I've looked online and through the sunmanagers archives for solutions to my
problem but have to admit that I'm still puzzled.
I have an Ultra 5 running as a server. It's running Solaris 2.6 and has an
Ultra Wide SCSI card. On one channel I have a DLT tape drive. On the other
channel I have 2 9GB hard drives. They been up and running without fail
since 1998. Recently one of the filesystems began to give me
trouble. Lots of error messages like: /filesystem bad dir ino 2 at offset
242 : mangled entry. Running fsck (yes I did unmount it) on it would find
lots of unknown file type I=# Clear? errors. Originally fsck fixed it but I
wasn't comfortable that all files were still connected. Within a few
minutes another fsck revealed more errors so I decided to newfs and restore
from tape. The filesystem was residing on one of the disks in a 4GB
partition with one other 4GB parition and a 500 mb partition. Neither of
the other filesystems was complaining. Still I had an emtpy 4GB parition
on the second drive so I moved the filesystem over there. I issued the
newfs command and restored the data from tape and ran fsck after the
restore, it was fine. Now here we are less than 1 week later and I'm
getting the same mangled entry errors. Still none of the other filesystems
are complaining. Ideas on what could be causing this? Ideas I saw on the
web were overlapping partitions or bad SCSI cable. Here's the partition
info from the format command, I'm just showing the relevant slices....
0 0-3716
2 0-7498
4 3716-7432
As far as I'm aware those cylinders don't overlap. I haven't tried chaning
SCSI cables yet. I'm thinking that may not be the issue because wouldn't
the other filesystems be reporting errors also?
I hope I haven't left out any relevant information. Will summarize. TIA
for any help.
Lisa
