Re: [Xen-users] Error with clvm

[Guy Roussin <guy.roussin@xxxxxxxxxxxxxxxx>]

Hi,

I can now access again to my lvm.
1) I remove the word in the file /etc/lvm/backup/vg0
status = ["RESIZEABLE", "READ", "WRITE", "CLUSTERED"]
=>
status = ["RESIZEABLE", "READ", "WRITE"]
2) I downgrade the locking_type in /etc/lvm/lvm.conf
locking_type = 3
=>
locking_type = 1
3) I restore my vg with
vgcfgrestore vg0

I can locally use my LVs without problem.

*But i can't anymore use it with clvm* :
1)
vgchange -cy vg0
2)
locking_type = 3

and when i /etc/init.d/clvm restart i get :

CLVMD[40800950]: Mar 12 16:38:10 LVM thread waiting for work

Thank you,


Guy
