[pve-devel] lvm cache file missing ?

[Alexandre DERUMIER]

with the flag to 0, yes, i have the .cache file.

but in cache file, I have all devices existing in /dev/ and not only devices with lvm volumes...

I had attached the cache file to this email.

But udev also handle such list, so I guess that should be also fast. 

If you set that flag to 0, you will get the old .cache file?
