I have having problems replacing a drive in my ReadyNas 316. I have added/replaced drives many times and this is the 1st time I have run into this issue. In the past the NAS accepted the drive and resynced all the data.
I found another post that suggested formatting the drive with the button on the right, but that does not appear to have done anything. All the data is still accessible, but the NAS is in degraded state.
I am running the latest stable version 6.10.10
The logs do not show anything, but me removing the old drive and putting in the new drive
Re: Readynas 316 disk state unknown after replacement
I'd be looking for errors in various logs (system, kernel, systemd-journal) around the time you inserted the new disk. Also I'd check mdstat to see if the new disk was synced to the OS partition (md0) or not. Probably look in disk_info.log also.
If you like, I could take a look. You'd need to PM me a download link to the logs.
But I think the first step would be to test the disk. That can be done with WD's utility in a Windows PC, but also you could run the long test with smartctl from the linux command line. Do you have ssh enabled (and have experience with the linux command line)?
Re: Readynas 316 disk state unknown after replacement
Found this in the rn-expand.log file
Looks like it might be a bad drive? I will take it out and try it in a PC.
