[ovirt-users] oVirt and NetApp NFS storage

Hi, I got a question regarding oVirt and the support of NetApp NFS storage. We have a MetroCluster for our virtual machine disks but a HA-Failover of that (active IP gets assigned to another node) seems to produce outages too long for sanlock to handle - that affects all VMs that have

Hi, are you using ovirt storage leases? You'll need them if you want to handle a hypervisor completely unresponsive (including fencing actions) in a HA setting. Those storage leases use sanlock. If you use sanlock a VM gets killed if the lease is not renewable during a very short timeframe

Hi, nope, no storage leases and no fencing at all (because of vlan separation between mgmt and RAC). We have own HA fencing mechanism in place, which will trigger action over API when alarm in monitoring is triggered. HTH On 18.04.19 13:12, klaasdem...@gmail.com wrote: Hi, are you using

I know 2 approaches. 1. Use NFS hard mounting option - it will never give error to sanlock and it will be waiting until NFS is recovered (never tries this one, but in theory might work) 2. Change the default sanlock timeout (last time I tried that - it didn't work) . You might need help from
