- Hello,
-
- I am having some problems getting my Sun IPC (SunOS 4.1.1) up
- and running after some changes I did not think would give me a
- problem. Here is what I did...
-
- o A friend of mine brought over a scsi-cd from his next. I wanted
- to try it out on my standalone and because I had no device to
- device cable I had to remove my shoebox (internal 669 and tape)
- and only have the cd attached. Before I shutdown I removed the
- entries in /etc/fstab corresponding to the filesystems on the
- 669 (/usr/local /usr/spool/news). I commented them out...
-
- o I tried to boot with the cd attached and didnt see it during the
- boot process (not to worry, it was no big deal, I just wanted
- to see if I could get access to it). But the boot did not
- complete. It gets as far as the ldconfig and then complains
- with the following errors
-
- ldconfig: directory /usr/openwin/lib not cached
- ^^^^^^^^^^^^
- link from /usr/local/openwin
- link editor directory cache
- /etc/rc: 81 Memory fault - core dump
- [...bunch more Memory faults]
-
- squid init:'/usr/etc/getty std 9600 consol' failing,sleeping
-
- o So after some thought I realize that it is probably not
- building the ld.cache. When I boot -s, single user, I can
- run echo *, rcp, tar... the other staticlly linked commands
- but I get the same error when I try to run anything else.
-
- o I tar'ed a copy of fstab to diskette, took it to a friends and
- removed the comments for the 669's fs and then tried to put it
- back in /etc on my machine. BUT! it came back and said the fs /
- was read only?!?!?
- mount shows /dev/sd0a rw ?!?!
-
- o When I boot from the monitor I issue b -s and then fill in the
- prompts when it asks me for devices to boot from, and swap from.
-
- Why cant I write to / when I boot in single user? If I could do
- that Im sure that restoring fstab should fix the original problems.
- Are the filesystems permission problems related to the fact that
- rc cannot complete any commandsI
- Can anyone offer any insight into how I can restore fstab. Getting a
- bootable tape is not really an option since I dont have close access
- to anyone that I could get one from.
-
- Thanks in advance, Paul
