Hy all of you, I'm brand new in using proxmox VE2.1 and I really appreciate this tool. I'm surfing the web to learn and find appropriate resources. I also try to organise correctly my environment. One of the first question is whereis my diskspace? I explain, I had a 500GB RAID disk and here is my command line result : root@proxmox:~# lvdisplay --- Logical volume --- LV Path /dev/pve/swap LV Name swap VG Name pve LV UUID 6hpeUQ-Id7p-8ZHb-t38K-eOP0-uFfC-N7M1wJ LV Write Access read/write LV Creation host, time proxmox, 2012-09-03 14:50:26 +0200 LV Status available # open 1 LV Size 7.00 GiB Current LE 1792 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:1 --- Logical volume --- LV Path /dev/pve/root LV Name root VG Name pve LV UUID bYw2Rk-hgku-UfK5-d54s-5pJm-YfqP-iCIcd1 LV Write Access read/write LV Creation host, time proxmox, 2012-09-03 14:50:26 +0200 LV Status available # open 1 LV Size 96.00 GiB Current LE 24576 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 --- Logical volume --- LV Path /dev/pve/data LV Name data VG Name pve LV UUID 1jWEwv-TFq7-hLjP-p9Wz-eaxB-K60K-r4LJS2 LV Write Access read/write LV Creation host, time proxmox, 2012-09-03 14:50:26 +0200 LV Status available # open 1 LV Size 345.75 GiB Current LE 88512 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2 ======================== root@proxmox:~# vgdisplay --- Volume group --- VG Name pve System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 3 Open LV 3 Max PV 0 Cur PV 1 Act PV 1 VG Size 464.75 GiB PE Size 4.00 MiB Total PE 118975 Alloc PE / Size 114880 / 448.75 GiB Free PE / Size 4095 / 16.00 GiB VG UUID sr3gR6-h1mZ-fsxC-i9j2-esTe-P3IH-Y2b1pn root@proxmox:~# df -H Filesystem Size Used Avail Use% Mounted on /dev/mapper/pve-root 102G 1.1G 96G 2% / tmpfs 4.2G 0 4.2G 0% /lib/init/rw udev 4.2G 205k 4.2G 1% /dev tmpfs 4.2G 20M 4.2G 1% /dev/shm /dev/mapper/pve-data 366G 734M 365G 1% /var/lib/vz /dev/sda1 519M 59M 434M 12% /boot /dev/fuse 32M 13k 32M 1% /etc/pve It gives us 448GB used. Is it normal that 96 Gb are used for root? Is it possible/dangerous to change this?If yes, how can I work? Then, when I read the documentation, it is explained that LVM storage is the best to use, but when I create one, I have almost no space free (see below).  Is it normal? Some posts on the are explaining that PVE already create one and it is useless to create one more if the hardware doesn't change. Is it correct? Does a new LVM storage will adapt its size dynamically so that creating a new one is relevant? What I would like to understand now is if it is correct to work with directory storage only ? Will snapshot still available if no LVM is used or does all the directory created are already "inside" the default LVM ? Should I create folders under the /var/lib/vz which is the LVM default? Thanks in advance for your answers. Regards, Florent THOMAS |
