  • Hi Ron, yes this would work and no it doesn't matter to DrivePool. So long as WHS can still see it as a local drive, the pool is happy.
  • Hi alexB, the ultra-short version is DrivePool is an abstraction layer (software) and the Backup Wizard only works with physical drives (hardware). You can still tell the Wizard to backup your E,F,G drives (or parts thereof) but: * the Wizard has a …
  • It all depends how any given backup solution stores its snapshots. If it uses multiple (x>2) files for any one snapshot, it's going to risk the same problem. Acronis, for example, is "safe" as it stores images as a single file (depending on how y…
  • Hi Toby, I would suggest contacting Alex via http://stablebit.com/contact with this problem. In the meantime, I'd be curious to see whether you have any problems when you use TeraCopy instead of Explorer, and just how much data you're trying to shif…
  • Hmm. I don't know if DrivePool makes use of NTFS alternate streams (AS) at the file level, but I'd be curious to see what kind of performance hit you'd get from calculating the MD5 or SHA1 hash when writing the file in the first place and adding it …

  • Hi Jay95, try Control Panel, Uninstall a Program, and look for Stablebit Scanner. (you'll have to Remote Desktop into WHS of course)
  • I suspect you have two separate issues? (1) Monitoring folders for changes: customise DrivePool's config file to enable CoveFs_SynchronizeDirectoryTimes as explained in http://wiki.covecube.com/StableBit_DrivePool_Advanced_Settings (2) Weird non-exi…
  • Hmm. Seems like you have an opportunity to do some tests as to if/how drivepool reacts to mis-matching duplicates. More seriously, the safe action would be to copy the known good physical copy to a different non-pooled disk before doing anything el…

  • Hi casiupao.  Short answer: ONLY if you have duplication enabled for EVERYTHING in your pool drive. And even then, afterwards DrivePool will need to re-duplicate anything that was on at the time, because when you reinstall WHS it will format the sy…
  • * If you wish to recover a deleted or past version of a file from the DrivePool, it may be recoverable if its physical location was on a Shadow Copy-enabled drive and Shadow Copy had taken a snapshot of that file. This will depend on the drive's Sha…
  • As I understand it, Shadow Copy (SC) interacts with DrivePool (DP) as follows: * SC's snapshots take up space on an SC-enabled drive. This is, therefore, space that DP won't have available. * SC takes snapshots, by default, at 7am and 12pm Monday th…
  • In a nutshell, DrivePool provides file-level redundancy (plus drive aggregation) while Shadow Copy provides block-level snapshots. For more info on Shadow Copy, see https://en.wikipedia.org/wiki/Shadow_Copy
  • You can still use CHKDSK on individual drives that are in the pool.
  • If you attempt to run CHKDSK on the DrivePool drive it will refuse to check the volume (unsupported file system), even if you have configured the CoveFs_ReportAsNtfs option to True.
  • DrivePool 1.0 is the "finished product". There should be only minor patches from now on, same as any other "stable release" version of software. Alex has stated he has further plans for DrivePool, but hasn't (yet) gone into specific detail, and we h…
  • Hmm. Have you tried forcing a Drivepool consistency check? If that doesn't help, I would suggest reporting it as a potential bug via the stablebit.com contact form.
  • Hi, do you get the same result if you try to move a shared folder that isn't in the pool? You can also use the Resource Monitor that comes with WHS2011 (Start button, type Resource Monitor) to see what files are open and by what processes.
  • To disable server backups and free the backup drive(s) for the pool: From the server Desktop, open Dashboard, click Computers and Backup, click your server's name, click Customize Backup for the server, click Next, click Disable Server Backup, click…
  • That fixed it for me. Thankyou, Alex.
  • There does seem to be a problem with the top menu of the site. I'll message Alex. Edit: contact form's bugged too. Will go the long(?) way.
  • The wiki states that a fresh copy of the default config is written "on upgrade" (presumably it may include any new settings that have been added by the upgrade). If you wished to check whether your config is being applied, you could try changing a s…
  • The former. SMART doesn't go looking for errors, it only reports them when they are found (e.g. when you go to boot windows or open a document). Scanner goes looking and brings SMART along for the ride, similar to what the test programs provided by …
  • You could add D to the pool now - if you're using duplication for everything in the pool, you don't have to worry about losing pooled files even if you have to reformat WHS.
  • Hi Scott, thanks for the technet link! I've asked Alex about the DELETE folders.
  • I think from the viewpoint of the end-user, exactly *how* DrivePool achieves the ability to direct certain files to certain disks and whether the developer calls this ability "pools" or "groups" is irrelevant so long as the UI remains elegant and th…
  • Ah. There's no problem with having a drive both host shared folders directly and be in the pool (I'm using that facility myself). I suspect the problem is an incompatibility between DrivePool and your machine's RAID-5 implementation.
  • Try the following steps: uninstall DrivePool, reboot, delete C:\ProgramData\StableBitDrivePool and reinstall DrivePool. What is it doing after this?
  • Hi Scott, * If you go the cloning route, keep the original disk handy until WHS successfully reboots in its new two-disk configuration - I don't see why it shouldn't, but just in case.... * While many (including me) prefer not to have the Client Com…
  • Are the drives also disappearing in Disk Management? If so, that might indicate a driver or hardware problem.
  • Hi dvdluvver, sectors marked as bad by the file system (i.e. run a chkdsk /v on the drive and it should mention them) do NOT get written to by Windows (or thus, DP). The risk you are taking is that those might not be the only sectors that are (going…
