Drive replacement for Readynas RN10400
Where in the netgear provided handbooks does it provide instructions for 2 of 4 failing drives. For example, does new replacement drive need to be formatted. Can 2 drives be replaced at same time. Will I lose data from remaining 2 drives during this process. Does server need to be in boot mode, etc. Ordinarily, disks can be of different sizes - is this true for replacement disks as well?
Failed drive replaced in Pro Business, can't tell what's up.
I've had my Pro Business for years now. I've moved from 6x500G to 6x1T to 6x2T over the years, and have always used Seagate Constellation ES.2 drives. I have a drive failure about once every 18 months or so. Each time it happens I recall not seeing enough info from the NAS to tell where the NAS is in the rebuild process, so I'm used to waiting days for the alarms to clear, but I had a recent failure and am getting nervous. Drive had been getting progressively worse with increasing SMART errors. I always keep a spare handy. I am running XRAID-2. Drive finally failed, so I replaced it. The log shows the following messages after the failure and then after the replacement with the new drive: I have waited over 10 days to see the alarms clear and the drive to go "normal" but no joy. Drive is still showing "dead" in the volume and health displays, and front panel shows "Vol C degraded". I don't want to reboot if it's busy, causing it to have to start over. How long should this take, and how can I see updates on the rebuild status? Thanks, H.
