[MooseFS-Users] Chunkserver failed to start after reinstallation

[<18...@gm...>]

Hi, I have 1 chunkserver in the cluster need to be reinstalled, and
after configured it, chunkserver can't start

# /etc/init.d/moosefs-chunkserver start
Starting moosefs-chunkserver:
open files limit has been set to: 16384
working directory: /var/lib/mfs
lockfile created and locked

with defined meta id (file: '/mnt/sdb/.metaid') - use '!' in drive
definition to ignore this (dangerous)
hdd space manager: chunkserver without meta id shouldn't use drive

definition to ignore this (dangerous)
hdd space manager: no hdd space defined in /etc/mfs/mfshdd.cfg file
init: hdd space manager failed !!!
error occured during initialization - exiting

Its working mfs disks were mounted

# mount /dev/sdb1 /mnt/sdb
# mount /dev/sdc1 /mnt/sdc

All mfs data disks were untouched, only remounted lastly.

How can I solve this error?
Thanks in advance.
