Description

metastat output shows wrong replicated config/disks
after metaimport of replicated set and sometimes
getting Assertion failed if using metastat -s <setname> -c
on replicated config.
See test below:
Original set achim1 was replicated with dd copy:

I used the same config before in another test and got below output
which shows wrong metastat output for replicated set but didn't
got that assertion failed issue.
The right disks get imported but metastat states
about the older ones with old config.
Right would be seeing the same config but on
replicated drives.
