A UserHome directory on a Qsan NAS is used for:
1. Storing private share space for local user accounts:
Every local account created on the Qsan NAS will be automatically assigned a private folder under the UserHome directory, and shared automatically (restricted to the user's private access only, exclued Administrator access).
2. Storing necessary system debug information to be used as a important referecne for Qsan engineers' debuggin purpose, if required.
It is therefore always suggested to have the UserHome directory assigned to one of the pool in the system. Once assigned, the UserHome directory cannot be removed or re-assigned, unless the pool with UserHome directory is destroyed/removed from the system.
Since a pool is consisted of at least one physical disk, the maximum pools you may create on a system is therefore equal to the maximum number of disks you can create on the system.
For zfs (volumes and file-systems) there's no limitation on the amount of creation.
If the disk had been used on other storage systems prior to installation on the Qsan NAS, upon installation the disk may appear to be in "reserved" status.
If a disk belongs to a incomplete new pool that the Qsan NAS ZFS fails to import upon system startup, it may also appear as "reserved".
Theoratically for ZFS there's no limitation in the number of disks that can be installed on a single system. However due to hardware design limitation the maximum number of disks allowed on a Qsan NAS products is still limited.
You may create the port aggreagation with any ports, including the management port. However it is suggested that the management port should be isolated for ensurance of management interface availability.
