RN104: Disk failed, replaced, resync, data still degraded, NAS reboot = repeated resync problem

Hello everyone Michał from Poland here,

 

I have a RN104 with 2x 4TB WD drives (initially 2x WD Green [Desktop i know]).

Recently one of the drives has been failing, so i replaced it with a 4TB WD Red, everything was going fine, few hours of resync and done.

 

Now i have 2 problems:

  1. Both disk show a green light, but the data is still degraded. Any ideas what should i do to bring it back to normal?
  2. After resync has completed - i have restarted the NAS (3 times now) - after the reboot - data resync starts over again (it takes a few hours).

I have searched the forums and google for an answer but no luck... maybe somebody can help me out with my problems. Below are the recent logs, and a screnshot:

 

15 Jan 2019 01:00:18 Volume: Volume data is Degraded.
15 Jan 2019 00:44:01 Volume: The resync operation finished on volume data. However, the volume is still degraded.
15 Jan 2019 00:43:51 Disk: Disk in channel 1 (Internal) changed state from RESYNC to ONLINE.
14 Jan 2019 18:14:43 System: ReadyNASOS background service started.
14 Jan 2019 18:14:32 Volume: Resyncing started for Volume data.
14 Jan 2019 18:14:32 Volume: Volume data is Degraded.
14 Jan 2019 18:11:31 System: The system is rebooting.

Re: RN104: Disk failed, replaced, resync, data still degraded, NAS reboot = repeated resync problem

Can you check the SMART stats for both disks?  Perhaps also copy/paste mdstat.log here (you can use the "insert code" tool for that).

 

Also, what firmware are you running?
