I have a strange problem with my centos7 file server. I have a large
data storage (75TB in RAID6, managed by lvm) and each night I create a
snapshot  (removing first the previous one). The snapshot is mounted
read-only so if a user remove a file accidentally he can restore it in
the same day. However, if this snapshot exists, reboot of the server
freeze at boot time and I must manually remove this snapshot. Why ?
There are no entry in /etc/fstab for this snapshot, it is a cron script 
that manage this snapshot and mount it.
