Cannot copy files to RN428 even though it shows that 700GB+ is free

I have a weird problem, hope you guys can help.   I have a ReadyNAS RN428 to which I cannot copy files even though there is apparently plenty of free space (although perhaps not as a percentage). ...

Hi Platypus69 

 

We cannot comment on whether you need to balance without seeing some BTRFS statistics first :)

 

What error are you getting when trying to transfer? Volume full or? If that is the case, then a balance will likely sort it out but I suggest getting output of the commands below and paste it into the thread, please.

 

btrfs fi sh /data
btrfs fi df /data

Then we can see what the filesystem looks like. You will need to log into to the NAS over SSH in order to run those commands. Cheers.

Thanks.

 

I am not a SSH person, so never had to do that in past with any of the RaadyNASes.

 

I am a Wintel guy, please don't shoot me... :smileywink:

 

So I have enabled SSH, but when I SSH into the RN428 I get the following error:

 

Creating directory '/home/administrator'.
Unable to create and initialize directory '/home/administrator'.

Welcome to ReadyNASOS 6.10.4

Last login: Wed Dec 23 16:20:14 2020 from p50
Could not chdir to home directory /home/administrator: No such file or directory

(BTW,  then tried by explicitly creatting a user called SSH and using that account but it to generated the same error.)

 

And if I try running the btrfs command I got the following:

 

administrator@RN428:/$ btrfs fi sh /data
-bash: btrfs: command not found
administrator@RN428:/$

So not sure if the 2 errors are related... Sorry.

 

What am I doing wrong?

 

Thanks for your patience.

 

PS:Is it easier for me to show you the btrfs log from the ZIP file you can generate?

 

PPS: Yes, getting error message that there is not enough free space, so volume full I expect. (Copying files from Windows environment.)

    Hi again

     

    I should have explained that the username to use, when accessing the command line over SSH, is root (not administrator). Anyhow, yes you can also just pull a fresh log-set and show me the btrfs.log file. That wil work too :)

      I just need to see the first two sections in that file. Essentially, everything before this line:

      === subvolume /data ===

       

      Cheers
