I just ran fsck and this is the result. [root@node9-0 ~]# fsck -f /dev/sdb1 fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/sdb1: 800/122101760 files (34.6% non-contiguous), 10295560/488378368 blocks
