错误信息，求助！

今天启动时看到有警告信息，后来dmesg看了下，如下：
REISERFS (device sda8): found reiserfs format "3.6" with standard journal
REISERFS (device sda8): using ordered data mode
REISERFS (device sda8): journal params: device sda8, size 8192, journal first block 18, max trans len 1024, max batch 900, max commit age 30, max trans age 30
REISERFS (device sda8): checking transaction log (sda8)
REISERFS warning: reiserfs-5090 is_tree_node: node level 387 does not match to the expected one 1
REISERFS error (device sda8): vs-5150 search_by_key: invalid format found in block 722305. Fsck?
REISERFS (device sda8): Remounting filesystem read-only
REISERFS error (device sda8): vs-13070 reiserfs_read_locked_inode: i/o failure occurred trying to find stat data of [1 2 0x0 SD]
REISERFS (device sda8): Using r5 hash to sort names
不能肯定是什么问题，是文件系统问题还是硬盘硬件问题？fsck.reiserfs一下，提示提：3 found corruptions can be fixed only when running with --rebuild-tree
汗，我又加了--rebuild-tree参数试图修复，在输入YES前看了看程序的警告，不敢继续试了。

直接格了一次reiserfs,好了！
