 Posted: Thu Feb 19, 2004 4:47 pm Post subject: Parted not working properly under 2.6.3 |
 |
|
Using gentoo-dev-sources-2.6.3, parted gives me the wrong geometry for disks, eg:
| Code: | gentoo root # parted /dev/hdb
GNU Parted 1.6.6
...
Using /dev/ide/host0/bus0/target1/lun0/disc
Error: The partition table on /dev/ide/host0/bus0/target1/lun0/disc is inconsistent. There are many reasons why this might be the case. However, the most likely reason is that Linux detected the BIOS geometry for /dev/ide/host0/bus0/target1/lun0/disc incorrectly. GNU Parted suspects the real geometry should be 7299/255/63 (not 116336/16/63).

Booting with 2.4.x there's no problem.
Anybody else getting this? |

try toggling the auto detect geometry option in the kernel config. someone reported that they needed it to get past the dreaded "2.6 VFS unable to mount root" kernel panic
Which suggests that it may operate differently from 2.4.
A bit of a shot in the dark, I'll grant you, but worth a try I suspect

It looks like it might be a problem with parted interacting with the kernel - fdisk and cfdisk are fine:
| Code: | gentoo root # fdisk -l /dev/hdb
Disk /dev/hdb: 60.0 GB, 60040544256 bytes
255 heads, 63 sectors/track, 7299 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I noticed this a while back, and got well and truly confused into the bargain. Then I solved the problem that I was trying to address using parted and forgot about it...
that's rather worrying, that it...
