I am confused by the usable capacity i am getting from a PS6510 with 48 x 2TB Disks. So total this Array has 96TB RAW but after the initial configuration I manage to connect to the array and apply a RAID 6 configuration. The GUI notes that the usable capacity should be 69.08TB with 47 disk in use and one spare. After applying the config the arrays usable capacity immediately jumps up to 26.64TB and has stayed there for the past 5 hours. There are no errors on the array but the RAID Status is "verifying" and progress is at 6%.
I have looked all over and cannot find any documentation on this behavior, and it is pretty concerning for a storage device to give you only 28% usable capacity even with any RAID configuration.
Is this normal? Does it just need to complete verification of the RAID before it will give access to the whole 69.08TB capacity? And if so why would it give access to 26.64TB before verification has completed?
UPDATE: after completing the verification the PS6510 remained at 26TB of usable storage. I then safely rebooted the device and it defaulted the other Type 10 controller. When viewing the disks on this controller it had more then half marked as foreign disks instead of online. From there i managed to readd those disks and the available space jumped from 26 to about 53TB still 16TB shy of the orginal configuration estimate of 69TB. at this point I have absolutely no idea why it is creating a 53TB storage pool instead of a 69TB storage pool.....
