Should have mentioned - did what you said in Q2150495 and it worked!! Thanks

Thanks Christopher - inthe instructions you say "run lodctr /e:PerfDisk". is the e: referring to the pool volume or what?

I'm running several Pools using Beta Version 2.3.1.1410 BETA in Windows 11 21H2 (although same behavior in 22H2). This always used to show activity, not sure when it stopped. If it helps, all the disks are operating with drive letter removed. Any clues?? Anything useful I can provide?

I have a pool (call it IANSPOOL) which has the following file system structure within it .... IANSPOOL --->Music --->ITunes ----ITunes Music I now create a symlink at IANSPOOL\Music\Music which points to IANSPOOL\Music\ITunes\ITunes Music I used "mklink /d " to create the symlink I checked that this worked, and sure enough I can display IANSPOOL\Music\Music in File Explorer and see all of the files under IANSPOOL\Music\ITunes\ITunes Music. IANSPOOL is shared on my network as \\ROOTMACHINE\IANSPOOL, and I checked that the symlink worked through the network. No problem. Later that day I noticed that one of my applications that makes my music library available as a media stream only had a fraction of the library available, sure enough there was still a directory showing at IANSPOOL\Music\Music but it only contained a fraction of the actual files, and more importantly, it was no longer a symlink!! Does anyone have a clue what could be going on? Edit -- If it helps I've checked all the machines in my network and all have "fsutil behavior query symlinkevaluation" showing all modes set to enabled (L2L, L2R, R2L, and R2R)

Many thanx @Jonibhoni, i had come to much the same conclusion, but was hoping to avoid the "seeding" process. Oh well, nothing ventured ........ I guess I'll give it a go tomorrow

I currently have two pools, and last week due to an issue with my hardware, I needed to rearrange a lot of data (>20TB). As of this message I have all of my data on one pool, unduplicated. I'd like to make the second pool (currently empty) act as the "duplicated store", so that all the primary data is on Pool 1, and all of the duplicated data (and only duplicates) is on Pool 2. I know I can make Pool 2 a member of Pool 1, but I can't figure out what the file placement settings should be to make all the duplicates be on Pool2 and all the originals on Pool1. In effect I want Pool 2 to be a mirror of Pool 1. Is there a simple solution that I'm missing?

For a month or two, this has all been working fine. I have a pool with 11 disks, 41.8TB total size. Two of the disks are SSDs of 2TB each. Starting 2 days ago I have a single file of about 270GB which stubbornly stays on just one of the SSD's. If I try a manual balance, it just calculates then stops. Service log shows the calculation yields a Balance Ratio of .9909 and the balancing setting is 90%. Is this expected behavior? I'm slightly worried that even if one of the SSD's was completely full, these settings would not generate a balance ratio below 90% So two questions a) "does fall below 90%" mean a balance ratio of less than .9000? and b) will a balance ratio of 100% force an SSD to empty?

@umfriend - OK, the penny finally dropped, thanks. So, still not sure what my best layout is, but at least I'm pretty sure I understand the behavior better now. Much appreciate the input.

not sure what I should be setting in the Drive Usage Limiter - currently, I'm using two SSD's as cache drives for both Pool A and Pool B, and the drive limiter option has both dupllcated and unduplicated boxes checked for both SSD's.

Should have added the following observation, while setting this up, I removed one drive, and then removed a 2nd drive. Immediately, the first one was shown as "removing", while the second one was marked "Waiting to remove". Frustratingly, I then watched DrivePool happily move files from the first to the second, and then, eventually, moving everything off the second one into the rest of the Pool! Maybe the small tweak to mark the "Waiting to remove" drives as "not available to write on" would be a plan :-) Just saying .......

I have a setup at the moment that has 2 drive pools, call them Pool A and Pool B, each has it's own duplication rules and they work great! I'd like to "front-end" them with a pair of 2TB SSD's , and thought I could create a new pool consisting of the SSD's (Pool C), designate them as SSD's. i.e.non-archive, then add Pool A and Pool B as members of the front-end pool. Will this work?

Chris - not sure if this was for me or @Ragdollop. If me, then no, it's all working now.

Suddenly this morning, I cannot access folder duplication for my pools. I run 2 pools on a single Windows 10 machine. Both are on Mediasonic boxes connected by USB 3.1. There are 8 drives in each pool. Normally, I can select "Folder duplication" in the UI, and see all the folders in a given pool. This morning, I cannot see any structure, nor can I select "Change Duplication". I don't have enough space on the pools for everything to be duplicated, but DrivePool is duplicating everything right now. It will not have enough room to complete. Any suggestions? Capture1 shows the Pool view, Capture 2 show what I see when I select "Folder Protection", and Capture 3 shows what's ACTUALLY in 'BRIXPool'.

Found it. Problem with USB cable occasionally dropping out, was lucky enough to be watching when it happened, switched cables, and the disk 'box' as well. So far so good.

Not sure how recently this happened, but Drivepool is not showing the names of my pools, just a '?' This is Windows 10 Build 1903, running Beta 2.2.3.950 Drivepool Screenshot below
