I have Solaris 10 Express that I installed on a PC with two drives. It was on drive 1 (with the boot drive being drive 0). Linux was in a different parition and my boot options where managed by grub.

The Solaris parition's /etc/vfstab referenced the root, user, etc.. disks as c0d1sX. But since I remove the original boot drive, the new disk has become d0. So naturally when I attempt to boot Solaris it craps out.

I can boot single user, but / gets mounted read-only and therefore I cannot change /etc/vfstab.

The CDROM drive doesn't work, so I'm left with few options.

Is it possible to get the root filesystem mounted rw so I can edit the /etc/vfstab?

If so, how?

Thanks.

boot from CD in single use mode, then manually mount c0d0sX to /mnt, and edit /mnt/etc/vfstab

Any other alternatives?

see if you can remount root:

then edit vfstab directly.

If you have another system you can plug the harddisk to it and mount it with -o rw and edit your vfstab.

I'll try the "remount" option first. Thanks.

I do have a system that'll boot Linux and FreeBSD. But under Linux I can't mount the Solaris partitions writable.

And I haven't figured out how to mount them at all under FreeBSD. It doesn't seem to like the type "ufs".
