At first, I thought it was some strange windows permissions error with Linux and samba, but now I'm not so convinced. I am able to read all the files but I could not change anything on the drive, or change owners. Every time I did it claimed permission denied. Since I could still back up my files I had planned to break the pool and format the drives and see if that would fix the permissions. During that process, I decided to give some of the other drives letters so I could directly see the data in the pooled drives. I was able to modify and make changes to the files leading me to believe there is some problem with drive pool. The physical drives are formatted with REFS which I know is in beta support while the pool is NTFS. I'm guessing this prob h as something to do with it. Do you plan on supporting REFS anytime soon? I'd hate to break this all down and switch over to freenas on a VM for my storage.

https://www.theverge.com/2017/6/5/15739192/microsoft-windows-10-pro-for-workstations-advanced-pcs-features In a leaked slide, Microsoft describes the edition as “Windows 10 Pro for Workstation†with four main capabilities: Workstation mode: Microsoft plans to optimize the OS by identifying “typical compute and graphics intensive workloads†to provide peak performance and reliability when Workstation mode is enabled. Resilient file system: Microsoft’s file system successor to NTFS, dubbed ReFS, is enabled in this new version, with support for fault-tolerance, optimized for large data volumes, and auto-correcting. Faster file handling: As workstation machines are typically used for large data volumes across networks, Microsoft is including the SMBDirect protocol for file sharing and high throughput, low latency, and low CPU utilization when accessing network shares. Expanded hardware support: Microsoft is also planning to allow Windows 10 Pro for Workstation on machines with up to 4 CPUs and a memory limit of 6TB. Windows 10 Pro currently only supports 2 CPUs.

Hello, Can I mix NTFS and ReFS drives in my pool ? I am using Drivepool version 2.2 beta.

I've read Drashna's post here: http://community.covecube.com/index.php?/topic/2596-drivepool-and-refs/&do=findComment&comment=17810 However I have a few questions about ReFS support, and DrivePool behavior in general: 1) If Integrity Streams are enabled on a DrivePooled ReFS partition and corruption occurs, doesn't the kernel emit an error when checksums don't match? 2) As I understand it, DrivePool automatically chooses the least busy disk to support read striping. Suppose an error occurs reading a file. Regardless of the underlying filesystem, would DrivePool automatically switch to another disk to attempt to read the same file? 3) Does DrivePool attempt to rewrite a good copy of a file that is corrupt? Thanks!

With alternate streams now available on ReFS in Windows 2012 R2 and 8.1 will Drivepool support ReFS volumes in the future? NTFS has been a solid platform for many years, but MS has, with the introduction of ReFS in 2012 provided a real alternative with many new benefits, so I think a lot of us are considering a move to ReFS in the foreseable future especially for the frequent write-once-read-seldom scenarios that most of us have with media libraries and file servers. This is actually not so very different from the ZFS/BTRFS vs. EXT3/EXT4 discussions the linux community has. I am wondering what thoughts you guys have about ReFS and where do you think DrivePool/Scanner is headed with regards to ReFS? regards F. Godskesen "Microsoft Windows 8.1 adds support for ReFS volumes and, compared with Microsoft Windows Server 2012, both Windows Server 2012 R2 and Windows 8.1 add additional features when using ReFS, including alternate data streams and automatic correction of corruption when integrity streams are used on parity spaces." http://en.wikipedia.org/wiki/ReFS http://www.petri.co.il/4-reasons-refs-is-better-than-ntfs.htm http://forum.covecube.com/discussion/1031/refs-support/p1
