[Zope] Safe way to abort or re-start stalled out ZODB pack?

[John Schinnerer]

Hello,

This is for

Zope 2.9.8-final, python 2.4.4, linux2 (debian)
(installed by the Plone 2.5.5 installer if that matters, and using 
zeoserver)

I have a ZODB pack operation started via the ZMI control panel that has 
failed to complete. It appears to be from a disk space issue (traceback 
below).

The zope instance is still working fine on the pre-pack ZODB, and, there 
is a Data.fs.pack file sitting in ../zeocluster/server/var which hasn't 
been modified in the last ten hours.

I need to know how to deal with this situation safely - how to abort 
and/or safely re-start the pack (the disk space issue has been dealt with).
Some questions that have come to mind are:
Is it safe to just restart zope?
Will that clear the stalled pack operation automagically?
Will I need to do something manually with the Data.fs.pack file?

Any assistance appreciated...!
thanks,
John S.
