hard-disk changed from sda to hda

Caranthir · 2007-10-05 12:23:38

Hi all,
i have a two ide drives that are usually named hda and hdb and 2 usb external drives named sda and sdb, with ArchLinux those drive are all seen as sda, sdb, sdc, sdd.
The problem is that when i recmpile the kernel thay come back to hda/hdb and i must rename /etc/fstab to make it works; now can anyone tell me why with the default kernel those drives are all mapped to sda/sdb?
I don't know what kernel option is enabled...

I'm just guessing, but look for IDE SCSI emulation in your self-compiled kernel options... possibly it is the ide-scsi module. Otherwise it may be a udev issue.

Don't know the option name - all I know is that some kernel releases ago IDE drives moved to a new "architecture" called libata, common with SATA. If it's enabled, they're sdX, if they use a legacy option, it's hdX.

Similarly, if you use ide hook in mkinitcpio, IDE drives are seen as hdX, if you use pata, it's sdX.

You can set persisten block device names, then it doesn't matter what you use: http://wiki.archlinux.org/index.php/Per … ice_naming

I'll enable it later, right now i recompiling the kernel, maybe i've found what options i've to enable

see you later and thanks for the quick answers

Ok, i enabled the experimental support for libata under Device drivers and unchecked ide support, now with the custom kernel i have my ide drives named sda/sdb

I receive e few errors when installing the kernel (btw the PKGBUILD i use is the default one, i took it with abs):

loading package data... done.
checking dependencies... done.
cleaning up... done.
checking for file conflicts... done.

done.

the BusLogic module is not compiled at all, i don't know why the script looks for it but i can enable in the next kernel
the modules pata_sis anda ata_generic and compiled statically in the kernel so ofc they aren't present as modules but they're enabled anyway...
don't know about the find errors onestly, ck is the localversion of the kernel but all modules are in /lib/modules/2.6.22
In the /etc/mkinitcpio.conf i've this line:

MODULES="pata_sis ata_generic"

that is probably causing this problem, it looks for these modules but ofc they can't be found
That said the script install the modules in pkg/lib/modules/2.6.22 instead of pkg/lib/modules/2.6.22-ck (as it should?), plus when i install the kernel it creates a initrd image that i don't use, the kernel starts even without it so i can remove it?
