.
To reactivate Snap EDR functionality after creating a new volume, download the
Snap EDR package from the SnapServer web site and install it on the server using
the OS Update feature. Then click the
Snap EDR link in the Site Map (under Extras)
and click the
Start button.
Note If the volume on which the NVDB directory, antivirus software, or Snap EDR
resides is deleted, the system attempts to move the items to another volume with
the most available space. If no other volumes are available, the items are
automatically disabled.
Note If you delete a volume, you will also delete any iSCSI disks that reside on that
volume.
Expanding Volume Capacity
A volume’s capacity can be expanded by navigating to the Storage > Volumes screen
and clicking the name of a volume. There are two ways to expand the size of a
volume:
• Adding Unallocated Capacity — If there is unallocated capacity remaining on the
RAID, you can add this capacity to the volume by editing the Volume size field
or clicking the
Grow to Max. Size button, and then clicking OK.
• Creating a New RAID — If all capacity on the RAID is allocated, and either: (1) a
sufficient number of drives to create a new RAID exists, or (2) a RAID of the same
type with excess capacity exists, the
Expand Volume button appears. Click this
button to create an additional RAID, group the RAID with the existing RAID, and
expand the volume into the space on the new RAID.
Note If you expand the volume onto an existing RAID with existing volumes,
those volumes will be preserved and the expanded volume will only consume
the free space on the RAID.
A volume can be expanded up to 16 TBs, either as a standalone volume or as a
volume group.
Security Models, SnapTrees, and Volumes
Volumes are created with the Windows security model (which can be changed in
the
Securities > SnapTrees page or when creating a share to point to the volume
root). Directories created in the root of a volume (aka SnapTree directories) in the
Web UI are automatically assigned either a Windows- or a UNIX-style security
model, based on the security model of the parent volume (this can also be
subsequently changed in the SnapTrees page or when creating a share pointing to
