[SMB Windows transfers fail with "There is not enough space on the disk."]

Transfers from multiple windows clients repeatedly fail with a "There is not enough space on the disk." 

windows side:

1. Failures from windows explorer / Xcopy no difference
2. "Retry" can be pressed multiple times and will restart, then fail
3. No other access / permission issues 
4. 10GBE NIC's on clients
5. pinging no issue  Reply from 10.1.1.93: bytes=32 time<1ms TTL=64

Unraid side:

1. No log entries generated (is there a way to increase logging level?)
2. Target share (/data) has 70 TB free
3. Errors seen with SMB settings "Enhanced Mac ON/Off"  (currently OFF)
4. Errors seen with SMB settings "SMB MultiChannel ON/Off"  (currently ON)
5. 10 GBE on Unraid eth

 

I've been testing (fiddling) with the share's use of cache pool; - was 'yes' but when I change to 'no' - it seems to be not be failing, but really need re-enable for performance.   FWIW, share (data) cache (hdd) is 3*14 TB btrfs raid0, as trying to transfer 100 TB into array.

 

 

 

There is not enough space on the disk.
