Description
Error can occur for a Linux-based NAS running the ext4 or XFS file systems Tested with: QNAP-212 Alienware Droboshare
On Windows Server 2012 (and Windows Server 2008, intermittently).
Error message can occur when performing a system protection backup job from Windows Server 2012 to a NAS (Linux-based file system - ext4 or XFS). The problem can be caused by Samba (SMB/SMB2) timeouts when writing large files from Windows NTFS file system to the Linux-based sparse file system.
Resolution
Verify and update the Samba (SMB/SMB2) Configuration
1. Login to the Linux-based NAS using a Telnet client like Putty
2. Locate the smb.conf file (typically, /etc/config/ or /etc/samba/)
3. Open the smb.conf file and review the contents
4.The strict allocate = yes boolean would be absent or set to no in the default smb.conf file
5. Edit the smb.conf file
6. Add the following configuration to the top of the file: strict allocate = yes
7.Save the smb.conf file and exit
To apply the new Samba configuration the smbd service or the Linux-based NAS must be restarted.
To restart the service without rebooting the system, login to the NAS and execute the following command:/etc/init.d/services restart
Alternately, restart the NAS according to the manufactures instructions.
You should also check that the NAS drivers and firmware are up to date. The drivers and firmware will be available from your NAS vendor.
