[PlanetCCRMA] basic rescue help

[Jose Francisco Neto]

Hi Odeb and Fernando,

I faced a problem similar to that some time ago.
If for any reason your hda4 was formely defined as ext3 and your machine
crashed, after a fsck you may loose the journal of the partition. If it's the
case, change your fstab entry to ext2 and your system will start ok.

I hope it helps. Send us some good news.

Best regards,

You are right, that seems to be fine.

What is the content of your /etc/fstab? There could be a mismatch there,
I guess. Does the system start to boot? At what point do you get the
error?

I don't think that should make a difference. It can be changed by fdisk,
I can't remember now the command.
