I'm seeing a lot of messages about snapshots sort of working... I should relay my experience here. I did some testing with Snapshots in 2.6.8.1, and came up with variable results. Here's some stuff I found: reiserfs works badly with read/write snapshots: writing to both the main filesystem and the snapshot hangs the filesystems permanently (even after writing stops), and stops LVM from being able to assign more snapshots/space/etc until a full reboot. ext3 works OK, albeheit with a definite CPU hit. I tried low-level loads and it didn't crash, which was certainly better than with reiserfs. I didn't try a whole lot of other filesystems though. Generally, it didn't seem quite stable enough, so I decided to wait a few iterations before working with it seriously. Does anyone know the status of work in this area? Or if there's some more patches waiting in -mm?
