1 | STORAGE Design: |
| 2 | =============== | |
| 3 | ||
| 4 | pool: ability to create more than one volume | |
| 5 | ||
| 6 | - directory (NFS server, local dir) | |
| 7 | ||
| 8 | - LVM group | |
| 9 | ||
| 10 | - physical disk (partitions) ?? | |
| 11 | ||
| 12 | - ISCSI volume pools ?? | |
| 13 | ||
| 14 | - qemu base image ?? | |
| 15 | ||
| 16 | a pool can support several formats (raw, qcow2, vmdk, ...) | |
| 17 | ||
| 18 | volume: can be used for VM storage | |
| 19 | ||
| 20 | - block device | |
| 21 | ||
| 22 | - file (raw, qcow2, ...) | |
| 23 | ||
| 24 | - ISCSI LUN | |
| 25 | ||
| 26 | A pool is either shared of local. The resulting volume | |
| 27 | inherits that property. | |
| 28 | ||
| 29 | ||
| 30 | lvs --separator , --noheadings --units b --unbuffered --nosuffix --options "lv_name,uuid,devices,seg_size,vg_extent_size" | |
| 31 | ||
| 32 | pvs --noheadings -o pv_name,vg_name | |
| 33 | ||
| 34 | vgs --separator : --noheadings --units b --unbuffered --nosuffix --options "vg_size,vg_free" VGNAME | |
| 35 | ||
| 36 | ||
| 37 | What about ISO/template storage? | |
| 38 | ||
| 39 | Storage Configuration: | |
| 40 | ====================== | |
| 41 | ||
| 42 | /etc/pve/storage.shared | |
| 43 | /etc/pve/storage.local | |
| 44 | ||
| 45 | oder | |
| 46 | ||
| 47 | /etc/pve/storage.config | |
| 48 | ||
| 49 | mit node attribute for jeden pool. | |
| 50 | ||
| 51 | jedes volume kann einen owner haben (VMID)?? | |
| 52 | ||
| 53 | ||
| 54 | Aus einem pool werden volumes generiert. Jedes volume is einer VMID zugeordnet, entweder | |
