Hello, I use flashcache to speed up my storage. It works great, however I noticed that VZDump can't make a LVM snapshot. This is my setup: MDADM 4x 2TB eco disk in RAID5 = /dev/md0 MDADM 2x 160GB SSD in RAID1 = /dev/md1 Created a LVM VG "PVE" on /dev/md0 Created a LVM LV "DATA" = /dev/mapper/pve-data Created a ext3 filesystem on /dev/mapper/pve-data (till now it works if I use snapshot back-ups) Now I setup flashcache flashcache -p thru ssd /dev/md1 /dev/md0 Flashcache is loaded and a new disk name appears = /dev/mapper/ssd If I mount /dev/mapper/ssd it won't let me create snapshots. If I create a snapshot on /dev/mapper/pve-data (even when SSD is mounted) it works. Is there some way I can trigger vzdump to use /dev/mapper/pve-data (the underlying LVM volume of flashcache)?
