Hi *SM'ers,

I'm facing a strange problem, and would like to know if somebody could give me 
an explanation ...
The picture :
We had a policy domain, named "NT" defined for Windows systems,  that got only 
one mgmt class, called NT-SYSTEMS, copy group looking like that :
NT ACTIVE NT-SYSTEM STANDARD 15 15 30 60, pointing to a disk pool called 
diskpool_win.
I then was required to initiate new backups, for Microsoft SQL DB's. I thought 
it would not be necessary to create a new policy domain to do those backups, 
and just added new management classes and copy pools, looking like :
NT ACTIVE MGMT-SQL-FULL  STANDARD 6 0 No Limit No Limit, pointing directly to a 
tape pool called tapelto_sql_full, used for SQL full backups
NT ACTIVE MGMT-SQL-LOG  STANDARD 1 0 No Limit No Limit , pointing to a disk 
pool named diskpool_sql_logs, size 4 GB, used for SQL log backups
NT ACTIVE MGMT-SQL-META  STANDARD 6 0 No Limit No Limit, pointing to a disk 
pool named diskpool_sql_meta, size 1MB, used for SQL meta data
I activated, and validated the whole stuff, and next night, got all my NT nodes 
having backup status "failed". After some headscratching, I found my problem 
was due to the fact that all directory data was sent to diskpool_sql_meta, 
which was too small, and had no migration pool. So far I agreed : directory 
data had took the management class having the longest retention period.
I then built a new disk storage pool, named diskpool_dir, size 4 GB, attached 
to a new Mgmt class looking like : 
NT ACTIVE MGMT-DIR STANDARD 15 15 No Limit No limit

And also defined a new client option set for NT nodes, specifying "DIRMC 
MGMT-DIR". Once again activated the whole thing, and had 3 peaceful nights ... 
until today.
The event logger showed me some NT nodes had status "failed" for their backup, 
reason : "no space available". I then found that diskpool_meta was once again 
full, because those nodes had written directories path into it ! But that time 
I really can't understand what happened. 
Does anybody have a clue what  happens here ? 
Zillion thanks in advance !
Arnaud
