No volume exists after device restart!! Need urgent help
Hi.
We have ReadyNAS RN31600 as iSCSI target device. We have (had) two LUNs of 8 terabytes each built on X-RAID 5, that are presented to a Windows Server.
This device is under one year old, and it started having issues today. First both LUNs disappeared from the iSCSI client (WS 2008 R2). When we tried rebooting the NAS, it hanged on "Restarting now, see you soon".
We powered it off from the main switch, and after restarting both LUNs seem to have disappeared, and the device is somehow empty??? How do we fix this? Or is it completely normal on Netgear devices to lose suddenly 16 terabytes of data?
The GUI shows "No volume exists" and also "Remove inactive volumes to use disk. Disk# 1,2,3,4,5,6". Meaning all disks.
Firmware is 6.4.0.
And no, we don't have backups, because this device serves as a backup device.
I suggest contacting support (support.netgear.com), as I think that will be faster than starting here.

Please attach logs to the support case (my.netgear.com > log in > "Upload and attach files to open support case").
You can download full logs from NAS GUI > System > Logs > "Download logs"
"Inactive volumes" means that either your btrfs subvolume failed to mount or the RAID for the volume failed. Your logs may clue in on the specific mount error you're having. Without a case number though, we can't look and pinpoint it.
Mr. xxxx xxxx from Netgear support is investigating this. Case number is 26362565.

Looks like you have a btrfs filesystem error:
BTRFS critical (device md127): corrupt leaf, bad key order: block=810713088,root=1, slot=226
I know you mentioned you were working with support. In reality, this error could take several days or weeks to work through.
It looks like you filled up your data volume. It is sitting at 93% which is not advised by NETGEAR. NETGEAR recommends not exceeding 80-85% of total volume capacity (for reasons such as these, as well as performance).
Maybe your ReadyNAS'll let you boot into Volume Read Only mode. Otherwise, to save time, you might want to consider restoring backup of your data. Since OP said this is a backup device, might benefit from just factory defaulting and restarting from scratch (fresh file system).
