Repair the file system, the following error occurs, and abnormal termination: Not a recognized filesystem type. To solve this problem, only with the ultimate backup to restore the main block of the ultimate block, and we all know, in the document system, 1 ultimate logic block is the main block, 31 blocks of logic block is the ultimate backup, so put the logic block 31, No. 1 on the contents of the write logic block up. For example, the corresponding logical volume file system to / dev/lv1, restore the file system is the ultimate block commands are as follows: When restore is complete, we must use the fsck command to check file system integrity: ** Checking / dev/rlv1 ** Phase 0 - Check Log log redo processing for / dev/rlv00 ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference counts ** Phase 5 - Check Inode Map ** Phase 6 - Check Block Map 9 files 608 blocks 15776 free
IBM on the open source communitys comments a lot of weight, IBM has invested heavily for the Linux operating system, and for the Linux operating system has made tremendous contributions. Since December 2000, IBM on even behind the Linux operating system; 2001, IBM committed to Linux operating system, invest 10 billion U.S. dollars. Souters "prophecy" is more like IBM for Linux within the next decade that a change in the total sign. Linux developers should be concerned is to make the Linux operating system more green in their process more efficient use of resources in order to reduce data center energy consumption. Currently, even server virtualization, load balancing, improve resource management and other technology can improve the efficiency of the Linux operating system. Souter said: "The Linux operating system can improve the efficiency of the way as well. I always think that open source is not enough work to do." Souter pointed out that the Linux open source community on how to improve efficiency and no brains. Medium and small enterprises to the Linux market offers tremendous business opportunities. That the free operating system that can help small and medium enterprises to reduce costs, but also medium and small companies need not maintain the "all-inclusive application."
