Re: tar backup ok but restore errors w/ scsi dat dds2
so try to copy stuff to tape, again ...
find /home/ralph | buffer | tar zcvf /dev/st0 -T -
should sound nice and smooth .. no stopping and starting
- it should be a constant and steady whine
I think I've exhausted my resources attacking this from the software
Will do a little mobo swap and see what happens.
yeah.. but first get the tar command and buffer right...
than spend some dough on a better mb, but no guarantee to fix
the original problem
- get a new tape cleaner and new tape
- try a different tape drive
- make sure you have enough cpu hp
- make sure yu have enough memory
- ( top -i ) should be almost no load while writing to tapes
Ok, but only cause you asked all nice like :)
I tried it one more time...
Cleaned the drive with a new cleaning cart and used a new tape.
I was the only user logged on the box and top -i showed CPU 99.7% idle
Running a Celeron 2.4GHz w/ 512MB RAM
Ran the tar through buffer:
shinzon:~# find /usr/kbmosas/std | buffer | tar zcvf /dev/st0 -T -
tar: Removing leading `/' from member names
Backed up 110 files, 1.2MB without any errors from tar
ok, now read the tape back:
shinzon:~# tar tzvf /dev/st0
drwxrws--- root/users 0 2005-08-25 10:10:35 usr/kbmosas/std/
-rw-rw---- root/users 7516 2005-08-25 10:31:52 usr/kbmosas/std/_amort
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
gzip: stdin: invalid compressed data--format violated
tar: Child died with signal 13
tar: Error exit delayed from previous errors
I have already tried two different tape drives (seagate/sony), different
tapes, cleaned the drive repeatedly, flashed bios on scsi with latest ver,
updated tar to 1.15.1-2, and now tried buffer(ing). Tested writing/reading
tar ball to hd with no problem. And there is the fact that if I put this
scsi card and either tape drive in another box (tried two other 1- SCO Unix
on a 486DX266 and 2- Debian Linux on a PII in testing), they work fine.
This all leads me to think that the problem is the environment (mobo). Maybe
this particular combination of mobo/scsi?
I'll let you know what happens.
