Hello Folks, I have a very interesting issue which occurs very frequently, I have CloudStack version 4.7 with XenServer 7.0 clusters. We are using NFS for primary storage, we have been observing that file system of virtual router goes to Read-Only mode very frequently. However other VMs running on the same SR doest have such issues but it happened specific for VR’s.
I understand that Read-Only filesystem indicates that the filesystem is either not able to access to backend disk somehow or it looses the connectivity from backend SR but if my backend SR has issues then other VMs running on the same SR should also get affected. Has anyone came across with this issue ? So every-time i need to reboot the VR in order to fix the file system which obviously leads some downtime. Regards Vivek Kumar
