Subject: Workstation problems
Date: Tue, 06 Aug 91 22:00:15 EDT
From: Thomas H. Grayson <tgrayson@ATHENA.MIT.EDU>
Our workstation ("mustang", Room 1-151), is now failing to present the
normal login screen. It displays the messages:
XIO: fatal IO error 32 (Broken pipe) on X server "(null)"
after 0 requests (0 known processed) with 0 events remaining.
The connection was probably broken by a server shutdown or KillClient.
dm: Xlogin failed to become ready
Unable to start xlogin, doing console login instead.
It then displays a console login prompt.
I shutdown the workstation, and did an fsck, expecting it to produce
errors as it normally does. It produced a number of unusual errors including
an excessive bad blocks error, plus long list of "spare fields of inode
contained values I=xxx" were xxx had values 8760 through 8831. This took
a while to get through.
The file /etc/athena/popd was reported bad and removed. The directories
/etc/popd, /mit/1.00, and /u1 were corrupted. The inode count in the
superblock was wrong, and the cylinder groups were bad.
When I tried to reboot the system, the startup script failed when
setting the hostname, reporting the error: "Network routing: pid 46 (route)
was killed on unaligned access, at pc 0x40e97c". It hung for about a
minute while setting the time, then reported losing contact with three
volume location servers, and couldn't attach the system libraries.
The machine then fails to start Xlogin, as before.
I suspect that the disk corruption I feared due to the overlap of the
boot and swap partitions has occurred. I should note that I modified
/etc/fstab to include an additional swap device on rz1b and also
changed /etc/rc.conf and /etc/inetd.conf to provide remote access to
the workstation.
Since the machine no longer boots properly, it needs attention.
Please help.
