TNAS 5 Out of Disk Space - Delete 1-2 Terabytes and still says disk fill

[bbezanson]

I have a TNAS F4-220 running TOS 5.1.123.

A few months ago I did the backup and complete reformat to get the 8GB partition for 5.x properly set up and things have been "OK".

So my issue today is that I was using tools to pull down some data for my Plex and I ended up filling up the disks.

My system has 4 - 4 TB Drives with ~10.89 TB for my main Volume.

I have tried cleaning up space of the disk to no avail.
- I delete a Time Machine backup that was 1.4 TB in size, but the "df" command doesn't show any free space.
- I did the "empty trash" for all shared folders and even deleted the recycle option.
- I then proceeded to delete via the File Manager another 400 GB of files.
- I SSH'ed into the system and deleted files that way (another 200 GB) and still, I don't see any freed up space.

I have restarted the TNAS twice now. This last time the restart failed and I had to hold down the power button to get it to shut off and then started and I'm logged back in now -- but still showing the disk as full.

Code: Select all

df -h
Filesystem           Size  Used Avail Use% Mounted on
/dev/md9             7.5G  1.8G  5.4G  25% /

tmpfs                1.9G  352K  1.9G   1% /run
tmpfs                1.9G  4.2M  1.9G   1% /opt/var
/dev/mapper/vg0-lv0   11T   11T   64K 100% /Volume1
cgroup               1.9G     0  1.9G   0% /sys/fs/cgroup

In the File Manager I get Properties for each of my Shared Folders

Code: Select all

Music - 85.25 GB
Photo - 64.13 GB
public - 1.34 TB
Plex - 13.34 GB
Video - 0 (no size, no files, no directories)

Video of course is the Share that filled up the disk. It should show ~10.25 TB used.

What are the ways to fix this?

- Any command/utility to fix the issue for that Share Volume?
- Am I stuck trying to manually cp the directories I want to keep (like Home_Videos) to my backup @USB drive and then deleting the Shared Folder? Guess I should set a limit on that Shared Directory.

Thanks in advance for any/all help.

Sorry on the Heading, should say "still says disk full"

[bbezanson]

I was thinking the "Properties" issue on the Video Shared Folder might be leading to something, but the Time Machine file I deleted was on the public Share and that was ~1.3 TB is size.

Rita in Tech Support was great.

We deleted the Snapshots -- I had 100 that were configured. This freed up 80 GB or so.

Then I turned off Snapshots completely and now have 2.32 TB free.

We will see where things go from here.
