SUMMARY

When migrating a Live VM in Qemu/KVM from NFS to LinStor , rather than creating a drbd resource on the target system , Cloudstack is creating a Qemu file in /var/log/cloudstack/management/cloudstack directory

If there is not enough space in the device with log directory , live migration fails.

However, if there is enough space , It creates a Qcow file in the /var/log/cloudstack/management/cloudstack/ directory , rather than creating a DRBD device .

Other DRBD volumes are working fine on the host, and host is connected to LinStor controller and has other VMs operating normally , when the VM is created with LinStor as primary storage

[root@host02 ~]# ls -l /var/log/cloudstack/management/cloudstack/ total 20975620 -rw------- 1 root root 21478375424 Oct 3 20:30 46552b99-bd33-471f-897b-7f8de9065725 [root@host02 ~]#

EXPECTED RESULTS

During Live migration + Storage migration, Cloudstack should create a DRBD resource on the target host and move the disk image to LinStore DRBD Device.

To Add. On Management Server , the logs show that LinStor is provisioning the drbd resource
