Two failed disks at same time
Hi all, Last monday this NAS in a client reported at the exact same time the failure of two of the three drives - thus loosing the volume No prior warnings existed and this beeing a backup NAS the ...
I Rebuilt the RAID5
Took the exepcted time. No errors whatsoever
Of course i dont trust this device anymore - it can be the disks but two failures at at the same instant with no smart errors and no errors on the test and on the rebuild points to some glitch on the NAS itself...
As it is 6+ years old I bought a new NAS for main backup and this will be secondary while it works
Thanks all
I would be very surprised if there were not SMART errors in smart_history.log in the logs zip for at least one of the disks. You can easily check this.
I think NTGR would probably require a data recovery contract to look into this, and if this NAS is only holding backups of data stored elsewhere it doesn't sound like that would be worth it.
Thank you for your reply
I am rather new to netgear, where can i find this smart_history.log via ssh ?
As to the configuration, is there a way to install new disks and create the volumes keeping the configuration or is the configuration in the disks themselves ?
Thanks
OK, found it via donwload logs
No errors are reported.
Couldn't find any logs that report an error...
simply at 23h00 last monday: (23h00 is the time a backup starts to this device)

[21/06/15 01:00:02 GMT] warning:volume:LOGMSG_HEALTH_VOLUME_WARN Volume 'RAID5' is 'Degraded'.I made a disk test today via boot menu, is the result somewhere ? Can't find it.
I am concerned this may be some malfunction in the NAS itself. any pointers on how to diagnose this ?
Thanks
You can create a complete log .zip from SSH with rnutil create_system_log -o <filename>.
