If someone is interested. This online translation. Sorry.
I did not mean for LVM to add the new HDD.
But we do know that the Samba share.
In my solution is:
The installation of a HDD.
The HDD has seen sdb1.
1, and the primary partition is created.
Then I recorded the /etc/fstab
/dev/sdb1 /var/lib/nethserver/ibay/sdb1 auto defaults,acl,user_xattr 0 0
That works for me without problems.
