It's part of Linux-LVM since version 0.8 and thus part of Linux 2.4. Christoph -- Of course it doesn't work. We've performed a software upgrade. |

Unfortunately the 0.8 variant of it was not very usable, because snapshots were read-only (thus making it impossible to run fsck or replay a log) 0.9 should have writable snapshots, still non persistent over reboots though. -Andi |

You need to get the recent LVM 0.9.1 Beta 7 software *and* to patch your kernel as well, because that'll fix some snapshot related flaws. > > Christoph > > -- > Of course it doesn't work.
