Package e2scrub

Online Ext4 metadata consistency checking tool and service

http://e2fsprogs.sourceforge.net/

This package includes e2scrub script that can check ext[234] file system
metadata consistency while the file system is online. It also containes a
systemd service that can be enabled to do consistency check periodically.

The file system consistency check can be performed online and does not
require the file system to be unmounted. It uses lvm snapshots to do this
which means that it can only be done on file systems that are on a lvm
managed device with some free space available in respective volume group.
