[9fans] Fs64 file server, partition boundaries out of range, and `Tvirgo' tag

[Gregory Pavelcak <g.pavelcak@comcast.net>]

I've been trying to replace some IDE disks, currently serving as
mirrored worm in my fs64 file server, with some 50G Seagate scsi
drives.  After doing a copydev and changing the config to make use of
the scsi drives, I see two problems.  First, early in the boot
process, I get (I'm not actually sure about the numbers, I have a very
messy hand written note here)

cannot add sd12!plan9 [63,156296385] to disk [0,976937355): partition
boundaries out of range
cannot add sd13!plan9 [63,156296385] to disk [0,976937355): partition
boundaries out of range

These are the 2 drives I'm trying to add.

Then  later, it appears that the server is going to come up, but I get

tag=Tnone/0; expected Tvirgo/6105775 - flushed (6105775)
panic:fworm:checktag 6105775
cpu 0 exiting

I don't know if these two things are related.

Appreciate any help.
