Good day all
After using Unraid for a few months now we were very happy with 6.5.3 and installed the newer version onto our second 45drives (28 storage, 2 parity and 15 cache) 8TB WD Red Pro+ drives
the first server after figuring out that unraid wanted a specific usb to be used to retain anything after a reboot works like a charm 300mbs+ to shares on it.
However with 6.6.5 on the second machine i get max 20mbs and a failure to use Veeam backup and replication as shown below.
