All,
First I'd like to express my appreciation to this list and all who replied
/ read my novice ramblings and pleas for help. All responses were a real
pick me up while I was in despair.
[sorry if this is long winded]
Ok now to the fix...
It really boiled down to the damn fifo and my lack of understanding them.
Unfortunately I'm not the kind of person who can read a manual and readily
grasp it's concepts, I'm more of "lets do it first and see what happens"
type of guy.
I never did figure out how to restore just the tar file w/o using a fifo.
All config variations kept giving the same behaviour. I could watch the
Storage Daemon read the Bacula volume and I saw where Bacula created the
named pipe "file". The process wasn't putting the streaming data into the
pipe. While I could not find where the data type was set, I agree that
FT_FIFO type must have been the cause of this stubborn behaviour. Very
frustrating...
So I was schooled by one a senior developer at work on named pipes,
un-named pipes, and fifo behaviour. Now the words in the manual made a
little more sense.
So it starts in the ClientRunBeforeJob in the MailRestore.bash script. The
previous admin used fifo and set up the job just like the instructions
said. Specifically opening a named pipe with the mkfifo cmd then running a
tar xpf of that named pipe. This put the Bacula backup job back in the
original directory. Since I didn't have the original dir my efforts in
relocating the data and just getting a "tar" file were folly. Recall I
changed 2 things in the Bacula restore, restore client and location. This
was needed because the original location was no longer available.
The restore was looking for a process reading from the fifo [as was
suggested by Martin]
2 changes were needed in the MailRestore.bash. 1) [this was probably not
really needed but done anyway] Modified a path statement to match what was
changed when I mod'd the restore option in the Bacula restore. 2) [the
biggie] replaced the "tar xpf" line with a "cat > mail.tar" line
[Original] tar -xpf ${fifoDir}/mail.tar </dev/null &
[New] cat ${fifoDir}/mail.tar > mail1.tar 2> mail1.err </dev/null &
This worked!! I now have my data in a tar file. Yes, I've extracted the
contents and all looks good.
Thank you again for all the comments and help. I'm sure I'll be back with
more adventures.
Respectfully,
--Kenny
