Hi list.
I am dealing with DRBD (+GFS as its DLM). GFS configuration needs a CLVMD configuration. So, after syncronized my (two) /dev/drbd0 block devices, I start the clvmd service and try to create a clustered logical volume. I get this:
On "alice":
[root@alice ~]# pvcreate /dev/drbd0 Physical volume "/dev/drbd0" successfully created [root@alice ~]# vgcreate testvol /dev/drbd0 Clustered volume group "testvol" successfully created [root@alice ~]# vgdisplay --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 15.88 GB PE Size 32.00 MB Total PE 508 Alloc PE / Size 508 / 15.88 GB Free PE / Size 0 / 0 VG UUID xFelou-Bh1z-PjqE-A01S-rRDc-lOhF-PDLb30

Failed to activate new LV to wipe the start of it.
On "bob":
[root@bob ~]# vgscan Reading all physical volumes. This may take a while... Found volume group "VolGroup00" using metadata type lvm2
What's going on? Should I have a "testvol" also on bob? Why can't I create a logical volume?
Thanks for anyone will reply.
