I believe more in a crash of xfs than a hardware failure (like we had on 
According to lvm, system have multipath for storage and multipath looks 
like fine, root filesystem too.

I've forced a reboot and system came back online with /home mounted. 
dmesg show an xfs recovery.
[   12.608593] XFS (dm-6): Mounting V4 Filesystem
[   12.841363] XFS (dm-6): Starting recovery (logdev: internal)
[   29.126997] XFS (dm-6): Ending recovery (logdev: internal)

I perform an xfs_repair to be sure, xfs looks like ok… for now.

In case the error came back again, we may try to switch to ext4 (this 
will imply loosing all data).
