Opinions on internal disk allocations/assignments

[bond347]

Hi All,

I want to get some thoughts/opinions from you guys with regard to my internal disk allocations.

My server has:
RAID1 (2x 240GB) - sdb
RAID5 (3x 1.9TB) - sda

root# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 3.5T 0 disk ├─data2-data2_tmeta 253:0 0 15.8G 0 lvm │ └─data2-data2 253:7 0 3.5T 0 lvm └─data2-data2_tdata 253:1 0 3.5T 0 lvm └─data2-data2 253:7 0 3.5T 0 lvm sdb 8:16 0 223.5G 0 disk ├─sdb1 8:17 0 1007K 0 part ├─sdb2 8:18 0 512M 0 part /boot/efi └─sdb3 8:19 0 223G 0 part ├─pve-swap 253:2 0 8G 0 lvm [SWAP] ├─pve-root 253:3 0 65.8G 0 lvm / ├─pve-data_tmeta 253:4 0 1.3G 0 lvm │ └─pve-data 253:6 0 130.6G 0 lvm └─pve-data_tdata 253:5 0 130.6G 0 lvm └─pve-data 253:6 0 130.6G 0 lvm root# pvs PV VG Fmt Attr PSize PFree /dev/sda data2 lvm2 a-- 3.49t 512.00m /dev/sdb3 pve lvm2 a-- 223.00g 15.99g root# vgs VG #PV #LV #SN Attr VSize VFree data2 1 1 0 wz--n- 3.49t 512.00m pve 1 3 0 wz--n- 223.00g 15.99g root# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert data2 data2 twi-a-tz-- 3.46t 0.00 0.19 data pve twi-a-tz-- <130.59g 0.00 1.22 root pve -wi-ao---- 65.75g swap pve -wi-ao---- 8.00g

1. Login to the porxmox portal and i can only see 2 storages called "local" and "local-lvm". Where is the data2 volume?
2. There were 2 VGs created automatically after the installation. Should i combine both sda and sdb into the pve volume group?
3. I plan to delete the data volume (130G) and use that space to grow the root volume.
4. How can i create 2 LVs, one called data (thin provision) for VMs and containers and another lv called backup for backups, iso and etc.?

Hope experts can help me out.

ad 1.) Only vg "pve" and lv "data" in it is configured implicitly as Storage. Other LVM Storages have to configured by GUI with "Datacenter" -> "Storage" -> "Add" -> "LVM"

ad 2.) No, since sda and sbd have quite different physical attribues

ad 3.) No problem: first delete the Storage by "Datacenter" -> "Storage" -> "local-lvm" -> "Remove"; afterwards delete the lvm itself by "lvremove" and extend the root lv instead by "lvextend"

ad 4.) AFAICS you have currently (after performing step 3) only lv "data2" and "root" which occupies the capacity of the two pvs completely. Solution would be e.g. (other variants possible) to create a thin pool in "data2" and afterwards use this thin pool on one hand for VM virtual disks (create a Storage by "Datacenter" -> "Storage" -> "Add" -> "LVM-Thin") and on the other create an lvm in this pool with a filesystem mounted and define the respective directory as Storage for backups, ISO, etc. by "Datacenter" -> "Storage" -> "Add" -> "Directory"
