Re: Cache configuration - changing block size

This is not as expected if defer-write was not enabled before. The process seems hung and you might have to reboot the computer. I'm sorry for this issue.

Re: Stats reset?

Yes, stats are reset on reboot. With Fast Startup enabled, when you shutdown/startup the computer, Windows means a hibernate-like/resume-like behavior, not a restart. In which case, to tell how much is in the cache, I need to look at the "Unused cache" values - if they're low it means the ...

Re: Cached files size limit

PrimoCache is a block-level caching program which tracks disk sectors, not files. There are might many files accessing the disk in the same time, so PrimoCache is kind of difficult to track each file size without the penalty of the performance. Despite these difficulties, we do keep improving the ca...

Re: L2 Primocache needed for .vhdx virtual drive hosted on another (already-cached) drive?

There was one report having the issue even without defer-write. It happened in version 3.x. Windows Storage Space creates 4Kn drives by default. We suspect that the Refs issue might be related to 4Kn drives. Now 4Kn drives have been fully supported since v4.2, so we are now running compatibility tes...

Re: Defrag - Raid HDD, L2 NVme

PrimoCache can run with most defrag programs. However, you may pause the cache to keep current cached data. Here is the link for your reference.

Re: L2 Primocache needed for .vhdx virtual drive hosted on another (already-cached) drive?

Since .vhdx file is on a drive which has already been cached, it's not necessary to cache the virtual drive. However, you may still benefit from explicitly caching virtual drives. The reason is that it can reduce IOs between virtual drives and its VHDX file. The shortage is that data might be cached...
