I am fscking a lustre OST lun, and it shows the following: [root@oss4 ~]# e2fsck -f -C 0 /dev/mapper/mpath7 e2fsck 1.42.3.wc1 (28-May-2012) Pass 1: Checking inodes, blocks, and sizes Inode 192820368, i_blocks is 15512, should be 4294982808. Fix? yes Pass 2: Checking directory structure i_blocks_hi for inode 192820368 (/O/0/d0/42065024) is 1, should be zero. Clear? yes Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information nobackup-OST001b: ***** FILE SYSTEM WAS MODIFIED ***** nobackup-OST001b: 1756205/477626368 files (5.6% non-contiguous), 1529484010/1910505472 blocks I have run fsck twice and the same error with that same inode appeared both times and worries me, why when I say to clear it it doesn't really clear. Any thought on this? Brock Palen www.umich.edu/~brockp CAEN Advanced Computing brockp(a)umich.edu (734)936-1985
