Volume full full with 4TB free
I have a ReadyNas 3130 with 4 3TB drives. Recently my back up application stated to fail because it could not write to the storage drive indicating that the drive was full. Under the system tab of the device, the data indicator shows that there was 4TB free of 8.17 TB but the log files indicated that the device was at 90% of its storage capacity, so what gives. I had to delete some of my backup data in order to write to the device. I upgrade the firmware to 6.6.1 and I guess I will have to wait to see if that fixes the problem. Is there something in the setting that I am missing or is this a known issue. I have 4 3TB drives (ST3000NM0033) in the device, Raid 5, X-Raid.

If Antivirus is still enabled, please disable and reboot. Hopefully it gets better then.

Re: Volume full full with 4TB free
Which backup application? Some wrongly configured application may back up the data to the OS volume, which is 4GB of capacity.
How much data do you in this specific backup? (If it's more than 4GB, it means that's not the problem).
Can you download the logs from the GUI and paste here the beginning of the btrfs.log please?

The backup software is MSP backup and recovery. The backups are being stored in the correct location. The log files ave been cleared

Re: Volume full full with 4TB free
btrfs.log is generated on demand when downloading the logs so even if you "cleared" the logs that log would still have useful information.

Re: Volume full full with 4TB free
That looks fine, but you could run a balance of your data volume if you want.

Go to System > Volumes, click on the Settings wheel for your volume and choose to run a Balance.
