You set up your machine with LVM and with software (mdadm) RAIDto ensure your data is safe.Then something goes wrong..Now what do you do?This shows you how.

Mikulas Patocka announced new patches introducing snapshot merging for the Linux kernel's logical volume manager.

He explained, "snapshot merging allows you to merge snapshot content back into the original device. The most useful use for this feature is the possibility to rollback [the] state of the whole computer after [a] failed package upgrade, [or an] administrator's error".

The patches are for the 2.6.26 kernel, with device mapper 1.02.27 and LVM2.2.02.39.
