Hi, 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. Patrick
