I'm confused, my list of unanswered questions so far: - if the HPT 374 driver shows up as scsi devices (which is possible, I do not know anything about this driver), why do the promise drives start with hde and not hda? - what do you mean by "Won't be found", but finds them at bootup and can be accessed with cfdisk? are they there or not? check with hdparm -i /dev/hdX what does pvscan check (verify with strace)? I once had a problem with some HPT controller where the driver insisted to have two different devices, one for each disc, and another for some hw-raid configuration, unfortunately the lvm pvscan checked only the hw-raid discs not the raw discs for physical volumes ... Here is what I would recommend (in your case): get a recent vanilla kernel with highpoint 374, promise ata 100 tx2 _and_ recent devfs support (maybe the ide patch is required, to support the hpt controller), configure and build this kernel according to your (minimal) requirements, then boot with this kernel and have a look at the devfs mount (you do not have to mount it at /dev, but it would be advantageous to do so ..) you should now be able to actually see which drives are 'found' and available, if some drives are missing, your driver configuration isn't what it should be, or one of your controllers isn't supported ... hth, Herbert > > regards > /Carl Philip > > _________________________________________________________________ > The new MSN 8: advanced junk mail protection and 2 months FREE* > http://join.msn.com/?page=features/junkmail > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
