I was wondering if you oculd help with my ReadyNAS NV+ RND4000
Basically, it's the kernel panic issue, however, when I remove one specific drive, it does boot up, and I can access the web admin, but just not the data.
It says it is healthy and redundent, so do I just need to buy a new 2TB drive and it will sort itself out?
Also, is the order of the drives important? According to xraid_config, the numbers seem off, but when I swapped them around I got kernel panic, details below:

This part seems a bit odd. You ought to be able to access the data. Have you tried downloading the log zip file?
Also - do you need to off-load the data? Or do you have backups of whatever you need?
Have you tried testing the problem drive in a Windows PC with WDC's dashboard software?
See attached screenshot, there is no file in the list of log exports called "mdstat.log"
The error message I get in the web is :
The paths for the shares listed below could not be found. Typically, this occurs when the ReadyNAS is unable to access the data volume. media webroot addons-config
See attached screenshot, there is no file in the list of log exports called "mdstat.log"
My bad, the NV+ uses lvm, not mdadm for RAID.
Look in volume.log
Also, disk_smart.log will have information on what disks the NAS is seeing, and of course some health info (reallocated sectors, pending sectors, etc).
No shares in windows file explorer. I see the share exists in the web admin interface.
Here is volume.log - not sure really what this is telling me: I have a drive in 1, 3 and 4 at present:

Note it is only seeing SMART information on two drives - not sure what slots they are in, you'd need to power down and check the serial numbers to see.
Also, WD-WCAZA6665747 isn't healthy - some reallocated sectors, but the current pending count is almost 500.
The missing drive says this:

Smartctl: Device Read Identity Failed: empty IDENTIFY data
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
one disk which is on the edge of failure (~500 bad sectors)
one disk which won't respond to smart requests
one disk with unknown status (system won't boot with it inserted)
You need 3 working disks to retrieve all data - it's not clear to me whether you have that or not.
I do suggest testing the two last disks in my list with WDC's dashboard software. My guess is that the one that isn't responding to SMART will fail, but it would be useful to confirm. Odds of recovering data would be much higher is the one you removed turns out to be ok.
Okay, so I have taken out the disk that was at the edge of failure, inserted the removed disk, and the system is now loading, it is doing a FS check, and is currently at 94%, so hopefully with these 3 disks I may be able to retrieve my data?
So odd, because it was working just 2 days ago.
Once in, and assuming it does not do a kernel panic, I'll export all logs and maybe we can see what is the status of the other disk.

Hopefully yes.
If you do see the data, you should immediately off-load it. WCAZA6665747 is definitely on borrowed time.
Yep, I have my data, moving it now - hope it doesn't fail.
Does this mean that WD-WCAZA6666340 is dead because of no SMART data?
...and THANK YOU SO MUCH
I actually ordered an extra drive to resolve this, hoping that putting it in would rebuild the array, I guess I don't need that now? Or should I add it to help with copying off the data?
Also, it says I am redundant, but I don't see how I can be with 3 disks in. The system won't work with just 2 will it?

Something definitely went wrong when the system tried to query the SMART data.
After you off-load the data, I recommend testing all the drives in a Windows PC with WD's dashboard (running the long generic test). You might need to purchase a usb adapter/dock (which are inexpensive).
