PV-TIMEOUT

1. Can any tell me where store the PV-TIMEOUT value of a PV? Is it store in the PVRA in the disk or in the systems /etc/lvmconf/vgxy.conf file?

2. If i change PV-TIMEOUT value in the primary node,then it is necessary to change the same in the 2nd node in a cluster?

Hi,

PVRA stores the structural information like size and identification of the P.V. There are around 19 commands backed up by vgcfgbackup by the LVM subsystem and one of them is pvchange and hence as timeout is configured with pvchange -t, it would maintain that info in the file /etc/lvmconf/vgname.conf.

Thanks for replying Ismail.

So if we change PV-TIMEOUT in primary node then we have to change the same in 2nd node also in cluster.

Hi,

Since on SG , cluster architecture is normally of the shared disk type, I would say yup!.

Welcome to ITRC! Don't forget to assign points.

On SG environment, certain changes made in LVM, needs to be aware by all nodes within the cluster.
