Managing Storage Disks with Deduplication Enabled
StorNext User’s Guide 338
Managing Storage Disks with Deduplication EnabledQuantum 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).
Adding a Dedup Sdisk 2The fsdiskcfg command now includes a -b option 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 -l options 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 -l option (without the -b
option) to view all available location where a standard storage disk can
be created. The correct syntax is fsdiskcfg -l.)
Modifying a Dedup
Sdisk 2You 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
Deleting a Dedup Sdisk 2You can delete a dedup sdisk by using the fsdiskcfg command’s -d
option.
For example, this is how you would invoke the fsdiskcfg for sdisk1 that
was previously created:
Input: fsdiskcfg -d sdisk1
