and no more warning when you mounted it ?

if you have installed some extra package, I assume it is the folder content /opt which fills the free space so do

Code: Select all

du -sh /opt

Code: Select all

root@Cloudbox:/sda7 # du -sh /opt
18M   /opt


[Jocko]

So opt folder size is few bigger than the expected size (around 8MB) so iit is not here the issue. With a clean sda7 partition you should have around 70MB free size on sda7 but I made an error currently you check the size of the folder /opt on sda1 :pound

then repeat with

Code: Select all

du -sh /proc/1/root/opt

[antieco]

Code: Select all

root@Cloudbox:/opt # du -sh /proc/1/root/opt
22M   /proc/1/root/opt


[Jocko]

So not enough to explain your full partition. Then you have to browse the folder tree on /proc/1/root and check if you do not find some big files (~MB), for example if you had used the command wget or curl to download some files from sda7.

how do i mount sda8 i reckon thats where my files were.

[Jocko]

As you could mount sda7 without issue after rebooting the nas and according your last mount output sda8 is not again mounted, that would mean you have an issue with the fs on sda8.

So try again to mount sda8 manually

Code: Select all

mount /dev/sda8 /share/1000

and see what returns the command.
if it is not mounted, you should run a fs scan

Code: Select all

e2fsck -ny /dev/sda8

Please to note the command does nothing this time, just need to see where is the issue

[antieco]

Code: Select all

root@Cloudbox:/ # mount /dev/sda8 /share/1000
mount: /share/1000: can't read superblock on /dev/sda8.
root@Cloudbox:/ # e2fsck -ny /dev/sda8
e2fsck: symbol lookup error: e2fsck: undefined symbol: undo_io_manager

Many thanks for your help! seriously
