Linux系统挂载存储变成只读的解决方案
1、mount:用于查看哪个模块输入只读，，一般显示为：[root@localhost ~]# mount/dev/cciss/c0d0p2 on / type ext3 (rw)proc on /proc type proc (rw)sysfs on /sys type sysfs (rw)devpts on /dev/pts type devpts (rw,gid=5,mode=620)/dev/cciss/c0d0p7 on /home type ext3 (rw)/dev/cciss/c0d0p6 on /var type ext3 (rw)/dev/cciss/c0d0p3 on /usr type ext3 (rw)/dev/cciss/c0d0p1 on /boot type ext3 (rw)tmpfs on /dev/shm type tmpfs (rw)none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)/dev/dm-0 on /home/book/upload/BookFile1 type ext3 (rw)/dev/dm-1 on /home/book/upload/BookFile2 type ext3 (rw)/dev/dm-2 on /backup type ext3 (rw)/dev/dm-3 on /home/book/upload/BookFile3 type ext3 (ro)
2、如果发现有ro，就重新mount，或者umount以后再remount
3、umount /dev/dm-3
如果发现有提示“device is busy”，找到是什么进程使得他busyfuser -m /mnt/data 将会显示使用这个模块的pidfuser -mk /mnt/data 将会直接kill那个pid然后重新mount即可。
4、还有一种方法是直接remount，命令为mount -o rw,remount /mnt/data 没有用过，看到网络上有这么写。
而不去欣赏今天就开在我们窗口的玫瑰。
