What could I do with Centos 7?

Question

CentOS

Good afternoon. Turned off the light, after loading it started in emergency mode and reports a problem in the dm-0 partition.
I looked at all the partitions,
cat /proc/partitions
then I did it
xfs_repair -L /dev/dm-0
and the system started up, cheers! But a little later I understand that the network is not working. Ping'a does not respond.
ping 8.8.8.8
And Gateway responds. I did not change any settings, it makes no sense to watch them. There is a suspicion that I did something important in the heat of umount, I tried to do this command several times.
What do you advise? How to mount everything back? mount -a did not help.

Answer 1

Uraaaaa, it started up the second time. mount -a and service network restart.
