--Hi *,
i got really big trouble!
My environment:
Linux 2.0.27, P133/32MB, Adaptec AHA2940, Quantum Atlas XP32150W, SCSI-Termination correct and verified! no (E)IDE-Drives nor (E)IDE-support in the kernel,
# fd says:
Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sda2 62211 26769 32229 45% / /dev/sda4 1391176 1241029 78257 94% /usr /dev/sda1 666480 574864 91616 86% /msdos
The problem:
I untarred a big archive (30MB) and deleted a big directory-tree at the same time -> boom! It trashed big parts of the filesystem.
syslog:
kernel: scsi0: Target 0 underflow - Wanted at least 98304, got 96256, residual SG count 24. . . . kernel: EXT2-fs error (device 08:04): ext2_free_blocks: Freeing blocks not in datazone - block = 543975790, count=1
Another problem:
I do a 'ls' on /msdos -> boom! I had to reset the computer.
syslog:

Isn't that funny?? ;-((
Any help appreciated!
