Hi all. This is probably more of a HA list, or possibly even linux-practices, question but all hosts concerned are running CentOS and I reckon some of you guys might have some good suggestions. Feel free to tell me to piss off. :) I'm building a new CentOS, DRBD, Heartbeat and NFS HA cluster. We already have boxes running similar setups on FC2/3 running NFS v2/3 with the Ultra Monkey Heartbeat packages. These new systems are using CentOS packages as much as possible. [root at tempmailstore1a ha.d]# rpm -qa | grep -Ei 'heartbeat|drbd' heartbeat-pils-1.2.3.cvs.20050927-1.centos4 heartbeat-ldirectord-1.2.3.cvs.20050927-1.centos4 heartbeat-stonith-1.2.3.cvs.20050927-1.centos4 heartbeat-1.2.3.cvs.20050927-1.centos4 kernel-module-drbd-2.6.9-22.0.1.ELsmp-0.7.14-1.centos4 drbd-0.7.14-1.centos4 I'm messing around with NFS v4 (any and all experience/horror stories about EL4's NFS v4 in production environments more than welcome as I'm still at the evaluation/test stage) and looking at the best way to setup the --bind mounts for the NFS v4 pseudofilesystem. So far in /etc/ha.d/haresources I have... tempmailstore1a IPaddr::192.168.24.73 \ drbddisk::r0 \ Filesystem::/dev/drbd0::/mnt/drbd::ext3::rw,acl,data=journal \ portmap \ nfslock \ nfs \ rpcidmapd Now, after the Filesystem resource.d script's called ideally I'd like to setup the --bind mounts as detailed here... http://www.citi.umich.edu/projects/nfsv4/linux/using-nfsv4.html As follows... mount --bind /mnt/drbd /export/drbd I would've thought the best way to achieve this, since it's effectively another filesystem of type "none" when mounted would be with the resource.d/Filesystem script... which can't take a --mount option. Obviously I can hack around in the shell script or write my own, has anyone else bumped up against this? And how did you deal with it. Will.
