Today, due to the non-normal computer shut down, resulting in the virtual machine file system, such as newspaper:
generating “/run/initramfs/rdsosreport.txt”
entering emergencymode.
exit the shell to continue
type “journalctl” to view system logs.
you might want to save “/run/initramfs/rdsosreport.txt” to a usb stick or /boot after mounting them and attach it to a bug report。这样的错误。
After Baidu to solve the problem that the solution is very nice! ! ! Pretending this note, summarizing and sharing.
Repair steps:
"1" ls -l / dev / mapper
"2" mkdir / mnt
"3" mount / dev / mapper / cl_muban-root / mnt # Here you can also operate dm-0 in the prompt (ie, / dev / dm-0, in fact, / dev / mapper / cl_muban-root is a link to / dev / dm -0)
Or mount / dev / dm-0 / mnt
《4》 umount /mnt
《5》 xfs_repair /dev/mapper/cl_muban-root 或 xfs_repair /dev/dm-0
"6" init 6 (reboot the system directly reboot)
Repair command xfs_repair:
xfs_repair -h xfs_repair: invalid option -- 'h' Usage: xfs_repair [options] device Options: -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.
Although this problem solved, but know these, but do not know why, should again return late.
