Ok, the reason one gets 174 errors is due to the data coming back to the
tape process isn't an even block size amount.
This is due to the following error that RH9 spits out on the veritas binaries:
Incorrectly built binary which accesses errno or h_errno directly. Needs to be
fixed.
That gets sent across the pipe, which breaks the backups. The latest glibc
update for rh9 fixes that by putting the error on stderr but there are
other problems you'll run into there (such as bp not working correctly, etc).
I used to have a wrapper which stripped this off the output but it was
clumsy and I found a better solution.
The solution:
Make sure all the binaries have LD_ASSUME_KERNEL=2.2.5 set in their environment
before running them and everything works perfectly fine (due to the changes
in threading models between glibc releases).
So, after I install netbackup on a RH9 system (or actually RH AS/ES/WS 3.0
as it also suffers from this) I run the following: (yes there is more
efficient shell but this was quick)
# Fix for glibc-2.3 and threading
cd /usr/openv/netbackup/bin
rm bparchive
ln -s bpbackup+ bparchive+
for i in bp bpbackup bpbkar bpcd bpclimagelist bpclntcmd bpdynamicclient bphdb
bpjava-msvc bpjava-usvc bplist bpmount bprestore jbpSA jnbSA tar xbp
do
mv $i $i+
echo '#!/bin/sh' > $i
echo 'LD_ASSUME_KERNEL=2.2.5' >> $i
echo 'export LD_ASSUME_KERNEL' >> $i
echo "exec /usr/openv/netbackup/bin/${i}+ \$*" >> $i
chmod +x $i
done
cat > bparchive <<"EOF"
#!/bin/sh
LD_ASSUME_KERNEL=2.2.5
export LD_ASSUME_KERNEL
exec /usr/openv/netbackup/bin/bparchive+ $*
EOF
chmod +x bparchive
