[Dump-users] Verify with -Mf stalls asking for next tape

[Kenneth P. <sh...@se...>]

I'm doing a multi-file dump (-B 1000000 -Mf) to an external USB drive. I 
then do a verify (restore -C) to check the backup. My last verify stopped 
with this prompt:

You have read volumes: 2, 3, 4, 5, 6
Specify next volume # (none if no more volumes): 7
resync restore, skipped 230 blocks

Normally I run this from a script at midnight Saturday, so the prompt fails 
the backup with no input. Here I ran the verify by hand from a shell window 
and was able to let it continue by entering the next file number.

It would be nice if the operation would continue without prompting in this 
situation, reading until no more files were available.

What would cause restore with -Mf to prompt like this?

BLOCKING=64
MAXMISCOMPARES=10000
SIZE=1000000
DUMPSUBDIR=/mnt/Backup/0

$DUMP 0u -h 0 -b $BLOCKING  -Mf $DUMPSUBDIR/root/dump \
 -Q $DUMPSUBDIR/root/qfa -B $SIZE /

/bin/mount -o remount,noatime /
$RESTORE -C -l -L $MAXMISCOMPARES -b $BLOCKING -Mf $DUMPSUBDIR/root/dump
/bin/mount -o remount,atime /
