It is only an idea, based on something that worked for me.

And I have no direct experience with gmirror (I use gvinum on a couple of secondary systems, but those are SCSI based). Does the output of 'systat -vm' tell you anything of interest? That is, are the disks running at or close to 100%, are the CPUs fully loaded, or anything else...? -- greg byshenk - gbyshenk@byshenk.net - Leiden, NL
