FreeNAS VM – EFI Booting

Leave a comment

Recently I updated my FreeNAS installation to the latest version. This now supports VMs. I installed a Centos VM to run a CrashPlan backup service. However, I noticed that the VM always went back to the EFI boot menus when it rebooted – not much use…

I found the following solution –

Using the original install CD I used the ‘Rescue’ option to boot my installed version. I then used chroot /mnt/sysimage to get to the installed files.

You then need to make some changes to the EFI boot file locations

After this everything should boot fine – however, make sure you update the CDROM device to remove the .iso file – if not, the VM will constantly boot into the setup CD! If you have issues with deleting the entry to the .iso image, just create a zero length file, call it ’empty.iso’ and point the device to that.

FreeNAS – Authentication Issues with Windows 10

Leave a comment

After upgrading my FreeNAS server to the latest version the other evening I started to experience some issues with my Windows 10 workstation being able to authenticate with and then access the files on the FreeNAS Server.

After some checking around it became apparent that there was an issue with the user authentications. The following appeared to fix the issue –

Change the logging level on the FreeNAS server for the SMB service so that the issue was visible – Services > SMB > Log Level ‘Normal’

View the log file and see the authentication issues – tail -f /var/log/samba4/log.smbd

Verify that your password in Windows and on the FreeNAS server match.

Delete any shares on the Windows client that may have cached credentials – net use * /d

You may also want to look at setting ‘ntlm auth = yes’ in the ‘Auxiliary parameters:’ section of the SMB Services Configuration
