I tried to boot the instalation CD and go to console but mounting of my drives was unsuccesfull.I hoped that I will do chroot to root partition and fix the in.routed but I cannot mount drives :(

</td></tr></table>

So tell us exactly how mounting of the drive was unsuccessful. Does the OS

report any error messages while you try to mount the drive?

Tell us exactly the steps you're trying to mount the root partition and what kind of

responses you get from the system and why you think these responses are not

ok.

So I run interactive mode from the Solaris 10 installation CD and go to the console.

Btw. you are using Solaris 10 x86 (and not SPARC hardware), correct?

This is the "Solaris on x86" forum, but you never know...

When I tried to

mount /dev/rdsk/c1t2d0s6 /mnt I get is not a block device.

</td></tr></table>

Yep, /dev/rdsk/* are raw devices. Mounting a filesystem works using the

block device, which is /dev/dsk/*

Btw. are you sure that Slice #6 contains the root filesystem?

Or is slice #6 just a slice for a separate filesystem?

Convention is to use slice #0 for the root filesystem, slice #1 for swap space

(and slice #2 for all of the disk). But it is possible to ignore these

conventions and install a solaris system to use slice #6 for root.

The following command lists the available slices on the c1t2d0 disk:

prtvtoc /dev/rdsk/c1t2d0s2

Btw. if slice #6 is <b>not</b> the root filesystem but some data slice,

you can try to boot Solaris from the HDD into single user mode. To do

that, enter the boot command

b -s

at the Solaris boot prompt.

I tried also other devices like /dev/dsk/c0t0d0s1 and I get already mounted or /mnt busy.

</td></tr></table>

You can use "iostat -En" to list the installed disks.

My guess is that c0t0d0 is your CDROM device.

Unfortunatelly iostat won't list IDE disks on Solaris x86. An alternate

command is to run "format", it starts by printing a menu with the

available disks (you can press the EOF character "Ctrl-D" at this menu

to leave format).

But the disk name c1t2d0s6 is a hint that it's a scsi device that you're

trying to mount, so iostat -En should work ....

I read somewhere to start boot CD from freesbie.org and when I trie to mount I gat bad super block.

</td></tr></table>

Huh?

freesbie.org is about a FreeBSD live CD.I'm not sure if the use of a foreign

operating system is a good idea to fix Solaris OS problems. Even if they

have SunOS x86 UFS filesystem support ....

Of cause you have to boot from a Solaris CD to fix / repair a Solaris

installation.

I tried also to run in.routed again and I get error opening /etc/inet/routing.conf read-only system.

</td></tr></table>

When you have booted from the Solaris installation CD?

That won't work. When you have booted from the Solaris CD you

should mount the HDD root filesystem - for example at "/a" - and fix

the configuration files on the HDD using pathes like /a/etc/inet/routing.conf

<table border="0" align="center" width="90%" cellpadding="3" cellspacing="1"><tr><td class="SmallText"><b>Quote:</b></td></tr><tr>& lt;td class="quote">

So my question is.How can I remount the system to read-write?And what I should change to skip logging message?Is there in solaris any Interactive startup like in linux when you press "i"?

</td></tr></table>

I'd try the Solaris HDD boot with the "-s" (single user mode) option, and

if that is able to startup in single user mode, you might be able to fix the

problem from the single user mode login. You can also use boot options

"-vs" (that is, boot with: b -vs) to boot into single user mode with verbose

kernel messages.

If that does not work, you can try the Solaris CD boot, and mount the root

filesystem in read/write mode on the /a mount point, and fix the configuration

problem on the filesystem mounted under /a.
