Verifying free disk space for partition

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. The diskValidationsMetadata.json file contains the disk partition details specifying which partitions need to be checked. If any manual configuration is required, the file is located at kyvosmanagerdata/server/userpreferences/.

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

4. When the disk space check fails due to any of the following reasons, and you still want to continue with the operation, you need to configure the value of the continueOnPartitionFreeSpaceCheckFailures property (in the Kyvos.json file) from false to true.

   1 Disk space validation file missing

   2 Partition space is insufficient for any partitions mentioned in the file.

   3 Any error in per node free disk space calculation after Step-1 and Step-2 are satisfied.
   For example,

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