Hi, There was three bad btree nodes: Dec 20 16:12:08 yf237 kernel: NILFS: bad btree node (blocknr=710153406): level = 0, flags = 0x2, nchildren = 25088 Dec 20 16:12:08 yf237 kernel: NILFS error (device sdb2): nilfs_bmap_last_key: broken bmap (inode number=321775) -- Dec 21 10:10:07 yf237 kernel: NILFS: bad btree node (blocknr=711343917): level = 199, flags = 0x60, nchildren = 16670 Dec 21 10:10:07 yf237 kernel: NILFS error (device sdb2): nilfs_bmap_last_key: broken bmap (inode number=324685) -- Dec 21 10:13:41 yf237 kernel: NILFS: bad btree node (blocknr=14167806): level = 0, flags = 0x0, nchildren = 0 Dec 21 10:13:41 yf237 kernel: NILFS error (device sdb2): nilfs_bmap_last_key: broken bmap (inode number=253710) I have not found new bad btree nodes in recent days. But the MyISAM tables still often be crashed and soon be ok without repairing. 在 2012-12-28,14:06,Vyacheslav Dubeyko <slava@xxxxxxxxxxx> 写道: > Hi, > > On Thu, 2012-12-27 at 17:47 +0800, Elmer Zhang wrote: >> Hi konishi ryusuke, >> >> I am trying to use NILFS2 to make MySQL cold backup, but the MySQL tables often be crashed.
