The snapshot is accomplished using the following commands:
lvcreate -s hypervisor/KVM_Storage --name Backup_SNAP
lvchange -ay -K hypervisor/Backup_SNAP
mount -o nouuid /dev/hypervisor/Backup_SNAP /mnt/lvm/
You need to use xfs_freeze to make the filesystem coherent before
snapshot:
xfs_freeze /dev/hypervisor/KVM_Storage
lvcreate -s hypervisor/KVM_Storage --name Backup_SNAP
xfs_freeze -u /dev/hypervisor/KVM_Storage
lvchange -ay -K hypervisor/Backup_SNAP
It was my understanding that filesystem freezing was automatically
managed by LVM, and integrated into VFS long ago.
I am missing something?
