Hi everybody,

I'm using Networker on a Linux RHEL 5.3

Oracle's Archive logs are backuped on an adv_file device which is a nfs share mounted on my Networker server and pointing on a NAS share.

This adv_file device is only dedicated to oracle archive logs, pool name is ArchiveLog.

When I extract via mminfo the lsit of all savesets located on this adv_file device and calcultes the total size of these savesets, I find a real difference with the disk space usage reported in Networker Media / Volume screen and also with the result of a df command typed on my server, OS side.

Here are figures :

The sum on  savesets recorded on my adv_file device is 70Gb

(obtained with mminfo and calculated within excel - I did not find a faster way to calculate it, sorry : mminfo -q "pool=ArchiveLog" -r "name,space,savetime,space,volretent,space,sumsize" | awk '{print $1";"$2";"$3";"$4";"$5}' > mminfo.csv)

In the Networker Media / Volume screen, the adv_file device is said to have 99Gb used

df -h command tells me that there is 95Gb used over a 150Gb total on the nfs mount.

Why is there such a difference ?

Is it an index purpose ?

Does Networker allocates fixed size blocks with a "x" size, even if datas to be written is 10 times smaller than "x" ?

As the filesystem was nearly full I had to increase the quota on this FS.

I ask the question to know if this behaviour is a normal networker behavior, before increasing the FS space.

Thanks for your reply.
