I just started working on an account which is using amanda to do some of its backups of unix servers. I have one backup set where a certain Sun server fails every day with the message 'sendbackup: index tee cannot write [Broken pipe]' and there is a core dump in /tmp/amanda on the
This comes up now and then. Never found the cause/solution neither. But the good news is that nobody ever noticed a core dump, but you do! Interesting!, because up to now, I had no clue why this happened.
Can you find out which program core dumps? ("file core" would give
a clue maybe). If it is ufsrestore, then there is maybe a filename
with a strange name that makes "ufsrestore -t" dump core, breaking the
so called "index tee".If it is an amanda program, could can you stackstrace it?
A workaround is to disable the index for that filesystem. Then you got a backup at least. Then try to make an index manually using "ufsretore -t" from that backup image.
Another possibility is to locate the exact command in /tmp/amanda and run that one by hand.
There are no messages in /var/adm/messages on the client or the amanda server.
Have a look in all the debug files in /tmp/amanda too. especially in the sendbackup.* files.
