vRanger 7.8 - Integration Guide for NetVault SmartDisk

Extending NetVault SmartDisk Storage Pools

You can extend NetVault SmartDisk physical capacity by adding or updating the volumes specified for the NetVault SmartDisk Storage Pools. Use the config ‑‑add|‑‑update ‑‑volume <path> command to extend the NetVault SmartDisk physical capacity. You can also use the following additional parameters:

 

NOTE: The NetVault SmartDisk Non-privileged User must have access to any volumes that are added to ensure that configuration changes are successfully applied.

 

Table 3. Available parameters

Config volume parameters	Description
‑‑volume <path>	Specifies the path for the file-system path of the volume to be used as a NetVault SmartDisk Storage Pool. You can specify local drives or Universal Naming Convention (UNC) paths for CIFS, NFS, and Storage Area Network (SAN). If the volume is on a mounted file system, verify that the specified path is a valid subdirectory on the mounted file system, and not the mounted directory itself. This step ensures that data is not written to the local directory if the mounted location is unavailable.
[‑‑volume-size <%>]	Specifies the percentage of the volume that NetVault SmartDisk can use; the remainder cannot be used by NetVault SmartDisk. The value of ((100 - X) / 100) * (total volume size) is added to the Last Resort Threshold (LRT). In addition, a small amount of storage is reserved to complete Garbage Collection. These three components of reserved storage determine the total storage set aside that cannot be directly used by NetVault SmartDisk. For example, if volume-size is set to 30 and the volume’s size is 100 GB, 70 GB is set aside — in addition to the LRT and Garbage Collection reserve space — and cannot be used by NetVault SmartDisk.
[‑‑dedupe-cap <Unlimited|cap>]	Specifies the maximum number of backup segments for the specific volume that can be deduplicated simultaneously. Defaults to 4.
[‑‑pool <label>]	Specifies the Label assigned to the Storage Pool. Defaults to a system-generated numeric label. Specify an existing Storage Pool label to add the volume to an existing Storage Pool, or specify a new name to create a Storage Pool.
[‑‑reservation-size <bytes>]	Specifies the number of bytes reserved by the processes streaming data into NetVault SmartDisk. A smaller size results in NetVault SmartDisk having to reserve space more frequently; a larger size renders more disk space temporarily unavailable. If the Space.Available — reported through the show option — is less than the reservation-size, the volume is considered FULL.
[‑‑favour <Staging|Storage|"Chunk Index"|"Disk Index"|All|None>]…	Specifies which Storage Pool Roles the volume is available to perform. To specify multiple roles, list the ‑‑favour parameter multiple times. For example: ‑‑favour Staging ‑‑favour "Disk Index" Use with ‑‑deny to dedicate a volume to one or more roles.
[‑‑deny <Staging|Storage|"Chunk Index"|"Disk Index"|All|None>]…	Specifies which Storage Pool Roles the volume is not available to perform. To specify multiple roles, list the ‑‑deny parameter multiple times. For example: ‑‑deny Storage ‑‑favour "Chunk Index" Use with ‑‑favour to dedicate a volume to one or more roles. NOTE: After NetVault SmartDisk uses a volume as a Chunk Index or Content Index, that is, data has been staged or stored, NetVault SmartDisk continues to use the volume for this purpose, even if this parameter is used to deny it.
[‑‑balancing <Space|Activity|None>]	Instructs NetVault SmartDisk to use the volume with either the most space available or the least activity occurring. If used with ‑‑favour and ‑‑deny, ‑‑balancing is applied last. NOTE: The --balancing parameter provides guidance to NetVault SmartDisk; the NetVault SmartDisk Disk Manager and Deduplicator make the final decision about how to allocate space.
[‑‑account <UNC-path-account>]	Required for Windows® platform when specifying UNC paths. Specifies the user account with read and write permissions to the UNC path.
[‑‑password <UNC-path-password>]	Required for Windows platform when specifying UNC paths. Specifies the password for the user account with read and write permissions to the UNC path. This password is case-sensitive.

Examples

•	To add a volume that is used for all roles, enter the following command:

…\foundation\bin\smartdisk.bat config ‑‑add ‑‑volume \mnt
\<newNetVaultSmartDiskVolume>

The NetVault SmartDisk configuration is updated.

Configuration applied

•	To add a volume dedicated to the Chunk Store, enter the following command:

…\foundation\bin\smartdisk.bat config ‑‑add ‑‑volume
c:\SDStoragePools2\Store ‑‑favour Storage ‑‑deny Staging
‑‑deny "Chunk Index" ‑‑deny "Disk Index"

The NetVault SmartDisk configuration is updated.

Configuration applied

•	To add a CIFS share, enter the following command:

…\foundation\bin\smartdisk.bat config ‑‑add ‑‑volume
\\<IPaddress>\<NetVaultSmartDiskVolume> --account <nonpriviledgedUser>
--password <nonprivilegedUserPassword>

The NetVault SmartDisk configuration is updated.

•	To review the NetVault SmartDisk configuration, enter the following command:

…\foundation\bin\smartdisk.bat config --show
