Just a quick question: Is there a stable DM mirror target for 2.6? More detail (in case I'm being silly and don't need the mirror target): I got the following error from pvmove: "device-mapper ioctl cmd 9 failed: Invalid argument" And from the LVM mailing list archives I found that I need the DM mirror target to use pvmove in LVM2. The kernel I'm using (debian testing's 2.6.3-1-k7) does not have a mirror target module or an option in the kernel source. I found some kernel patches here: http://people.sistina.com/~thornber/patches/ But there is not very much documentation on the status of this code. Have other LVM2 users had good experiences with the mirror target patches available in the 2.6-unstable/ directory? Thanks for your time, Rupert
