2023-07-20T17:06:24.529+0200 FATAL Unrecoverable error {“error”: “piecestore monitor: timed out after 1m0s while verifying writability of storage directory”, “errorVerbose”: “piecestore monitor: timed out after 1m0s while verifying writability of storage

the disk seems too slow to respond on write requests. I would suggest to defragment this disk and do not disable automatic defragmentation for this disk.
If it would not help, you may increase a writeability timeout:

Fatal Error on my Node

No And Depending on your error. For read error you may increase a readable timeout, for write error you may increase a writeable timeout. But it’s better to increase only on 30s first, so it would be storage2.monitor.verify-dir-readable-timeout: 1m30s Or storage2.monitor.verify-dir-writable-timeout: 1m30s You need to save the config after the change and restart the node.
