zfs-windows-2.2.6-rc5

[lundman]

I posted the rc5 build, it deals mostly with snapshot mounting BSODs.

Please report your findings here, if your bugs are still active, can you mention the bug ID in here for me thanks.

OK changing driveletter from E: to Y: (ie, from driveletter to a different driveletter) does not work. Code sees it is a driveletter and is happy. It does not check it is the desired driveletter

[lundman]

Like an idiot, I updated VisualStudio and now I can't deploy - which makes debugging a pain. I've informed MS, but meanwhile, I have to load it manually which makes me stabby. :)

If you work in a VM, you probably didn't make a snapshot before the upgrade, right?

[lundman]

TargetVM I always use snapshots, so that didn't change. HostVM I do not. Been trying many things, including downloading the latest Windows Development VM, and configuring remote target. Also errors. The latest versions are just broken.

[sskras]

Yes, I meant HostVM (AKA BuildVM).

[lundman]

I tried two brand newly downloaded Windows Development VMs, and they can't deploy either, so they just broke it. Anyway, I have a manual way to deploy for now, it's not great but works. At least we are still moving forwards.

OK starting to look good, assigning marginal trust to new mount code.

No leaks, no forced closed vnodes. I'm sure there are corner cases but a good start
