock,
self-compiled) installed.
It was easy to create the RAID partitions but when booting, no
auto-detection is successful.
The kernel says that autodetect is running, then done, but nothing is
auto-detected.
My devices are IDE devices (hda + hdc) and all drivers are bult-ins (no
initrd nor modules).
After the boot, making a raidstart works like a charm...
Any advice?
Help welcomed.
Thanks

Sounds like you didn't set the partition type to be "FD" which is what
the raid autodetect looks for. (Read the Software-RAID howto). I
did the same thing yesterday. :)

---------------------------------------------
4.10 Autodetection
Autodetection allows the RAID devices to be automatically recognized by the kernel at boot-time, right after the ordinary partition detection is done.
This requires several things:
* You need autodetection support in the kernel. Check this
* You must have created the RAID devices using persistent-superblock
* The partition-types of the devices used in the RAID must be set to 0xFD (use fdisk and set the type to ``fd'')
---------------------------------------------
I guess you forgot to mark the partitions as type 0xfd. I have a similar box
here with 2.4.1 and autodetect works like a charm.
Cheers,
