Hi, I have the original filesystem (on a logical volume) "intact" because I've always worked on snapshots. The filesystem has less than 2^31 blocks. This system has been correctly running for four years and corruption become because of a hardware problem with a SAN device. The output of dumpe2fs -h /dev/storage/cabina is: dumpe2fs 1.41.9 (22-Aug-2009) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: 607db553-3dc2-4304-9059-37eb99f1047b Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal resize_inode filetype sparse_super large_file Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean with errors Errors behavior: Continue Filesystem OS type: Linux Inode count: 1038548992 Block count: 2077085696 Reserved block count: 0 Free blocks: 220295654 Free inodes: 1004004295 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 877 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 16384 Inode blocks per group: 512 Filesystem created: Fri Jul 7 16:45:37 2006 Last mount time: Wed Jan 20 11:53:00 2010 Last write time: Thu Feb 11 10:16:13 2010 Mount count: 65 Maximum mount count: 35 Last checked: Sat Jul 15 05:53:09 2006 Check interval: 15552000 (6 months) Next check after: Thu Jan 11 04:53:09 2007 Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 128 Journal inode: 8 Default directory hash: tea Directory Hash Seed: 94a8b51f-6ba4-484d-bb92-167cb75c3eb6 Journal backup: inode blocks Journal size: 32M Thanks you! > What is the blocksize of your filesystem?
