If you are a user of the Netgear Readydata series (like the 5200) it’s possible you are ending up with full storage. This is the moment you are unable to delete files from your storage. If you deleted these files it’s still possible you can’t retrieve the new free spaced data.
This article has given some credits to my colleague who figured out what you can do without destroying your folder structure.
First step what needs to be done. You logon to the Readydata with SSH. (be sure you have enabled SSH access).
login with root and you (admin password)
Second step is list the file system
root@NRD01:~# zfs list NAME USED AVAIL REFER MOUNTPOINT LUN01 10.7T 0 45.3K /LUN01 LUN01/._share 1G 1024M 51.3K /LUN01/._share LUN01/._system 10.0G 7.94G 2.06G /LUN01/._system LUN01/.reserved 435G 435G 40.0K /LUN01/.reserved LUN01/BACKUP 10.2T 0 10.2T /LUN01/BACKUP rpool 764M 9.08G 763M /.system
Third step: To delete the full folder on the storage.
zfs destroy LUN01/.reserved
Fourth step: Connect to the share of the storage. Delete some files (in this case a backup). Choose wisely which files you going to remove. Once gone always gone.
Fifth step: Connect back to the storage on SSH. To reconstruct the reserved folder.
root@NRD01:~# zfs create LUN01/.reserved root@NRD01:~# zfs set reservation=435GB LUNN01/.reserved
After these steps, you can use your storage system back as you used before.
