LVM logical volume and rescan/redetect feature

[pfoo]

Is there any way to force proxmox 2.1 to rescan all logical volume stored in his database ?

My issue is that I created manually a lv using lvcreate and added it manually to the vm (qemu) config file. While the vm boot juste fine (and the disk is accessible), this particular LV is not displayed in proxmox LV list (gui or pvesm list)

For instance :
I created /dev/main/vm-106-disk1 manually.

# lvdisplay /dev/main/vm-106-disk-1 
  --- Logical volume ---
  LV Path                /dev/main/vm-106-disk-1
  LV Name                vm-106-disk-1
  VG Name                main
  LV UUID                3b4wrk-sEh5-hTcX-iC5q-FqBY-lsnp-sWYoJT
  LV Write Access        read/write
  LV Creation host, time proxmox, 2012-07-15 17:38:55 +0200
  LV Status              available
  # open                 0
  LV Size                30.00 GiB
  Current LE             7680
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           253:4

Here is my vm config file

# cat /etc/pve/qemu-server/106.conf 
args: -serial unix:/var/run/qemu-server/106.serial,server,nowait
bootdisk: virtio0
cores: 2
ide2: local:iso/rescue_amd64.iso,media=cdrom,size=137M
memory: 1024
name: orion
net0: rtl8139=42:01:22:B8:E6:DF,bridge=vmbr2
ostype: l26
sockets: 1
virtio0: data:vm-106-disk-1,size=30G

And finally, pvesm list

# pvesm list data
data:vm-100-disk-1   raw 2147483648 100
data:vm-102-disk-1   raw 21474836480 102
data:vm-103-disk-1   raw 53687091200 103
data:vm-104-disk-1   raw 53687091200 104
data:vm-105-disk-1   raw 214748364800 105

As you can see, vm-106-disk-1 is not displayed here.

Is there any way to tell proxmox to redetect all lv, or to add it manually ?

I already tried to disabled/enable the storage, but no luck

Please can you post the storage configuration (/etc/pve/storage.cfg)

 

[pfoo]

# cat /etc/pve/storage.cfg
dir: local
path /var/lib/vz
content iso,vztmpl,backup,rootdir

lvm: data
vgname main
content images
nodes proxmox

any updates on this ?

We implemented a new 'qm rescan' command (you need to update to latest available packages, the run

# qm rescan

or (if you want to fix a specific VM)

# qm rescan --vmid <VMID>

Hi,
I assume, you forget the right tag for the logical volume. Do simply an

lvs --options 'vg_name,lv_name,lv_size,tags'
lvchange --addtag pve-vm-106 /dev/main/vm-106-disk-1
lvs --options 'vg_name,lv_name,lv_size,tags'

Perhaps "qm rescan" do the same...

Mh, that was it actually. Thanks !
