Thanks to all who replied. The consensus is that although the first
defragcron to hit a domain should lock it and prevent any mischief,
you should only defragcron a domain from one host at once. There was
an honorable mention for using vfast instead, but I think that's only
available on 5.1B.

Subject: defragcron on CFS volumes

Hi all
A quick question about defragcron. By default (if you uncomment it) it
will defrag all mounted AdvFS (presumably including CFS) volumes. My
question is: if you have a two-node cluster with shared CFS volumes on
an EVA, should you allow defragcron to run on both systems or just one;
if on both, is there a chance that both hosts will try and defrag the
same volume at once and get confused? We are running 5.1APK4.
Thanks
John
