X-RAID 2 Operation and Downsizing
I've tested answers in other posts on my NAS and found some of them to be incorrect, so please cite when you can to support your response. Questions: (1) If I lose a disk in a RAID-5 and don't have an equal capacity replacement on hand, can I use a smaller disk to fill in the dead disk's place until the new disk arrives? (This would downgrade the RAID volume to a lower capacity for the interim). (2) Since X-RAID 2 works by creating layers, does the answer to (1) change if my array was originally created on smaller disks, and my temporary disk is the size of the original disks that my volume used to be made of? Or do those layers disappear each time the volume expands? (3) I currently have disks of varying sizes in my array and the ReadyNAS is utilizing 100% of their capacity. If it can do this as they're added to the array, regardless of what order their added, why can't it downsize if there is free space to do so? Please explain this in detail, rather than saying that XRAID is meant to be expandable only (a common answer I've found to similar questions). (4) If anyone knows where there is a full technical specification breakdown for X-RAID 2, please post it. It would be helpful to have an X-RAID bible around for future reference. Thanks for your time! NOTE: For others who are curious the best discussion I've found on X-RAID is at the link below, but it doesn't directly address the questions posted above. https://community.netgear.com/t5/ReadyNAS-in-Business/Expansion-with-X-Raid2-resulting-sizes-and-different-reported/m-p/969415#U969415.Solved5.9KViews0likes10Comments
