Partition free space check for upgrade, patch, and rollback

You can configure the free space requirement for all the required partitions. Disk partitions free space check is performed in cluster operations, such as cluster deployment, Kyvos upgrade, patch deployment, and rollback.

Points to know

1. You can configure and specify the free space requirement for all the required partitions.

2. Disk partitions free space check is performed while deploying cluster, Kyvos Upgrade, Kyvos Patch Deploy & Kyvos Rollback.

3. The diskValidationsMetadata.json file contains the disk partition details specifying which partitions need to be checked is located at kyvosmanagerdata/server/userpreferences/.

4. The configuration is hot deployable, which means after file upload from KM UI in all applicable operations where this disk partition check is involved, the newly applied changes in the file will be considered.

5. If the disk partition check fails—meaning the required amount of free space on the partitions, as specified in the diskValidationsMetadata.json file, is unavailable—you can still continue with the operation. The process will not fail; instead, it will change the value of the key in the Kyvos.json file from continueOnPartitionFreeSpaceCheckFailures from false to true. This key determines whether the operation proceeds even if the partition disk check fails.
   For example,

   {
   "partitions": {
   "/var": { "freeSpace": "2G", "type": "absolute" },
   "/run": { "freeSpace": "96", "type": "percent" }
   }
   }

To upload the diskValidationsMetadata.json configuration file, perform the following steps.

1. On the navigation pane, click Utilities > Manage Configuration Files.

2. On the Manage Configuration Files page, click to expand the kyvosmanagerdata/server/userpreferences/ folder.

3. Click the file that you want to update and click the corresponding Upload button.

   

3. Click the Choose File button to locate the configuration file from your computer network, and click the Upload button.

   

4. Click the Save button from the top-right of the screen.
