I just purchased a WD My Cloud EX4 8TB.
It is running in RAID 5 and I have disabled as many of the shares & services as I could.
I’ve created an iSCSI volume of the largest size I could- 5800GB IIRC. This is my intended use for the NAS.
The dashboard shows only 81.0 GB free. I do not plan on using any of this remaining 81 gb.
On the dashboard, I have an alert Code 1001 “Volume Usage is Above 95”.
“Your volume 1 usage is close to full capacity. You may begin to experience performance issues. Ensure that your files are backed up, then move files off of your drive to create free space.”
Does the EX4’s OS need unused drive space as temp buffer?
Will I run into performance issue? (bearing in mind that iSCSI is the only service I am using)
I’d like to know sooner rather than later, whether I should format the system again and create a < 95% sized iSCSI volume.
