Failed to delete volume because it has one or more clones

Recently I had this issue with AWS FSx, where I was not able to delete some of the volumes, and in the UI it showed me this message

Failed to delete volume because it has one or more clones. Delete or split the clones and try again.

Long story short, I had to login into the Netapp admin console, and delete them from there, but I had another issue, I was not able to split the clone, as their parent volume have been deleted.

Try to split a clone, as it was not online

FsxId05190788adb5c91a6::> volume clone split start -vserver svm1 -flexclone trident_pvc_50f52487_1e3d_4c54_963f_cdc07db73b57_1033 

Error: command failed: Volume trident_pvc_50f52487_1e3d_4c54_963f_cdc07db73b57_1033 is not online. It needs to be online for this operation.

Try to bring the volume back online fails, as it queued for delete.

FsxId05190788adb5c91a6::> vol modify -volume trident_pvc_50f52487_1e3d_4c54_963f_cdc07db73b57_1033 -state online

Error: command failed: This operation is not supported on a volume of type "DEL".

What eventually worked for me was to restore all deleted volumes first, and you need to be in privileged mode to do that,

FsxId05190788adb5c91a6::> set -privilege advanced
FsxId05190788adb5c91a6::*> vol recovery-queue recover-all 

Bring them online, and then you should be able to split them

Once you are done, the clone list should be empty,

FsxId05190788adb5c91a6::*> vol clone show
This table is currently empty.

And you SHOULD be able to delete all the volumes normally.
