Description gerald.ehritz 2001-03-05 16:22:36 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.2.16-22 i686)

The promise fasttrack 66 controller seems to be recognised by the kernel,
but diskdruid or fdisk only shows the physical parameters of the first
drive in a definded raid 0 array. Booting after install is not possible,
lilo hangs after displaying LI

Reproducible: Always
Steps to Reproduce:
1. plug in a promise fasttrack 66 controller, setup a raid 0, install dos
on a small partition on it.
2. install fisher, look at the wrong raid 0 parameter
3. boot after install

Actual Results:  Booting Linux not possible

Expected Results:  Linux should have booted 

At boot time kernel shows some infos about the chip set on the fasttrack
66, which looks ok. Seems that the controlelr is not asked about existing
raid arrays.

Comment 1 Arjan van de Ven 2001-03-05 16:52:35 UTC
This is a "fake software raid" card. Promise refuses to give specs for it,
but drivers on the first cable work fine. Drives on the second cable are
invisible for now, I'm working on fixing that.

But it means you cannot mix linux with that other OS for now.

Comment 2 gerald.ehritz 2001-03-07 07:26:00 UTC
If promise refuses to give out the specs to the public why do FreeBSD seems to
have it? Did a test with a fasttrack 100 today and it works perfectly with
FreeBSD 4.2 and recognises the existing raid 0 array and the 2 drives connected
to the second chanel!

There are drivers avail from promise, but onhly for RH 6.2 and 7.0. Do somebody
know if this drivers will work in the next RH release ( 7.1?).

Comment 3 Arjan van de Ven 2001-03-07 09:44:07 UTC
If the driver is binary only, it will not work unless Promise update it. We
won't ship it in this case.
If it is GPL'd and open source, I would not mind having a look at it.

Comment 4 Arjan van de Ven 2001-03-07 10:14:04 UTC
More info: Our kernel will find the second drive just fine.
I'm looking into the bsd driver to see if there enough information there to
make linux support it.

Comment 5 Arjan van de Ven 2001-03-23 14:58:40 UTC
Using the existing RAID0 is not doable in a reasonable timeframe.
Although the needed information is there, there is a very dangerous
interaction with setups where people ignored the "RAID" and used linux
to just install partitions on the drives. There is no safe way to detect
if it is a "Windows RAID" or a "Linux drive" yet. Development will continue,
but doing it properly will take some time.

Comment 6 gerald.ehritz 2001-03-26 10:44:56 UTC
FreeBSD uses different devices for disk and raid on this controller and does not
allow to use a drive in both.
