Solaris 8 Boot Problems, random messages [/etc/rcS: /etc/dfs/sharetab:]

Question

Hello All,
I have all of a sudden developed issues with booting up one of my Solaris 8 [V240] Servers. Upon a routine reboot, I was faced with the following errors:
Feb 1 07:56:44 sco1-au-tci scsi: WARNING: /pci@1c,600000/scsi@2/sd@0,0 (sd0):
Feb 1 07:56:44 sco1-au-tci Error for Command: read(10) Error Level: Retryable

Feb 1 07:56:45 sco1-au-tci scsi: ASC: 0x11 (unrecovered read error), ASCQ: 0x0, FRU: 0xf
So I figured, Oh crap...the disk is messed up. However, on running a few scans, i.e. 'iostat -En' showed ALL errors to be '0'. In addition, I ran the format -> analyze -> read test which ran for about 10 or so hours and came back saying 0 errors found to be repaired. So it appears nothing particularly is wrong with my hardware. After the 2nd reboot, I didn't get the errors above anymore but now I can't seem to get past the single-user mode. I get the following errors.
mount: the state of /dev/dsk/c1t0d0s0 is not okay
and it was attempted to be mounted read/write
mount: Please run fsck and try again
/sbin/rcS: /etc/dfs/sharetab: cannot create

INIT: SINGLE USER MODE
Type control-d to proceed with normal startup,
(or give root password for system maintenance):
single-user privilege assigned to /dev/console.
Entering System Maintenance Mode
I have read a whole bunch of stuff as I found on google, like /var being full (it's not), the WWN being wrong as compared between vfstab, /dev, and /devices directory etc. I don't know what is wrong and I don't know what to do to fix this. Any ideas as to why this happened and what I can do?
PLEASE HELP!!!

Answer 1

Hi Darren,
thanks again for the response. Ok, so the question that I have right now is how do I fix my original issue pasted below:
mount: the state of /dev/dsk/c1t0d0s0 is not okay
and it was attempted to be mounted read/write
mount: Please run fsck and try again
/sbin/rcS: /etc/dfs/sharetab: cannot create
failed to open /etc/coreadm.confsyseventd: Unable to open daemon lock file '/etc/sysevent/syseventd_lock': 'Read-only file system'
INIT: Cannot create /var/adm/utmpx
INIT: failed write of utmpx entry:" "
INIT: failed write of utmpx entry:" "
INIT: SINGLE USER MODEWill running fsck fix this too? This is a critical machine and I need to bring it up during worktime in the eastern part of the world. This server has worked totally fine for over 180 days with the invalid filesystem and the inability to run fsck. Any ideas on how to fix the errors above?
Also
Yes. It needs to be at least the size of the filesystem, which you've reported to be 143349312 sectors. There's no easy way to shrink a UFS filesystem.Does this mean that that I have to re-create the partitions/layout of the disk and reinstall the OS and applications? Is there any way to re-layout without destroying the data?
Thanks
\R
