Sreyan> I have migrated to thin pools using partclone.
I suspect you're toast. What are you trying to accomplish here though? Trying to stuff 10 pounds of data into a 5 pound bag? *grin* Or are you trying to have the ability to take snapshots of your system to make rollbacks easier? Sreyan> But now that I am using thin pools my system is completely unstable. You need to post the output of your configuration in more detail, with dmesg output, logs, lvs, pvs, vgs output, etc. But really, you do have backups?
