SYS$EXPREG fails when executing DFG V2.9 on a large volume

[Nicolau Roca]

OpenVMS V7.3-2

We have a large volume of 200 GB called disk$usr1, and the free space is about 30 GB (about 15% of the total size)

We use DFG (Disk File Optimizer) V2.9 to defragment it at night, but after a few hours the script fails with the message:

%DFG-F-SYSSRVERR, call to system service SYS$EXPREG failed
-SYSTEM-F-ILLPAGCNT, illegal page count parameter

The same message appears when we issue the command

defrag show disk$usr1/volume

We changed the value of the logical name DFG$PGFLQUOTA to 65536000 to avoid insufficient virtual memory errors, with no results at all

Any ideas?

Thank you

looks like a bug so report it if you can.

Did you look at the process to see if the process was running with the increased quota.

[Jan van den Ende]

I agree with Ian.


Looks like somehow the pagcounter overflowed.

Should however be able to deal with up to 1 TB, I would assume.

Enter a formal bug report, if you are on support.

Proost.

Have one on me.
