Question 1:

How do I turn off paging in De-Frag/X?
Answer:
Interactive runs of De-Frag/X paginate output, approximately every 22 lines. At the end of each "page," De-Frag/X prompts to continue. A "/" will terminate the current command, and a dash "-" will turn off paging for the rest of that command.
Question 2:
How long does the jdefragx job take?
Answer:
This really depends on the percentage of free space you are starting with. If the free space for a disk is greater than 45%, then you can expect 30-45 minutes for the job to run on that disk. If your free space is less than 45%, then give yourself between 45-75 minutes to run for that disk.
Question 3:
What is the sysxtnts file?
Answer:
This is a Temporary Work File left behind by fscheck.mpexl.telesup due to a bug in fscheck. This bug will be fixed in the 6.5 version of fscheck. This file should be purged after each run of fscheck.
Question 4:
I have an older version of DEFRAG/X - are there any problems I should be aware of?
Answer:

The deflog.pub.sys file in versions B.05c and B.06f fills up. Versions B.07k and later will mend this. Supported De-Frag/X users should update to this version. An alternative fix is to add a purge statement before the run command in the jdefragx job. The statement will look like:

!purge deflog.pub.sys

This file will then be rebuilt as necessary.Contact your account manager at (541) 812-7600 for update information, or email support@lund.com for help with updating the jdefragx job.

Question 5:
When you are running disk mirroring, what happens when you run a defrag against a file? Does it defrag both locations of the file?
Answer:
De-Frag/X only has to do the primary, the mirroring software/hardware will take care of the operation on the secondaries.
