I've a very big problem. Today after 3 months of activity on my home server I shutdown it and restarted it. It boot in recovery mode. I see from journalctl logs that the problem was:

can't mount /home

I edited /etc/fstab and insert the 'nofail' flag under the /home row. Now it starts fine but when I try to launch the following command:

mount /home

The following error appear:

mount: /dev/mapper/centos-home: can't read superblock

Could you please help me? All worked fine before the shutdown and I could access at the /home partition Thanks Davide

I resolved the problem. If someone occurs in this problem the following command saved my life:

xfs_repair /dev/mapper/centos-home -L
