MyCloudEX4 Saying out of Space

So I have had my MyCloud EX4 for a couple of years without any problems. Now in the last few weeks it wont let me save to one of the disks claiming its out of disk space when there is 410GB free. I have read a few posts and have restored the system as i thought it may be the root partition full, but its not changed anything. I have managed to login via SSH (I’m a newb to linux). I have ran a DF which returns this:

root@WDMyCloudEX4 /root # df

/dev/sdc2 2925145912 2705311760 190573608 93% /mnt/HD/HD_c2

To me it looks like there is a problem with " /usr/local/modules" what is this and how can i resolve it?

I want to try and avoid restoring the whole system as i have a lot of data, that i don’t really fancy copying back and setting things up again.

Thanks

i believe it depends on the volume you are trying to copy .

Say take for example the last line of result states its 93% full. not sure if its quota specifc.

But if you are copying more then 7 % which could be multiple GB’s or MB’s

Try the same with small files say 10-100 Mb’s and see if the issue persist.

Also give it a try to copy same set HD b4 & C4 which is only 2% consumptions.

I do agree you might have 400 gig free space. It depends on how did you setup the RAID or JBOD.

if you care to share the actual setup like RAID and storage of Each bay which will give some insight on what might be happening there.

@Jon-W Check your inodes

df -i

It’s any file or folder that will not allow creation on that disk. The other two disks are fine at present.

All of the disks are setup in JBOB.

I will try this when i get home thank you.

So here is the results of df -i

root@WDMyCloudEX4 root # df -i

/dev/sdc2 2857600 43866 2813734 2% /mnt/HD/HD_c2

Does this help to find where the problem is?

Can anyone shed some more light on my issue?

As nothing has changed and i’m still unable to save :frowning:

You’re out of inodes on /dev/sda2 which is only 55% filled to capacity.
There’s a KBA that will help. As always, backup before troubleshooting or changing anything is always a best practice.
