- Well, I'm not sure, but these are my experiences:
-
- 1) At one occasion, what I experienced was exactly the same as what Art
- mentions above (except that WP was not involved). I could boot from CD,
- though. The filesystem was OK. So I replaced the boot block
- (please use extreme care while doing this!) and everything worked OK.
-
- 2) At another occasion, my system came to a halt with this series of
- messages:
-
- Jan 19 01:33:36 dutiea mach: 1667329652, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block 1667329652, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block 1652571184, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block 1652571184, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block -32567613, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block -32567613, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block -2082471937, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block -2082471937, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block -134217729, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block -134217729, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block -32, <3>/: bad block
- Jan 19 01:33:36 dutiea mach: bad block -32, ino 84993
- Jan 19 01:33:36 dutiea mach: bad block -1987, <3>/: bad block
- Jan 19 01:33:39 dutiea syslogd: going down on signal 15
-
- No booting possible, of course. The filessystem was a pretty mess,
- too. After manually fsck'ing still no boot. After replacing the kernel
- (no message about corruptness od /sdmach given by fsck!) it booted, but
- not immediately: an exception #2 arose. But after typing "b" the system
- booted normally. Power-off, power-on - again exception #2. Very simple
- explanation: in the process of trying everything I turned "boot
- diagnostics" boot option on. Since there are no diagnostics to boot, the
- boot process gives this exception.
-
- On both occasions, the only part of the system I could blame, is the
- disk. Is there any possibility of checking the disk for bad blocks? Or
- could it be the faulty internal SCSI connection? I feel rather
- incomfortable with this.
-
- Has anybody experienced the same symptoms?
