Hi,
thanks for the answer. No I don't use clustered LVM. I tried to do
deactivating and activating from the second node (client01) but
nothing changed:
client01:~# vgscan
Reading all physical volumes. This may take a while...
Found volume group "pve" using metadata type lvm2
Found volume group "replicated" using metadata type lvm2
client01:~# vgchange -an
Can't deactivate volume group "pve" with 4 open logical volume(s)
client01:~# vgchange -an replicated
0 logical volume(s) in volume group "replicated" now active
client01:~# vgscan
Reading all physical volumes. This may take a while...
Found volume group "pve" using metadata type lvm2
Found volume group "replicated" using metadata type lvm2
client01:~# vgchange -ay replicated
2 logical volume(s) in volume group "replicated" now active
client01:~# lvdisplay
output shows just local lv's
---------------------------------------
If I do lvdisplay on the first node (client00) I see the local LV's
and the DRBD-LV's:
--- Logical volume ---
LV Name /dev/replicated/vm-101-disk-1
VG Name replicated
LV UUID i7NM1a-heRf-ZufV-5pVJ-NsU8-0xHh-d2vALH
LV Write Access read/write
LV Status available
# open 0
LV Size 10.00 GB
Current LE 2560
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:4
--- Logical volume ---
LV Name /dev/replicated/vm-104-disk-1
VG Name replicated
LV UUID eEdV1h-42uJ-GH56-o0f8-Nk2i-DaMm-G1er2X
LV Write Access read/write
LV Status available
# open 0
LV Size 20.00 GB
Current LE 5120
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:5
I think it should work without clustered LVM?
Best regards,
Markus
Zitat von David Coulson <[email protected]>:
Are you using clustered LVM? If not, you probably should be.
You could try deactivating the VG then reactivating it and seeing if
the new primary sees the LV.

Dear all,
I want to build an HA setup with virtual machines on a two hardware
node setup. I already setup a nested LVM DRBD configuration. But
from the second node I can't see the lv's from the drbd device;
pvscan displays it.
Has anybody an idea whats wrong with my setup? I think I need a
primary/primary drbd device because if one hardware node fails I
want to start the KVM container from the other one; therefore I
need the latest data of the KVM container.
Please find some logs below...
Thanks a lot for your help in advance!
Best regards,
Markus
