centos7 斷電導致 generating /run/initramfs/rdsosreport.txt 問題
物理斷電，有時候會出現
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。
處理步驟:
xfs_repair /dev/mapper/centos-root 或者xfs_repair /dev/mapper/centos-root -L
兩個命令不一定哪個能成功，第一個不行就試下第二個。
最后reboot就行了
