And my SSD have a firmware issue that prevents me from using it at the moment. Since Leap 15.3 has libblockedv 2.25, I hope someone can confirm it whether this issue is really gone or not. Now, the packaging problem is already in progress to be fixed in Factory. The Maintenance Team will have a look at the viability of updating the package in Leap 15.3. I don't know how exactly works the inheritance of SLE packages to Leap, have we already reached the deadline for revising package versions for 15.4? -- You are receiving this mail because: You are on the CC list for the bug.

I'm going to try replicate this in a VM and report upstream. Thanks for the information so far. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1183948 http://bugzilla.opensuse.org/show_bug.cgi?id=1183948#c8 --- Comment #8 from Luciano Santos --- I had a break through this week. After sweating a little to edit LVM2's specfile and switch on D-Bus support. Now I'm able to get the following error: "Failed to get stats for '/dev/system/root': The object with LVM ID '/dev/system/root' doesn't exist" Rather than getting the old error: "Failed to get stats for '/dev/sysem/root': Failed to create DM task for the cache map '-dev/system/root'". Since and don't have any cached volumes here I'm taking that as an auspicious sign. Now, I'm gonna see about branching Leap 15.3's LVM2-2.03.05 and making the changes I did for my Tumbleweed's LVM2-2.03.12 branched package. Once I do this, would you be willing to test the package? I don't know in what kind of setup you're running the cached volumes, whether it's a production server or not. -- You are receiving this mail because: You are on the CC list for the bug.

I can try, it's desktop client, I will make a virtualmachine so I can try without >any problem... tumpleweed or 15.3?

Whoa! I didn't know one could use cached volume in a VM. How that works, via USB? (Just out of curiosity). Well, you could first try on Tumbleweed then since it's already built for it. You can basically do: geeko~> sudo zypper ar -cfp 90 https://download.opensuse.org/repositories/home:/luc14n0:/LVM/openSUSE_Tumbl... home:luc14n0:lvm && sudo zypper ref -r home:luc14n0:lvm && zypper dup --from home:luc14n0:lvm --allow-vendor-change Succeeding the installation, just reboot. Don't forget to start LVM's D-Bus with: geeko~> sudo systemctl start lvm2-lvmdbusd.service Now we cross our fingers and try `lvm-cache-stats` once again :~) -- You are receiving this mail because: You are on the CC list for the bug.
