Public bug reported:
Binary package hint: lvm2
Hello,
i got Ubuntu Lucid Server + openais + lvm + clvm running on a central
storage.
Metadata updates are distributed properly:
root@xen1:~# vgs
VG #PV #LV #SN Attr VSize VFree
vgsas1 1 5 0 wz--nc 1.36t 1.33t
root@xen1:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi-a- 4.00g
root@xen2:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi-a- 4.00g
root@xen1:~# lvchange -an vgsas1/play1.xxx.net-disk
root@xen1:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi--- 4.00g
NOW: Metadata obviously distributed correctly the xen2
root@xen2:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi--- 4.00g
root@xen1:~# lvchange -aey vgsas1/play1.xxx.net-disk
root@xen1:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi-a- 4.00g
NOW: LV still shown as inactive on the second node.
root@xen2:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi--- 4.00g
NOW: even better, i can activate it "exclusive" on the second node:
root@xen2:~# lvchange -aey vgsas1/play1.xxx.net-disk
root@xen2:~# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
play1.xxx.net-disk vgsas1 -wi-a- 4.00g
I can even mount it from both nodes:
root@xen2:~# mount /dev/vgsas1/play1.xxx.net-disk /mnt/
root@xen2:~# df

AND ON:

root@xen1:~# df

If that was no test setting but 2 vm's accessing one ext3 fs simultaneously, I
would be in serious trouble now!
btw, the Clvm was recompiled against openais to get rid of cman.
root@xen1:~# dpkg --list|grep lvm
ii clvm 2.02.54-1ubuntu4.2
Cluster LVM Daemon for lvm2
ii lvm2 2.02.54-1ubuntu4.1
The Linux Logical Volume Manager
