It sounds like a device-mapper issue. Everything LVM2 and device-mapper
do should be transparent to the file system.

Is / on an LVM2 volume as well? If device-mapper is having issues, I'm
not sure that a different file system would handle it any better.
However, if there were any syslog messages related to the file system
corruption or crash, they could shed some light on this.
Anyone with LVM2 experience, feel free to chime in. :-)
