Please post the output of mount. –  schaiba Mar 3 '13 at 12:06
mount displays /etc/mtab, which can be out of sync with the reality (for instance when the FS has been remounted ro because of errors). What about grep /opt/nls/float /proc/mounts and look in dmesg output for errors related to the corresponding dm-x device? –  Stéphane Chazelas Mar 3 '13 at 14:26
