Cant clear disk space

[orhayun]

Hi,
I deleted old data to clear some dick space, but still when i connect to the administration portal i see the disk space hasn't changed.
Also from the server no matter what i delete, the disk space would not change.
I tried to restart the qnap but no luck. I took control on this qnap from previous owner.
Any help?

That stupid pie-chart only gets updated once per day. (It's useless information if it isn't "real-time" data).

You can check diskspace from the command line of the NAS. Access your NAS via SSH, login as "admin" and run:

Code: Select all

df -h | grep -v qpkg

For example from my NAS:

Code: Select all

df -h | grep -v qpkg

After you've deleted some data (and emptied the recycle bin if you have it enabled) - go to "Shared Folders" and click the green refresh button for each share. This will update the size column and the pie chart immediately.

If you do it at the command line, it is always "real time" data. Yes you have a choice, you can continue to do it the hard way if you can't handle the command line.

Why stuff around with a command line when there's a nice GUI.

Why stuff around with a command line when there's a nice GUI.

Because it is faster, more informative, and usually provides "useful" errors if something is wrong. Also WebUI's change over time but the underlying commands typically stay the same. I've been using "df -h" for over 25 years. UNIX, Xenix, and Linux all support this command. I suspect that OS X probably supports it too.

Windows users can install Cygwin on their machines if they want the same functionality.

Ok thank you very mush guys very helpful stuff.

df -h | grep -v qpkg

Just plain "df" is enough on my system (I don't have any packages installed so I don't need to exclude those from the listing, and the "-h" option appears to do nothing).

Code: Select all

df --help
BusyBox v1.01 (2015.01.25-18:18+0000) multi-call binary

Usage: df [-hmkc] [FILESYSTEM ...]

Print the filesystem space used and space available.

Options:
	-c	correct formatting error

	-h	print sizes in human readable format (e.g., 1K 243M 2G )
	-m	print sizes in megabytes
	-k	print sizes in kilobytes(default)

Must default to human readable format then - here's the output from "df" :

Code: Select all

Quite possible. It is Busybox, rather than the "real" GNU version of "df", so anything is possible. I wish QNAP would eradicate Busybox from the Firmware completely. Busybox makes sense on small embedded Linux devices with very little storage, for example Routers, but it is useless to provide it on Storage devices that usually have terabytes of available storage, and can therefore support the "real" binaries.
