Dead Drive

Question: I had a 'data degraded' message on my RN314, and the log said disk 2 was failing. I've replaced that, and it seemed to successfully resync, which was great news!

 

However, Disk 1 status has now changed to FAILED, and is now DEAD.

 

Ouch!

 

If I now replace Disk 1, should it resync again, and all will be OK?!

 

Thanks for any help out there.

Ian

Re: Dead Drive

Can you download the log zip file, and look in mdstat.log? Perhaps copy/paste it into a reply on this post.

Re: Dead Drive

Thx.  Unfortunately mdstat.log isn't showing the RAID volume at all.  But it is showing good status for both the OS partition and the swap partition.

 

Paid Netgear support (my.netgear.com) is the best path, as this is hard to troubleshoot and I don't know of any good guide.  You can try to get per-incident support - but you'll need help from the mods ( @JohnCM_S or @Marc_V ) to get that.  Don't get gearhead support, it doesn't cover what is needed.

Hi IanW,

The pay-per-incident support contract should now also be available for purchase on the myNETGEAR portal (my.netgear.com). You need to be logged in to the account that has the device on it and it will show as an available contract. Feel free to send us a private message in case you do not see that as an available contract when you log in to the portal.
