Hi Shalom, Are you still facing problem implementing HA-LVM with locking_type = 3 setting ?. If yes, it would be great if you could provide the following details . So that others can also check
* steps you are following along with complete output * status in "clustat" after making changes in cluster.conf * attach cluster.conf and /var/log/messages. dominic On Fri, Feb 4, 2011 at 8:34 PM, שלום קלמר <[email protected]> wrote: > Thanks. > > This is the old methos and its work great but its hard to maintain such > cluster. > > Shalom. > > > On Fri, Feb 4, 2011 at 4:32 PM, Dominic Geevarghese > <[email protected]>wrote: > >> >> Hi, >> >> I am not sure about the error you are getting but it would be great if you >> could try the preferred method >> >> locking_type = 1 >> volume_list [ "your-root-vg-name" , "@hostname" ] >> >> rebuild initrd >> >> add the <lvm> and <fs> resources in cluster.conf , start the cman, >> rgmanager . >> >> >> Thanks, >> >> On Thu, Feb 3, 2011 at 8:02 PM, Corey Kovacs <[email protected]>wrote: >> >>> Excellent, >>> >>> >>> Thanks >>> >>> -C >>> >>> On Thu, Feb 3, 2011 at 10:38 AM, שלום קלמר <[email protected]> wrote: >>> > >>> > >>> > On Thu, Feb 3, 2011 at 12:35 PM, שלום קלמר <[email protected]> wrote: >>> >> >>> >> >>> >> >>> >> https://access.redhat.com/kb/docs/DOC-3068 >>> >> >>> >> On Thu, Feb 3, 2011 at 11:13 AM, Corey Kovacs <[email protected] >>> > >>> >> wrote: >>> >>> >>> >>> Is using ha-lvm with clvmd a new capability?
