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. If the disk partition check fails, this indicates 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" }
   }
   }
