Greg,
Thanks for the advice. I finally found out what was wrong with my
implementation.
The mistake I had made was to assume that the partition being used by vinum was
of a special type, hence I had not gone through newfs first to create a BSD
filesystem.
Re-visiting /stand/sysinstall to create :
/dev/da0s1e from /dev/da0
/dev/da1s1e from /dev/da1
was the solution. This was the reason why the "disklable -e /dev/da0s1" would
not write the partition as typ vinum. Once I had run newfs (which created
da0s1e) I was able to change the type to "vinum"
I'm fairly certain that the orginal problem was caused not starting with fresh
partitions.
1. I now have a new problem for which I require some advice. The following
output reports that Plex ex-mirror.p1 is faulty. The volume seems to be
operating correctly but I think that the mirroring function is not happening.
Is there a simple test I can do outside the vinum command set that will confirm
this problem?
2. Assuming there is some kind of a failure in the mirroring, and that I have
repaired the problem, how do I then get the information to re-mirror onto the
newly attached disk?
Thanks again,
Tom
