一. Centos 7 LVM xfs文件系统修复
情况1

ls -l /dev/mapperxfs_repair /dev/mapper/cl_muban-root若提示 xfs_repair -L /dev/mapper/cl_muban-root最后重启

ls -l /dev/mappermkdir /mntmount /dev/mapper/cl_muban-root /mnt # 这里也可以操作 提示中的 dm-0 (即 /dev/dm-0其实/dev/mapper/cl_muban-root是链接到 /dev/dm-0 )umount /mntxfs_repair /dev/mapper/cl_muban-root # 或 xfs_repair /dev/dm-0init 6 (reboot重启系统)xfs_repair使用方法
xfs_repair -h
xfs_repair: invalid option -- h
Usage: xfs_repair [options] deviceOptions:
-f The device is a file
-L Force log zeroing. Do this as a last resort.
-l logdev Specifies the device where the external log resides.
-m maxmem Maximum amount of memory to be used in megabytes.
-n No modify mode, just checks the filesystem for damage.
-P Disables prefetching.
-r rtdev Specifies the device where the realtime section resides.
-v Verbose output.
-c subopts Change filesystem parameters - use xfs_admin.
-o subopts Override default behaviour, refer to man page.
-t interval Reporting interval in minutes.
-d Repair dangerously.
-V Reports version and exits.二. Centos7终端显示-bash-4.2#解决方法
重启进入Linux系统后发现显示的是-bash-4.2# 而不是root主机名 路径的显示方式发生这种情况的原因是根目录下缺失几个配置文件从默认配置中拷贝过来就可以解决了
cp /etc/skel/.bashrc /root/
cp /etc/skel/.bash_profile /root/\quad\quad如果为虚机且有快照的话恢复快照有时也可以解决 林肯公园
