Red Hat Bugzilla – Bug 209266
Please add lvm_tab to /etc/init.d/netfs script
Last modified: 2014-03-16 23:02:56 EDT
/etc/init.d/netfs scripts will activate all the VGs in the system by the command
'vgchange -ay'. There is no way to configure VGs not to activate.
I'd like this feature due to a Cluster I have, with two server sharing a disk. I
want don't want the VGs to be activated at the system startup. I prefer the
cluster daemon (Service Guard in my case) to do the activation on one of the nodes.
For that I need a way to have the init scripts read some config file
(/etc/lvm/lvmtab ?) for the list of VGs to activate.
I've tried using the option for this in /etc/lvm/lvm.conf, but that option
disables the use of the VG until the file is edited again.
This is the same command that's in rc.sysinit - I'm not sure there's a
particular simple change that could solve this.
Long term, you'd probably want a storage daemon that listens to storage hotplug
events and then knows what LVs, VGs, etc. to activate, but that's a long ways off.
With the goal of minimizing risk of change for deployed systems, and in response
to customer and partner requirements, Red Hat takes a conservative approach when
evaluating changes for inclusion in maintenance updates for currently deployed
products. There's really not a good way to fix this simply.
