Hi, Thanks Dietmar, I tested the latest pve 4.0. It seems, basically every needs are covered, congratulation :) I created a zfs storage to store virtual disks and containers. I also created a VM and an LXC container. I got the following: root@pve40 :/rpool# zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 2.30G 20.0G 140K /rpool rpool/ROOT 1.08G 20.0G 140K /rpool/ROOT rpool/ROOT/pve-1 1.08G 20.0G 1.08G / rpool/subvol-101-rootfs 293M 1.71G 293M /rpool/subvol-101-rootfs rpool/swap 953M 21.0G 116K - rpool/vm-100-disk-1 93K 20.0G 93K - Which is great, because all storages located in their own filesystem/volume by default. Manual tuning on zfs filesystems/volumes are not a big deal and can be transparent. At this moment I cannot increase the storage of the lxc container using the GUI when I put it into a zfs storage. Directory structure May I recommend to use a layout for storing zfs volumes/containers? If one creates a new zfs storage and give a name like this: ztank, it could be practical to put things under its name. Example: ztank/zvol/vm-100/vm-100-disk-1 ztank/zvol/vm-101/vm-101-disk-1 ztank/zvol/vm-101/vm-101-disk-2 ztank/lxc/vm-102/ ztank/lxc/vm-103/ With this layout, the user have a clear overview about the system and very easy to issue commands recursively. Example: zfs set compression=lz4 ztank (set lz4 compression for all storages) zfs set atime=off ztank/lxc (set atime to off for all lxc containers) or creating ad-hoc snapshot in one step (recursively). It is also very easy to copy/replicate the whole system or individual storages to a remote server using simplesnap. So, I relly like the 4.x version :) Thanks, István _______________________________________________ pve-user mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
