what is the conflict between smr and raid?
Look here: https://www.servethehome.com/wd-red-smr-vs-cmr-tested-avoid-red-smr/2/
Note particularly the section that says:
Unfortunately, while the SMR WD Red performed respectably in the previous benchmarks, the RAIDZ resilver test proved to be another matter entirely. While all three CMR drives comfortably completed the resilver in under 17 hours, the SMR drive took nearly 230 hours to perform an identical task.
The RAIDZ resilver operation is similar to what your NAS does with a resync and vertical expansion.

so sounds like if i reoplace the 1st drive the wd smar drive i might be able to use full capacity
I think the next step is to re-download the log zip file, and see what the current status of the mdstat.log is. I understand that the web ui might show the resync as completed, but I think it makes sense to look more closely in the logs.

2915738496 blocks super 1.2 level 5, 64k chunk, algorithm 2 [4/4] [UUUU]The resync has completed. Your array has 2 RAID groups (shown above)..
The problem is that md126 is missing one of the disks (sdc).
Can you also look in disk_info.log at sdc? It'd be useful to know what disk it is (and double-check the size).
this s the disc )=-info.log

if i deleted the volume and created a new one and restored data from a backup would i be sure to get the full capacity expected? or am i looking for a needle in a haystack trying to work this out?
The space you are missing is on disk 3 (sdc).
Perhaps remove disk 3, and then reformat it (or unformat it) in a Windows PC. Then reinsert it, and see if after resync you get the full space. If you reformat it in Windows then you'll need to reformat it again in the NAS.
Definitely make sure your backup is up to date first though.
i only have a msc so will only be able to format it using disk utility any particular format type i.e fat32 macos extended etc? is it possible to format that individual drive in the nas itself?
Petroc wrote:

What is an msc?
The format used in the PC actually doesn't matter - the point is really to remove the NAS formatting, and then have the NAS reformat it again. Unformatting (for instance with the windows disk manager), or zeroing the disk (using a number of utilities) will work just as well.
You'll need to remove the disk from the NAS though, as it won't let you remove the disk from the array.
Typically, just removing any partitioning with a PC is sufficient, especially removing any system reserved partition since the NAS can't handle them (can't even delete them).
will that be enouggh t make te nas think its a completely new drive?
- So having formatted the drive I have judt out it back in and it’s doing nothing with it I hesrd it soon up but it hasn’t even recognised it as a new disk
Maybe try powering down the NAS, and removing the existing disks (labeling by slot).
Then try powering up with the disk in slot 1 (other slots empty), and see if it is recognized. You'll need to do a factory default procedure from the boot menu.
- Do you mean the disk just inserted in slot one feafault reset and then Reload with the disks in correct position?
Petroc wrote:

So start with slot 1, and do a factory default - that should install the OS on the disk, and create a jbod volume. If it works, then power down, move the disk to slot 2 and reboot. Continue until you've tested all 4 slots.
Assuming the disk is detected and will boot from any slot, then the next step is to try again. You'd remove the disk, and power up with all the other disks in their correct places. The system should boot, though the RAID system might say that it's degraded.
Then connect the problem disk to your mac and format it again. Hot insert it into the NAS (while it is running). The disk should appear on the volume page. If you select it, you should be able to format it. If XRAID is on, then it should be immediately added back into the array.
i've taken the nuclear option of filling the unit with all drives i have available and doing a factory default now restoring data from backup the volume ca[acity is 8.17 tb with 1x4 3x3 drives better than i had for sure and at least i'm now usingall my disks that are otherwise unused
