cifs.smb2.durable_handle.timeout This option determines the length of time that open files are preserved for disconnected clients. During this time, a client can reconnect and reclaim the files. After this time has passed, the open files are closed. By default, the specified duration value is in seconds, and can be specified with an optional s character suffix. To specify minutes (m) or hours (h) instead, append an m or h character to the duration value. Specify -1 to preserve open files indefinitely.
