Hi there. I'm trying to set up HA-Cluster on Fedora with Red Had Cluster Suite.
I've already set up cman and it works.
Now, I want to create shared strorage with clvm+gfs2. I've install lvm2-cluster. Made
lvmconf --enable-cluster. And now:
I have 2 nodes, clvmd started:
on 1st node I've done:
%# pvcreate /dev/sdb1
on 2nd node I've done:
%# pvcreate /dev/sdb1
As you may see, there are /dev/sdb1 device, but it's not the same machine - it's 2 different devices.
on 1st node I've done:
%# vgcreate shared /dev/sdb1
"shared" is a name for volume group.
In current step, I'm now created volume group on 2nd node.
on 1st node I've executed:
%# lvcreate -l 254 -n shared shared
But, it failed with error:
Error locking on node <2nd node name>: Volume group for uuid not found: QgSZ5Y8KWOxxbxYdk4Y0eOoJh8GwP1hv9GTrlwNycTk7xWBejIp0suFANorVEuKS
Aborting. Failed to activate new LV to wipe the start of it.
Then, I've created volume group "shared" on 2nd node:
%# vgcreate shared /dev/sdb1
And then on 1st node, I've executed lvcreate once more, but have the same error.
What am I doing wrong? I'm really newbie in clvm, but expierenced user of plain lvm, so, I have questions.
My vgdisplay of 1st node:
%# vgdisplay
--- Volume group ---
VG Name shared
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 27
VG Access read/write
VG Status resizable
Clustered yes
Shared no
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 1016.00 MB
PE Size 4.00 MB
Total PE 254
Alloc PE / Size 0 / 0
Free PE / Size 254 / 1016.00 MB
VG UUID QgSZ5Y-8KWO-xxbx-Ydk4-Y0eO-oJh8-GwP1hv
On second node, there are either no volume groups or one named shared with just different VG UUID.
