Hey there,

Could you describe the steps for expanding the LUN? From expanding on IBM to resizing the disk on oVirt.
I don't work with IBM, but I believe it is similar to HP, Infortrend, Dell... Is your IBM Storage FCP or iSCSI?

Can you identify if the LUN has been expanded on the host, using the multipath -ll command?

Hi,
We have multible oVirt clusters (based on CentOS 9 Stream) with several nodes (based on the 4.5 el9 node image) in each and a great number of virtual machines (mainly RHEL 8).
The problem we encounter is random, it happens sometimes and other times not.
Backend storage consists of SAN attached IBM Storwize V7000.
Problem is when we expand a LUN on the storage system and wishes to expand it in oVirt for use in the VM, sometimes this process hangs the VM completely, it shows as running in oVirt GUI, it cannot be paused/shutdown from the GUI - only way to shut it down is to login to the node running the VM and from virsh run a destroy command.
Anyone else encountered this problem?
/John
