ReadyNAS 102 – Blue light blinking, no boot

My ReadyNAS 102 has been working with an issue for a few years. I tried to connect recently and it wouldn't let me. I tried to reboot and it wouldn't so I pulled the power. Now it won't boot up (blue...

Hello FreshIdentity,

Booting the NAS with no disks will really not boot up the NAS completely and will give you blinking power light. The OS/firmware, settings and data are stored to the disks.

Perhaps you want to check if RAIDar will detect your NAS with the disks in. By the way, when inserting the disks back to the NAS, please make sure you insert them back to their respective bays.

When RAIDar detects the NAS, it will show the current firmware, the current status and RAID level.

If the RAID level is XRAID (RAID1), try inserting just one disk to the NAS and see if it will boot up and let you access the files. If you get the same problem, try the other disk.

Welcome to the community!

Regards,

Patience. This is normal. First, the RAID volume is shaped. Then the data is synced to the RAID partitions on the drives. After the resync has happened and the volume switches from DEGRADED to REDUNDANT after the second run through, everything should appear normal.

Thanks for the advice. So I applied patience. The drive resynced and I got a log saying 'Disk in Channel 1 changed state from RESYNC to ONLINE'. Followed by a message this morning saying 'Volume data is degraded'. It appears to be resyncing again so I'll see what transpires...

It has done the resync and I get the same message again: "The resync operation finished on volume data. However, the volume is still degraded"

    Disk 1 is marked as spare: you can see the (S) next to sda3 (disk_info.log shows sda is disk 1) in mdstat.log
    
    Disk 2 is faulty as you can see in e.g. disk_info.log, smart_history.log
    
    So your data is only on disk 2 out of these two disks. You'll need to see if you can backup your data and if that's not possible then it'll be a data recovery situation.
    
    The ST3000DM001 disks are known to have extremely high failure rates.
    
    The NAS disks are much better.
    
    Regardless of which disks you use backups are important.
