Amanda users,
We have been seeing a high I/O load on one of our boxes.
One of the things noticed by one of the other admins is that
what amanda is running gzip --best in the background.
I believe that GZIP utilizes CPU and does not consume disk I/O,
also the system is sluggish during non-amanda hours points to a
more systemic problem.
However I wanted to check how things worked. I'd guess that the
data flow looks like this, with index files for the dumps.
gtar -c TEE gzip (--fast) > work area > tape
\ gzip -tf | gzip (--best) > index-file.gz
Do I have that right ?
Is there a switch for the compress type for the index files ?
Gzip is a CPU hog, doesn't use any disk I/O, does it ?
thank you,
Brian
