Managing Storage Disks with Deduplication Enabled

Managing Storage Disks with Deduplication Enabled

Adding a Dedup Sdisk

Modifying a Dedup Sdisk

Deleting a Dedup Sdisk

Quantum recommends using the StorNext GUI to manage the storage disk deduplication feature, but you can use the CLI to add, modify, or delete storage disks with deduplication enabled (Dedup Sdisk).

The fsdiskcfg command now includes a -boption to indicate that the storage disk uses blockletized storage to store data. (Blocketized storage is how this feature accomplishes space savings.)

For example, you would enter the following command to create a storage disk with deduplication enabled:

Input: fsdiskcfg -a -p /apps -b sdisk1

Before you add a dedup storage disk, you can also use the fsdiskcfg command’s -b-loptions to view a list of available locations where a dedup storage disk can be created. The correct syntax is fsdiskcfg -b-l.

(You can also use the fsdiskcfg command’s -loption (without the -boption) to view all available location where a standard storage disk can be created. The correct syntax is fsdiskcfg -l.)

You can modify the location for the dedup sdisk, but the dedup sdisk must be blank and the new location must be under the same file system.

For example, this is how you would invoke the fsdiskcfg command for sdisk1, which was previously created under /apps:

Input: fsdiskcfg -m sdisk1 -p /apps/subdir

You can delete a dedup sdisk by using the fsdiskcfg command’s -doption.

For example, this is how you would invoke the fsdiskcfg for sdisk1 that was previously created:

Input: fsdiskcfg -d sdisk1
