Managing Filesystems
This page describes how to view and manage filesystems using the GUI and the CLI.
Viewing Filesystems
Viewing Filesystems Using the GUI
The main Filesystems screen in the GUI contains information about the filesystems, including names, tiering status, encryption status, total capacity and used capacity.
Viewing Filesystems Using the CLI
Command: weka fs
Use this command to view information on the filesystems in the Weka system.
Adding a Filesystem
Adding a Filesystem Using the GUI
From the main filesystem/filesystem group view screen, click the Add Filesystem button at the top right-hand side of the screen. The Add Filesystem screen will be displayed.
The Create Filesystem dialog box will be displayed.
Enter the relevant parameters and click Create to create the filesystem.
Adding a Filesystem Using the CLI
Command: weka fs create
Use the following command line to add a filesystem:
weka fs create <name> <group-name> <total-capacity> [--ssd-capacity <ssd-capacity>] [--thin-provision-min-ssd <thin-provision-min-ssd>] [--thin-provision-max-ssd <thin-provision-max-ssd>] [--max-files <max-files>] [--encrypted] [--obs-name <obs-name>] [--auth-required <auth-required>]
Parameters in Command Line
Name
Type
Value
Limitations
Mandatory
Default
name
String
Name of the filesystem being created
Must be a valid name
Yes
group-name
String
Name of the filesystem group to which the new filesystem is to be connected
Must be a valid name
Yes
total-capacity
Number
Total capacity of the new filesystem
Minimum of 1GiB
Yes
ssd-capacity
Number
For tiered filesystems, this is the SSD capacity. If not specified, the filesystem is pinned to SSD
Minimum of 1GiB
No.
To set a thin provisioned filesystem the thin-provision-min-ssd attribute must be used instead.
SSD capacity will be set to total capacity
thin-provision-min-ssd
Number
For thin-provisioned filesystems, this is the minimum SSD capacity that is ensured to be always available to this filesystem
Minimum of 1GiB
No.
Must be set when defining a thin-provisioned filesystem.
thin-provision-max-ssd
Number
For thin-proviosined filesystem, this is the maximum SSD capacity the filesystem can consume
Cannot exceed the total-capacity
max-files
Number
Metadata allocation for this filesystem
Must be a valid number
No
Automatically calculated by the system based on the SSD capacity
encrypted
Boolean
Encryption of filesystem
No
No
obs-name
String
Object store name for tiering
Must be a valid name
Mandatory for tiered filesystems
auth-required
String
Determines if mounting the filesystem requires to be authenticated to Weka (weka user login)
yes or no
No
no
Note: To define an encrypted filesystem without a KMS, it is possible to use the--allow-no-kms parameter in the command. This can be useful when running POCs but should not be used in production, since the security chain is compromised when a KMS is not used.
If filesystem keys exist when adding a KMS, they are automatically re-encrypted by the KMS for any future use.
Adding a Filesystem when Thin-Provisioning in use
To create a new filesystem, the SSD space for the filesystem must be free and unprovisioned. When using thin-provisioned filesystems, that might not be the case. SSD space can be occupied for the thin-provisioned portion of other filesystems. Even if those are tiered, and data can be released (to object-store) or deleted, the SSD space can still get filled when data keeps being written or rehydrated from the object-store.
To create a new filesystem in this case, use the weka fs reserve CLI command. Once enough space is cleared from the SSD (either by releasing to object-store or explicit deletion of data), it is possible to create the new filesystem using the reserved space.tse
Editing a Filesystem
Editing an Existing Filesystem Using the GUI
Select the filesystem to be modified in the main filesystem/filesystem group view screen and click the Edit button.
The Configure Filesystem dialog box will be displayed.
Edit the existing filesystem parameters and click Configure to execute the changes.
Editing an Existing Filesystem Using the CLI
Command: weka fs update
Use the following command line to edit an existing filesystem:
weka fs update <name> [--new-name=<new-name>] [--total-capacity=<total-capacity>] [--ssd-capacity=<ssd-capacity>] [--thin-provision-min-ssd <thin-provision-min-ssd>] [--thin-provision-max-ssd <thin-provision-max-ssd>] [--max-files=<max-files>] [--auth-required=<auth-required>]
Parameters in Command Line
Name
Type
Value
Limitations
Mandatory
Default
name
String
Name of the filesystem being edited
Must be a valid name
Yes
new-name
String
New name for the filesystem
Must be a valid name
Optional
Keep unchanged
total-capacity
Number
Total capacity of the edited filesystem
Must be a valid number
Optional
Keep unchanged
ssd-capacity
Number
SSD capacity of the edited filesystem
Minimum of 1GiB
Optional
Keep unchanged
thin-provision-min-ssd
Number
For thin-provisioned filesystems, this is the minimum SSD capacity that is ensured to be always available to this filesystem
Minimum of 1GiB
Optional
thin-provision-max-ssd
Number
For thin-proviosined filesystem, this is the maximum SSD capacity the filesystem can consume
Cannot exceed the total-capacity
Optional
max-files
Number
Metadata limit for the filesystem
Must be a valid number
Optional
Keep unchanged
auth-required
String
Determines if mounting the filesystem requires to be authenticated to Weka (weka user login)
yes or no
No
no
Deleting a Filesystem
Deleting a Filesystem Using the GUI
Select the filesystem to be deleted in the main filesystem/filesystem group view screen and click the Delete button.
The Filesystem Deletion dialog box is displayed.
Confirm the filesystem deletion by typing the name of the filesystem and clicking Confirm.
Deleting a Filesystem Using the CLI
Command: weka fs delete
Use the following command line to delete a filesystem:
weka fs delete <name> [--purge-from-obs]
Parameters in Command Line
Name
Type
Value
Limitations
Mandatory
Default
name
String
Name of the filesystem to be deleted
Must be a valid name
Yes
purge-from-obs
Boolean
For a tiered filesystem, if set, all filesystem data is deleted from the object store bucket.
No
False
Note: Using purge-from-obs will remove all data from the object-store. This includes any backup data or snapshots created from this filesystem (if this filesystem has been downloaded from a snapshot of a different filesystem, it will leave the original snapshot data intact).
If any of the removed snapshots have been (or are) downloaded and used by a different filesystem, that filesystem will stop functioning correctly, data might be unavailable and errors might occur when accessing the data.
It is possible to either un-tier or migrate such a filesystem to a different object store bucket before deleting the snapshots it has downloaded.
