  1. Hi there Thanks for your responses. I've been away form home for a while, so just picking this up now. I can confirm that the setting you mention is already set to "true" so I would anticipate the the behaviour should not be as I'm observing. I can confirm that the Last Modified timestamp for a folder in my pool is that of the first instance of that folder in my disk pool if you enumerate pool parts in the order that disks appear in the pool. For example, if I have a folder called "Test" spread across Disks 1, 2, 3 and 6 by file placement rules with the following last modified timestamps: Disk1: 01/01/2019 05:00 Disk2: 01/01/2019 04:30 Disk3: 01/01/2019 11:00 Disk6: 01/01/2019 06:00 ...then the timestamp reported by Drivepool to Windows is that of the first disk in the pool, i.e 01/01/2019 05:00, not the latest timestamp (11:00) as per the last actual update (caused by a file change within the folder that happens to reside on Disk3). To check this behaviour, I temporarily removed the "Test" folder from Disk1 and the timestamp reported to Windows in the pool drive became 04:30 (for this example). Creating or modifying files that are placed in the Test folder on disks 2, 3 or 6 does not change the folder timestamp in the pool drive. If a file is placed on Disk1, it does. The same behaviour is observed for folders split across disks 3, 4 and 5 - i.e. the timestamp of the folder on disk 3 (the first in the pool to contain that folder) is reported. I believe this is a bug. I think the correct behaviour would be for Drivepool to enumerate ALL instances of a given folder across disks and report the LATEST of those timestamps. This bug breaks any application (including Subsonic as per my use case) that relies on checking folder Last Modified timestamps for its functionality. I've now tested this on Windows 10 as well as on my original Win2012R2 server where I noticed the problem - same behaviour.
  2. Thanks for pointing out the error. Of course, I meant "are not" detected on a forced scan. I have edited the post accordingly. Nope. Subsonic is definitely pointing at the pooled drive, not one of the specific disks within it. Checked, double-checked and triple-checked.
  3. Hi there I've been using Drivepool for a couple of years now and it's been really stable and has generally great. However, I have noticed an issue over the past few months in relation to file watches. Specifically, in relation to Subsonic server that is running on my machine. The scenario is as follows: I have 7 data disks in my pool and most of my music collection is placed only on disk 1, as per a file-placement rule (see attached screenshot). Subsonic (which is a Java application) has code that keeps a watch on the filesystem so that when new music files are added into my music folder, it will automatically detect it, scan the files and add to my music libary. This was working fine, but I noticed that sometimes the files were never detected, even after I forced a scan. Long story short - because disk 1 was getting full, some music files were being placed onto disks 2 and 3 when I copied them to my pool drive. Subsonic a) didn't notice the new files and b) would not recognise the files as new even when I forced a scan. Now, my assumption was that the software used NTFS file watches to detect new files, but that doesn't explain why files are not detected on a forced scan, which I believe from looking at the code is based on file/folder last modified timestamps. If I manually move the music files from disks 2 or 3 on to disk 1, or clear up space so that the file placement rules move the files when I re-balance, then Subsonic detects the files. My hypothesis is that Drivepool isn't properly reporting timestamps or filewatch system events when files are placed on to disks that are not the one(s) chosen in file placement rules. It's taken months to work this out and I spent ages on the Subsonic forums (and talking to its developer) because I assumed that it was a problem with Subsonic. I've now conclusively (and repeatably) shown this is a Drivepool issue. Thanks, Steve. PS: I'm running Windows Server 2012R2 with all the latest updates. I have no AV installed at the moment (I got rid of it while testing this, just in case). I also use Snapraid for parity across my Drivepool disks, not that I expect that makes any difference!
  4. It depends on the controller used in the external drive housing. I've found several times that drives formatted while in the enclosure do not show up as expected in Windows once shucked and connected directly to SATA. My advice is to shuck the drive first, reformat directly in your OS and then use. This would be best whether you're intending to use Drivepool or not.
