[SOLVED] Ready NAS Duo unaccessible after a resync
Hello,
A few days ago, I've received a warning about a resync that have to be done on the NAS
I clicked on it, This warns me about the background task and the fact that the NAS will still be accessible.
36 hours later :
- no frontview access
- no ping response
- no reachable via Raidar
- blue led is still on
- green led are on but not so bright (I sync they might blink to fast for me that leads to a low light intensity)
What should I do ?
- do I have to shut it down ?
- do I have to let it work (besides the fact that I have no clue of what it is currently doing ?
NB : both smart+ where OK before starting the resync process.
Best regards,
Manitooo

- Do you have a backup?
It does sound like one of the disks probably has issues. - basically, it's in RAID 1. so in case of HDD failure, I hope that the NAS will still let me change the drive without any data loss...
For purely backup, in fact not for all data.
But to verify the problème, do I have to shutdown the NAS and reboot it ? - You could try a reboot
- Ok but how do I do.. to be sure to not get the problem worst :
bu pushing the on/off during a few seconds ? - If it has hung then you may need to force power it off
- Well
No reboot allowed via the power on button
So unplug it off then on
Now booting... :
- accessible for ping
- accessible from frontview (system resyncing)
- accessible from raidar (resync at 16 % but seems to be stuck.. ..; File système checking, 100%)
- dlna not accessible
- nfs shares not accessible (thus data not backupable)
Anything I could do to skip the sync in order to access the data ?

Repaired sectors 0 - Disk 1 is bad.
Are you using Flex-RAID RAID-1 or are you using X-RAID?
Do you recall what firmware is on the unit? - OK,
Which parameter(s) lead you to the failure of disk 1 (just to be able to check my other ready NV NAS). I thought about the multizone error rate and ATA error, but it seems that there are still neither CRC error nor Raw read error rate.
And moreover, which paramers should I check continuously to verify my HDD integrity
As far as I remember, the firmware is 4.1.9 and is configure in RAID 1 (the ready nas duo does not propose the X-RAID as far as I remember)
Besides all thoses considerations, I've experienced an awkward behaviour.
The NAS was alive during the past 10 hours and then now seems to be stuck once again ...
What should I Do ? - The ATA errors in this case may be due to using the disks on firmware that doesn't support WD disks that don't support TLER, especially if the ATA error count went up by six at a time and didn't increase recently.
The non-zero current pending sector count shows that the disk is bad.
Your huge Load Cycle Counts indicate that you never ran WDIDLE3 on these disks.
Power down, remove the bad disk and see if it boots
If a sector can't be written, it is reallocated (and that stat goes up). If a sector can't be read, the current pending sector count goes up. It can't be reallocated until there is something to write into the reallocated sector.mdgm wrote: The non-zero current pending sector count shows that the disk is bad.
When assessing disk health you should sum these two counts. 525 is a huge number, normally I replace disks before the count reaches 50.
