I also tried the instructions in http://forums.debian.net/viewtopic.php?f=5t=119644 but still cannot reboot into cached hdd system removing the cache (lvremove lvcache) every time I fail to boot, by using a rescue usb, gave me some corruption and was just inconvenient to further experiment. so I ended up giving up until someone else succeeds using lvmcache. My use would be a laptop with a small ssd 24GB drive and I think this would be a cool way to speed up the system. actually it was intended for that and the MS windows system did that before I wiped it out. Setting up the lvm and installing ubuntu was easy, setting up the lvmcache was easy too... but couldn't manage to make it boot :/ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1423796 Title: Unable to mount lvmcache root device at boot time Status in initramfs-tools package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in lvm2 package in Ubuntu: Confirmed Bug description: I'm experimenting with Vivid Vervet on a virtual machine and tried a new LVM feature, lvmcache.
