Thanks
It has booted at least looks normal, should I be able to access the volume when a disk has failed and dead?
Just got to wait on delivery for drive tomorrow and plug in and hope for the best.

If you are using XRAID or a RAID mode with redundancy (RAID-1 or RAID-5), then yes.
- mrl2000Nov 18, 2021AspirantThat's interesting as it is a raid mode, can't remember which one, thought it was 2 and 2, but actually all disks are 1tb but total size is 2.9 tb with 2.7tb available.

ReadyNAS uses TiB units (1024*1024*1024*1024 = 1 TiB), and that gives 3.85 TiB for the volume size.
