OpenSolaris Fails to Start

[mgh21]

Hello,

My OpenSolaris system, which I have been running for quite some time, has stopped working. It gets as far as the splash screen with opensolaris, and the bar that goes from left to right. If I press ESC, I can get to a text login screen, and can log in. One thing I note here, is that /export/home is not mounted.
I have a Sony Vaio VGN-BX295VP. There does not seem to be a hardware problem, as I am currently using it having booted off the OpenSolaris CD, and it is running happily like this.

Any ideas?

Have You tried to use some other/older Boot Environment? (assuming that You created any)

Thanks, but, no I don´t have any. (Trying to install updates always fails on this system.)

It does seem to be using c8d0p0 as the root disc. Does anyone know how I can find out what part of this it would use as the home directory?
When I run fsck on /dev/dsk/c8d0s0 1 or 2, it tells me bad super block at 16: magic number wrong.
/etc/vfstabs tells me nothing about physical device names.

Thank-you for the command.

It tells me:

* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 2 00 16065 195302205 195318269
2 5 01 0 195318270 195318269
8 1 01 0 16065 16064

Which, I think, means that everything is in one partition on the disc, so my home directory must have been in there somewhere, but I cannot find it now.

The output doesn't look correct because under the Mount column you should have "/" for the 0 (zero) partition. Partition 2 is the whole disk.

If you had separate filesystems, say /opt on slice (partition) 3, then under the Mount column would be /opt and so on for each separate slice and filesystem. Looks like /home was a directory under / because there is only one slice (partition) which is 0 (zero).
