log msg "Detected increasing spin retry count"

[Ludovic]

Hi all,

I have a NAS (Netgear ReadyNAS Ultra 2) that runs two Hitachi drives in a RAID 1 config.

Recently, I saw a message showing up in the logs about "increasing spin retry count" on a disk, and advising that I replace that disk.

So I grepped through my logs to see whether this message showed up more, and found the following occurences:

Code:

status-old.log:2!!Wed Oct 21 09:08:06 CEST 2015!!root!!Detected increasing spin retry count[327682] on disk 2 [Hitachi HDS5C3020ALA632, ML0220F30ZWHHD]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
status-old.log:2!!Wed Oct 21 09:09:30 CEST 2015!!root!!Detected increasing spin retry count[327681] on disk 1 [Hitachi HDS5C3020ALA632, ML0220F30ZBR0D]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
status-old.log:2!!Fri Oct 23 14:47:55 CEST 2015!!root!!Detected increasing spin retry count[131072] on disk 2 [Hitachi HDS5C3020ALA632, ML0220F30ZWHHD]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
status-old.log:2!!Fri Oct 23 16:47:03 CEST 2015!!root!!Detected increasing spin retry count[65536] on disk 1 [Hitachi HDS5C3020ALA632, ML0220F30ZBR0D]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.

So the same message showed up on two occasions, and at each occurrence the message was given for both drives. This looks like it can't be a coincidence to me?

So I'm assuming something happened with the NAS or the monitoring software at these moments, and that the drives are actually fine. But as I'm not an expert on HDDs, I was hoping someone here could share their thoughts on this...

Also, I tried to run a SMART check, but to be honest I still haven't figured out quite well how those work. Are there smart checks I can do (e.g. with smartctl) that gives me an answer (e.g. 60% chance of failure in the next 2 months), instead of just a bunch of numbers that I need to interpret?

Thanks a lot!

Anyone a clue about this? Or is this the wrong forum to post this to?

i think this is the right forum.
before doing anything, backup your data.

well, how long you are using this NAS ?

a detail s.m.a.r.t report would be required to understand more, Hitachi drives are more reliable as per many studies but yet they can fail. Spin Retry Count: is the spin start attempts to reach the fully operational speed, increase in this attribute value is a sign of mechanical problem with hard disk.

attach s.m.a.r.t report here so someone can help you understand the problem if there are any.

good luck.

since you think your HDD(s) are fine

So I'm assuming something happened with the NAS or the monitoring software at these moments, and that the drives are actually fine.

and since it's DR forum i think you have to try Netgear ReadyNAS forums

but if you want some help with your HDD

I tried to run a SMART check, but to be honest I still haven't figured out quite well how those work.

upload the smart here or you can read about smart here
