Hi TSM-ers!
If I issue the command q occ KL10FE1F TSM returns the following
occupancy for filespace /var:

Node Name       Type    Filespace       FSID    Storage         Number
of      Physical        Logical
                        Name                    Pool Name       Files
Space           Space
        
Occupied        Occupied
        
(MB)            (MB)
----------              ----    ----------              -----
----------              ---------               ---------
---------
KL10FE1F        Bkup    /var            43      DL_LBU1 27,100
1,050,203       1,049,884

However, when I issue a q filespace KL10FE1F /var TSM  returns:

Node Name       Filespace       FSID    Platform        Filespace
Is Files-               Capacity        Pct
                Name                                    Type
pace            (MB)            Util
        
Unicode?
--------------- -----------             ----    --------
---------               ---------               --------
-----
KL10FE1F        /var            43      Linux86         EXT3
No              2,015.8         43.5

This node is backed up daily (1 time per day), incremental only and data
is kept for 7 days.
Let's assume 100% of the data in /var changes daily, the maximum amount
of data in TSM should be 7 * 2 Gb. (size of /var) = 14 Gb.
So why does TSM say that 1 Tb. of data is stored for /var?
The problem is I don't know how to check this. The TSM database table
BACKUPS contains the filename of the backed up files, while the size is
kept in the OBJECT table if I'm correct.
Thank you very much for any reply in advance!
Kind regards,
Eric van Loon
