I am using 5.1.2 and a Tr4 10/20 gb IDE tape.

It responds to "/bin/mt -rewind" etc.

However when I run the /sbin/e-smithj/backup

it does not seem to complete the backup, and I get:

and when I follow Darrell's howto to list the files, it gives me:

Any ideas?

I tried "newtape" (as per an earlier posting), and also Darrell's tip to force the erase.

'Filesystems = ' is not good  This should read 'Filesystems = / /boot'.  Check the templated /etc/flexbackup.conf file for template/output errors.

Darrell

many thanks, the flexbackup.conf file had

filesystem[0] = ''

in it.

I editted it, and the backup whent through, am about to restore it on 5.5 now.

If I run the command manually it works.
(dump -0 -b 10 -a -f - / | gzip -4) | buffer -m 3m -s 10k -u 100 -t -p 75 -B \
|  -o /dev/nst0

If I run the script "backup", the buffer writer fails.  Any ideas?

Try running it again without removing and re-inserting the tape. If it works (and I suspect it will), it seems to be a problem I've been having. It's been reported as a bug to the developers (at Mitel).

I tried running the command twice, same behavior.....

Here is what I see in the /var/log/messages file.....

Aug 16 17:03:31 ns kernel: st0: Error with sense data: [valid=0] Info fld=0x0, Current st09:00: sense key Illegal Request

No, but let'd find out. Run this command:

/sbin/strace -f -o/tmp/backup /sbin/e-smith/backup

and then send /tmp/backup to bugs@e-smith.com, along with your explanation above as to what the problem is, and a description of what you have done.

Thanks

Charlie,

I ran the trace as you suggested and sent the tracefile to bugs@esmith but haven't heard anything from them.

Do you know who might have looked into this?

[Gernot Temmel]

I have exactly the same problem as John Phillips. If u get any information on the problem plz post it here, cause I have no idea what to do.
