Hi,
I'm not sure to address the right person(s), the mail address is from the MAINTAINERS
list from
the linux kernel sources.
We have a linux on PC running and had some serious problems running a backup on the
scsi tape.
Maybe you can help or tell me who can.
First we sometimes had "mysterious" problems with the pc when running the backup.
Sometimes the
backup process hung and even sometimes linux hung (so I must hardware reset the
machine).
I then checked the scsi bus (termination, cable length etc.) and made some
modifications. I
also upgraded the kernel to version 2.0.36 because I heard that the aha-drivers should
be much
more stable. The scsi checklist I took from SuSE's support database.
Since then everything worked fine until one day...
The system crashed with a lot of file system errors and e2fsck was not able to repair
the file
system structure. A lot files were lost and the system could not be booted. So I had
to restore
the files from the last backup. I then immediately made the backup again and ... the
system
crashed again ... (same story). I think i did it three times until I realized that
there must
be something wrong with the tape. I could not read the tape where the backup was
stored (the
backup when the system crashed). When reading the tape the system crashed again (with
destroyed
file system). I only could read the first part of the tape but not until the end.
That's the story. I changed the tape and since then everything works fine (until the
next tape
will fail...?).
The machine configuration is:
PC with Cyrix CPU 120 Mhz, 48 MB RAM
SCSI:
Controller :Adaptec 1542 , ID=7
HDD: IBM DCAS-34330, 4 GB, ID=0
Tape: HP C1533A, ID=2
CDROM: Toshiba XM-5701TA, ID=3
ISDN: Teles S0
Network: NE2000 compatible PCI adapter
running the SuSE Linux distribution 5.2 with some partially upgrades, especially
kernel update
2.0.36.SuSE
If you have any idea what went wrong or what I can do, please tell me.
Thanks, Roland Boden
