--Interesting. How does a resource on B know which node failed and --which filesystems the failed node exported?
it is all through resource group and location constraints. for example I have group called home resource in it are lvm-xfs-nfs-ip. which is native on nodeA. now on location constraints I have set nodeB, nodeC and nodeD in line so if nodeA fails resource group home will go on nodeB. if nodeB fails resource group now will go on nodeC. in my original email I have paste both script. > Date: Tue, 5 Jan 2010 11:48:58 +0100 > From: [email protected] > To: [email protected] > Subject: Re: [Linux-HA] nfs config - help needed > > Hi, > > On Mon, Jan 04, 2010 at 06:41:04PM +0000, sachin patel wrote: > > > > nothing was wrong. it is just we added our need in to it. > > We didn't want to fail over nfs server completly. > > Basically we have four NFS head A,B,C,D they all sees all > > disks.
