No Checkdisk Filesystem possible on QNAP

[georg.strauch]

With version 4.4, it is up to an QNAP TS-221 (ARM) not possible, to make a "file system check", for example after a power failure. Trying breaks with the error message "Unmount Disk not possible by Asset UPNP". To disable Asset and system restart does not help, only after a complete uninstall the program the CheckDisk does works completely
