For some funny reasons, I'll probably have to setup a gmirror between a SCSI disk device and a IDE one, and won't have much time for testing. So I'm wondering did anyone do such a thing and are there any caveats. For example, AFAIK SCSI devices are under Giant and IDE are not - is there any reason this would make problems? -- Preserve wildlife -- pickle a squirrel today!
