A script included with QuantaStor called qs-zconvert may assist you with importing a storage pool from other Open-ZFS based solutions. QuantaStor has a special naming convention for the ''storage pools'' (ZPOOLs) and ''storage volumes'' (ZVOLs) which the conversion script will take care of. Note that this command must be run from the console/ssh while logged in as root ('sudo -i').

<pre>
qs-zconvert is a helper utility for importing ZFS pools and converting them to QuantaStor naming format.
This makes it so that foreign zpools can be managed as a QuantaStor Storage Pools while retaining all
their original data.
WARNING: Please backup your data before converting. This tool has been shown to be reliable but not every
combination of ZFS to ZFSonLinux has been tested or is guaranteed to work.

Usage:

qs-zconvert list : Displays a list of all the pools available for importing
qs-zconvert listall : Displays a detailed list of all the pools available for importing
qs-zconvert import POOLNAME : Imports and converts the zpool and associated zvols into QuantaStor naming format
qs-zconvert convertvols POOLNAME : Converts just the ZVOLs to quantastor UUID format naming conventions
qs-zconvert importhg HGFILE : Creates host groups and host entries using the 'stmfadm list-hg -v' output in HGFILE
qs-zconvert importlumap LUFILE : Assigns logical units to host groups.
</pre>

Note also that if the particular features and version information for your OpenZFS system can be found by running the 'zpool upgrade -v' command. When run on QuantaStor you will see this for the feature list. If your OpenZFS based system has more features and you're using them with your zpool then you may have import problems and the qs-zconvert script may not work for you.

<pre>
