OK, you've got a syslog. That's excellent. The question is: Did you reboot between changing the partition layout and creating the filesystem? Anyway, my suggestion would have been to run gpart. > Why it can happen when replacing two partitions with large one? Because (c)fdisk modifies the partition table that's on the disk. The kernel uses a different in-RAM copy of that partition table -- usually in the state it's been at boot time. Fdisk actually tries to let the kernel reload the partition table -- but this often fails. Only a reboot synchronizes the kernel's cached copy of the partition table with the "real" one that's been written to disk. So your new partition table is only valid after a reboot. fdisk actually issues a warning about this, I'm not sure about cfdisk. Why it is talking about accessing "sdb1" and mounting it as ext3 -- I dunno. Maybe some major partition layout inconsistency? > I tried gpart with this output: > ----------------------------------------------------------------------- > #gpart /dev/sdb > Begin scan... > Possible partition(Windows NT/W2K FS), size(40959mb), offset(0mb) > Possible partition(Linux ext2), size(197512mb), offset(40959mb) > End scan. Bene, bene, excellent! So it seems to be true, the linux partition is still hiding on that disk at offset 40959MB. > Primary partition(2) > type: 131(0x83)(Linux ext2 filesystem) > size: 197512mb #s(404505360) s(83885760-488391119) > chs: (1023/239/63)-(1023/239/63)d (5548/0/1)-(32300/239/63)r If you have some free spare space on another disk, try to dd that partition into a file and loop-mount it. E.g. $ dd if=/dev/sdb of=/elsewhere/ext3fs bs=$(expr 83885760 / 197512) skip=83885760 count=$(expr 488391119 - 83885760) $ mount -o loop /elsewhere/ext3fs /mnt/test Otherwise, you have to try and create a valid partition entry for that "hidden" partition. gpart can do that too, AFAIK. But I prefer the "backup" way I outlined above. -hwh -- gentoo-user@gentoo.org mailing list
