Problem was solved as follow; ...... Enter full pathname of shell or RETURN for /bin/sh: <ENTER> # mount -a -t ufs # ee /etc/rc.conf Now another problem popup. At rebooting ..... /tmp not clearly dismounted /var not clearly dismounted /usr not clearly dismounted ... ... Starting syslog ... Recovering vi editor session: It hanged here. Kindly advise how to umount /tmp, /usr and /var If I need to run 'fsck' whether starting single user mode will mount / at read only. From there I can run # fsck /dev/ad4s1a (I suppose boot) # fsck /dev/ad4s1b (I suppose swap) # fsck /dev/ad4s1c (I suppose /) Kindly advise how to re-check the device, boot, swap and / TIA B.R. Stephen
