Object storage was mounted on the KV node. Today, we found that the backup failed. Later, we discovered that a large number of files in the deleted state had filled up the system file count. Why did this happen?

cosfs is a tool for mounting object storage to a server.

Submit a ticket to Tencent. The mounting is stuck.
