How to fix and manage data in rescue mode?
Hello,
I am running ubuntu 14.04
My server has problems again. I need to manage system files in rescue mode, backup some files, edit /etc/crontab and rc.local files etc.

Code:
root@rescue:~# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
md2 : active raid1 sda2[0] sdb2[1]
      4193216 blocks [2/2] [UU]

md3 : active raid0 sda3[0] sdb3[1]
      7787813888 blocks 512k chunks

unused devices: <none>



Code:
root@rescue:~# fdisk -l
