Hello.
I followed redhat instruction trying install HA-LVM with clvmd. ( rhcs 5.6 - rgmanager 2.0.52-9 )
I can't make it work.
lvm.conf- locking_type=3
clvmd work
Its failed saying HA-LVM is not configured correctly.
The manual said that we should run "lvchange -a n lvxx" edit the cluster.conf & start the service.
But From lvm.conf :
case $1 in
start)
if ! [[ $(vgs -o attr --noheadings $OCF_RESKEY_vg_name) =~ .....c ]]; then
ha_lvm_proper_setup_check || exit 1
If the vg is not taged as cluster than the ha_lvm is looking for volume_list in lvm.conf.
I am confused- Does the VG should taged as cluster ?? ( BTW - the old fashion HA-LVM is worked with no problems )
redhat instructions :
To set up HA LVM Failover (using the preferred CLVM variant), perform the following steps:
1. Ensure that the parameter locking_type in the global section of /etc/lvm/lvm.conf is set to the value '3', that all the necessary LVM cluster packages are installed, and the necessary daemons are started (like 'clvmd' and the cluster mirror log daemon - if necessary).
2. Create the logical volume and filesystem using standard LVM2 and file system commands. For example:
# pvcreate /dev/sd[cde]1
# vgcreate <volume group name> /dev/sd[cde]1
# lvcreate -L 10G -n <logical volume name> <volume group name>
# mkfs.ext3 /dev/<volume group name>/<logical volume name>
# lvchange -an <volume group name>/<logical volume name>
3. Edit /etc/cluster/cluster.conf to include the newly created logical volume as a resource in one of your services. Alternatively, configuration tools such as Conga or system-config-cluster may be used to create these entries. Below is a sample resource manager section from /etc/cluster/cluster.conf:
<rm> <failoverdomains> <failoverdomain name="FD" ordered="1" restricted="0"> <failoverdomainnode name="neo-01" priority="1"/> <failoverdomainnode name="neo-02" priority="2"/> </failoverdomain> </failoverdomains> <resources> <lvm name="lvm" vg_name="shared_vg" lv_name="ha-lv"/> <fs name="FS" device="/dev/shared_vg/ha-lv" force_fsck="0" force_unmount="1" fsid="64050" fstype="ext3" mountpoint="/mnt" options="" self_fence="0"/> </resources> <service autostart="1" domain="FD" name="serv" recovery="relocate"> <lvm ref="lvm"/> <fs ref="FS"/> </service> </rm>
