Web interface and installing, updating and removing apps
I have a ReadyNAS 214 running 6.9.3 Back when it was on 6.8.0 (I think) I was one of the people who had trouble with installing and updating apps via the web interface. When the OS updated and th...
Start by running
mount --bind / /mnt
That remounts the OS partition on /mnt. The reason you do that is that it lets you see under other mount points that can get in the way.
Then enter
du -csh /mnt/*
That will give you the data stored in each in each subfolder, and give you a clue where the space is going.
My output is here:
root@NAS:/mnt# du -csh /mnt/*
0 /mnt/1
0 /mnt/apps
6.4M /mnt/bin
0 /mnt/boot
0 /mnt/data
24K /mnt/dev
11M /mnt/etc

Perhaps post your output.
So perhaps start there.
When you are done, you can undo the initial mount with
cd /
umount /mnt
Thanks. Here's the output I get:
24K /mnt/= 4.0K /mnt/1 4.0K /mnt/apps 6.2M /mnt/bin 4.0K /mnt/boot 4.0K /mnt/data 12K /mnt/dev 12M /mnt/etc 31M /mnt/frontview 0 /mnt/ftp_ban.tbl 4.0K /mnt/home 0 /mnt/homes 30M /mnt/lib 16K /mnt/lost+found 24K /mnt/media 4.0K /mnt/mnt 6.1M /mnt/opt 4.0K /mnt/proc 32K /mnt/root 4.0K /mnt/run 11M /mnt/sbin 4.0K /mnt/selinux 4.0K /mnt/srv 4.0K /mnt/sys 4.0K /mnt/syslog 588K /mnt/tmp 675M /mnt/usr 1.1G /mnt/var 1.9G total
and looking further into the /mnt/var/ (as that looks like the biggest thing), it appears to mostly be from /mnt/var/lib/clamav/
There are several large files in there, including two .tmp folders, neither of which seems to have been modified since March 2017.
You should be able to delete the tmp files. I don't use the antivirus, so my totals wouldn't include that.
Also look more in /mnt/usr, as you have about 400megabytes of stuff in there that I don't have.
My breakdown looks like

Though it's good to get this usage down, it might not resolve your original problem. It would rule out any possibility of the OS space being part of the problem though.
