Thanks for the explanations. Glad to know all is good.

So, before I rebuild my 26TB system wanted to toss my issue out there and see if there is something I can do. Basically, what I have is VSS issues on my drive F (pooled) drive and IO issues: The IO operation at logical block address 0x0 for Disk 11 (PDO name: \Device\00000054) was retried. Disk 11 is my F, pooled drive. I try to chkdsk on it and I get the error, "The type of the file system is RAW"; however in Disk Manager it shows as NTFS and outside of VSS not working on the pool, btw it used it, there is no other issues with accessing data. I thought in the past I could run chkdsk on the pool, but truthfully cannot remember. Event viewer while trying chkdsk: Chkdsk was executed in scan mode on a volume snapshot. Checking file system on F: The shadow copy provider had an error. Check the System and Application event logs for more information. A snapshot error occured while scanning this drive. You can try again, but if this problem persists, run an offline scan and fix. Cannot run offline scan and fix as chkdsk thinks its a RAW file. Outside of rebuilding my pool and reformatting, any ideas? BTW, I have run chkdsk on each drive in the pool and no issues found on any drives.

Yeah, if they come out and give a good upgrade price from Pro to Workstation of say $50 - I'd be ok with that. Right now though I am seriously deciding if I want to switch my pool back to NTFS from ReFS until this is all sorted out and support is more defined. Would be painful but I think we are still a year or more away from serious ReFS support including full support within DrivePool and other applications.

Yes, stopping the application allows for duplication to proceed with no errors. But the problem is I have duplication turned off on the folder, I have a file placement rule so that only drive 7 gets CP data yet I can see it being written to on my SSD which is being used by the SSD Optimizer plug-in. Why is that? I believe that is the underlying issue, the plug-in is not following the rule.

I am getting a Duplication warning about files in use. However, I thought I had things setup on the folder in question to prevent duplication of the folder or any management of it. I use CrashPlan and it seems while data is being written into the CrashPlan directory I get "File in Use" errors. I have duplication off for this folder, I have it set in File Placement for Crash Plan to only be on one drive, yet I get the error. I also get the error on a System Volume Information folder which I would have thought DrivePool would ignore. I also get a warning about data couldn't be moved because a suitable destination could not be found. However, we are talking about the drive I have Crash Plan using, it has like 4TB available on it. What am I missing here? I don't want DrivePool to touch or manage the Crash Plan directory and I want data written directly to it. BTW, I am using the SSD Optimizer plug-in but it seems looking at the disk performance area I only see Crash Plan going to the correct drive.

Just a reminder that in Fall Creator builds (Insider) that ReFS support is removed probably due to OneDrive not supporting it. FSUTIL does not have the option any longer. As of build 16257 the Format option via PowerShell looks to still be available, but formatting via File Explorer has been removed. I suspect all support to create new ReFS drives will be removed in Home and Pro versions of Windows 10.

My .02 is that they are removing ReFS support for Home and Pro builds of Windows due to issues with OneDrive only working on NTFS drives. As of build 16257 support still missing and I don't believe it will be back until ReFS has full support of NTFS features.

Cannot install SSD Optimizer plug-in on build v2.2.0.773, says DrivePool 2.x needs to be installed. Trying to install v1.0.4.11 of the plug-in.

Have build 757 on my desktop and 50% of the time when I go into Pool Options >> File Protection >> Folder Duplication I get "Unable to enumerate folder, Access is denied" errors. A reboot usually removes it. I have also had many issues with dealing with Security at the folder level, with out of order, etc. I have reset the permissions on the whole pool and it seems the security issues have stopped but not the "enumerate" issue trying to set the folder duplication. Also seem to get a lot of yellow under Pool Organization about Duplication inconsistent even though pool was green and nothing much has happened. I do have the SSD Optimizer add-on and it is the only Balancer selected except for Scanner - default settings. And unless I'm really blind in this build I don't see anywhere to turn on logging, clicking on the cog doesn't have the option.
