Recently when trying to open a virtual machine the below error occured:
The solution is a easy to close and re enable HA on the cluster.
Then the VM will be able to power on again.
Sometimes infrastructure servers are physical and directly connected to storage and not virtual ones. In virtualization cases, one has to assign a new virtual disk on the virtual server and proceed with the expand. In case of a physical server one should do the following in order to assign more space on a partition or a lvm.
Find storage adapters and rescan them:
ls /sys/class/scsi_host/
echo "- - -" > /sys/class/scsi_host/hostX/scan
where X is 0 to 10 in my system (some online and some offline)
After re scanning storage adapters a new multipath device will be visible and ready to be used.
multipath -ll
Initialize your disk and use it appropriately.
pvcreate /dev/mapper/mpathm
