S12000

Error Code

S12000

Error Message

Failed to rename the checkpoint file. Refer to the errno for details. RefId: S12000

Probable Causes

This error occurs when the system fails to rename the temporary file checkpoint.tmp to checkpoint.meta. This may be due to an invalid file path or the checkpoint.tmp file being deleted.

Solutions

Troubleshoot based on the specific errno. Common issues include:

EACCES: Lack of write permissions for the old or new file path. To solve this issue, ensure that the user has write permissions for the checkpoint file and the PKEYMetaLog directory.
ENOSPC: Insufficient disk space. To solve this issue, free up disk space in time.
