Dear all, please help!
I added those two servers again, and again the job dumps all DLEs to holding
disk, but fails to write those two DLEs to tape!
Just to make it clear:
I was backing up a server called Minerva, and all seemed well.
I added two more servers, callled Apollo and Cerberus. Then some of
Minerva's DLEs failed to write to tape after dumped to the holding disk.
I remove Apollo and Cerberus, and the backup works ok.
I add Apollo and Cerberus again, and again Minerva's DLEs dump ok, but fail
to write to tape.
This time I ejected the tape, and tried to amflush to the next amanda tape.
Amanda told me that I needed to run amcleanup. So I ran amcleanup and then
ran amflush again. Amflush then sent me an email saying there were no files
to flush!
So I rebooted the server again, and now amflush works.
What on earth is going on??
Please help!
