adv_file did not recover space

Hello,

I've got an adv_file (about 10 TB). After having deleted yestarday all the savesets on this adv_file (with nsrmm -d -S), I cannot see that my volume is empty.

I've tried nsrim -X (even if an automatic runs on the night) and nsrstage -C -V, so I don't know how to get space again (this sunday, I'll need about 8 TB to make big saves...).

Here are my results (NW 8.1.1.3 under french AIX 7.1) :

# df -g /adv01

Système de fichiers    Blocs GB      Libre %Util    Iutil %Iutil Monté sur

/dev/adv01lv            9995,00    5433,10   46%      207     1% /adv01

# mminfo -avot -r "client,name,totalsize,nfiles,savetime(20),ssflags" PB152101=DADV01.001

6095:mminfo: no matches found for the query

# mminfo -avot -r "written" PB152101=DADV01.001

4779 GB

I do not want to relabel the volume because I'll lose all references to cloned savesets sourced from this volume.

Any clue/solution ?

Thanks in advance.
