NAS4Free Upgrade to 9.3.0.2.1349

I was running the previous version for more than a year and was happy about it.  But the itch for change was there.  The release page warns about the need to reinstall things from scratch which I did.

• Saved current configuration
• Used Win32 Disk Imager to burn live USB image to a small 1GB USB flash disk.  
• I booted from the flash disk and chose a very first option to install the embedded version to a compact flash card sitting in a parallel IDE connector.
• Set IP to a static 192.168.1.10
• Booted the NAS and restored configuration using Web GUI.
• NAS rebooted.

Here are some bumps I have so far:

• While moving the NAS box (I used the opportunity to open it up and dust things off) I reconnected UPS USB cord to a different port.  Now UPS is not recognized - I have
       ERROR: Data stale!
  That is NOT helpful.  Replugging the cord and restarting the UPS service addressed this.
• I noticed I am actually overclocking the CPU and instead of 1.8GHz run it at 2.6GHz!  Yet the Web GUI reports CPU as running at 1.8GHz.  No biggie, just something to keep in mind.
   
• Most troublesome!  I now have a warning:
  

  
    pool: tank
   state: ONLINE
  status: One or more devices are configured to use a non-native block size.
   Expect reduced performance.
  action: Replace affected devices with devices that support the
   configured block size, or migrate data to a properly configured
   pool.
  config:
  
   NAME        STATE     READ WRITE CKSUM
   tank        ONLINE       0     0     0
     mirror-0  ONLINE       0     0     0
       da3     ONLINE       0     0     0  block size: 512B configured, 4096B native
       da0     ONLINE       0     0     0  block size: 512B configured, 4096B native
  

  
  I am confident this was not there before the upgrade. These are Seagate NAS drives: ST4000VN000-1H4168.

Something to consider for future use after I upgrade all clients to Windows 10 -  in Services|CIFS/SMB|Settings change Max Protocol to SMB3.  Here is a relevant read.
