Any errors in the messages file? I might want to do a
'format,analyze,read' on the LUN just to verify that it's okay.

Then I'd capture the output of 'metastat -p'. Next I'd reboot and see
if the metadevice would come up properly when initialized.

If not, I'd be tempted to destroy the devices (metaclear) and recreate
them in the exact same order (helped by the metastat -p output).
Creating concat/stripes, one way mirrors, and soft partitions should not
affect underlying data. Creating raid 5 will zero storage unless you
also use the -k option.

I'd probably want to make sure I had a good backup before doing that.
