When trying to add a state replica using metatool to cylinder 0 of a disk, the following error message appears:
Your attempt to attach metastate database replicas on slice "c?t?d?s?" failed for the following reason: Slice c?t?d?s? is too small to contain 1 replicas.
This is because metatool masks out the very first cylinder to protect the disk label. On disksuite v4.1, metatool does allow adding the databases to cylinder 0 on 2.1Gbyte disks or larger.
As a workaround, start at cylinder 1 (not cylinder 0) or use the command line (metadb -a).
