Hey Amanda Specialists,

I've setup Amanda with Virtual Tapes on a 600GB LVM Volume on Fedora Core 11.

We want to backup mostly Windows Clients. The Amanda Client is installed on the machines.

Now I did notice, that bigger archives do not backup.

The biggest directory I could backup until now is a little bigger than 3GB.

I need to dump directories with up to 60GB and they just don't start, neither gave any errors. Neither I did find anything in the logs.

Some input would be gladly appreciated.

Peter

Well, finally I did found in a log where the problem supposed to be:

These directories with a bigger size, fail due to the following error:
'Can't switch to degraded mode when using a new disk'

Ok.. seems Amanda cannot switch to a new VTape or something...

Now I did decrease the tapecycle to 1 tape and now I'm able to dump a 6.6GB directory which did not work with tapecycle 20 tapes.

I have in amanda.conf

dumpcycle 4 weeks
runspercycle 20
tapecycle 25 tapes

With this Amanda gives an error in amcheck:

changer error: slot <error>: Slot 8 is already in use by drive '/home/amanda/diario/drive0'
(expecting a new tape)

And with this configuration I cannot backup directories with 6.6GB or more...

So I left

dumpcycle 4 weeks
runspercycle 20
tapecycle 1 tapes

And amcheck gives now a Warning: tapecycle (1) <= runspercycle (20), but I can dump the bigger directories..

I'm actually a little confused....

And help is still apreciated!

OK:


'Can't switch to degraded mode when using a new disk'


This means that the DLE is brand new, and for some reason Amanda is trying to go into degraded mode, which means it wants to do incrementals. You can't do an incremental of a new DLE.

This is a bug - delete the drive0 directory (which only contains a symlink)
