Lost all disks after firmware 6.9.4 upgrade
Shortly after upgrading to firmware 6.9.4 I lost the data volume and all four disks are marked red. There's an alarm saying "Remove inactive volumes to use the disk. Disk #1,2,3,4."
I have a ba...
I have a feeling it may be related to 6.9.4, as I upgraded the other day and I've had the same issue as you.

Generally speaking, there are quite a few posts reporting it after a firmware update (not necessarily 6.9.4). I'm not convinced the update itself is the cause - it's also quite possible that some checking that is done post-update (or even during the reboot) is uncovering a latent issue that was actually there before. Most people only reboot their NAS after an update.
It would be good if Netgear provided more information on the causes, and looked into prevention or repair of the more common ones. This issue happens much too often.
toresetre or UnknownAXHF，
Could do you please enable secure diagnostic on NAS admin GUI and PM me 5 digit number?
Let me remote access to check what problem happen?
RAIDar Secure diagnostic
https://kb.netgear.com/27391/ReadyNAS-RAIDar-6-0
or enable secure diagnostic in NAS admin GUI =>System=>Settings=>SupportNot to flame anyone/anything or accuse anyone/netgear:
Don't you agree that this have been happening more often after the introduction of 6.9.3?
There have been lots of new firmwares and the inactive disc/s juste showed up?I'm one of thoose that got affected by it and never really found the root cause.
I reboot now and then, have schedules for discmanagement running and never had any errors there. Or warnings.
Anyway, i think Netgear have good products, semi decent support OF COURSE WITH exceptions to the better...
keep up the good work this community does!!

I remote access your NAS and find filesystem is failed, so data volume can't be mounted after NAS reboot.
Could you please create a support case?
