Mount shows 3 filesystems duplicated

[Bad2theBone]

Not sure exactly where this fits in and I find it a little strange but it started this morning when I had left my system for about an hour, came back and found that it was frozen. The cursor was unresponsive to the mouse and keyboard. I finally wound up hitting reset and found that /var was full about 8GB. I doubled the size of the lv for /var to 16GB and all seemed to be happy. Later this evening I did a df -vh to check all filesystems space and noticed that it reported /home, /tmp, and /var twice. Also space used for /var was back to less than 2GB. I had earlier tried to find what was eating up space, but found nothing.

I then checked my fstab to see if there were duplicate entries but none listed, however mount shows duplication for those 3 filesystems. I am using LVM on top of LUKS and the 3 filesstems are on their own lvs but on the same vg. I am running F 15 since 6/3/11. I had before this enlarged the lv that has /home yesterday.

Anyone have an idea as to what may be happening?
