Hello,
My name is Jason. I have been off and on this list for a few years now.
I have just compiled and installed 3.3.2 on my system. I am having trouble
getting taper to work.
When I ran amdump, the system began to correctly pull the data from the
sources, and filling up the holding disk. The output of amstatus always said:
"taper status: Searching for a new tape"
I can use "amtape <config> label" to load tapes from the changer just fine. I
can even use dd to/from the tape drive to verify the correct tape is present.
The output of "amcheck <config> -t" shows:
Amanda Tape Server Host Check
-----------------------------
amcheck-device: Taper::Scan did not quit at
/usr/lib/perl5/site_perl/5.8.8/Amanda/Taper/Scan.pm line 303.
Server check took 0.155 seconds
(brought to you by Amanda 3.3.2)
I have a dell 2750 system with a dell tl4000 tape library, and two LTO4 drives.
For what it's worth, I am backing up a lustre partition mounted on the amanda
server via infiniband. I am using Whamcloud's modified gnu tar to do the
backups. Total storage to backup is 17 terabytes.
Here is my amanda.conf file so you can see my changer definitions:
