Issue still persisted after rebooting and running fsck. Host went into read-only mode not long after it came up.

XCP-NG Host stuck in read-only mode
Recently experienced an issue of host upgraded from XenServer 6.5 to XCP-ng going into read-only mode. Once in this state, VMs can't be migrated to other hosts nor can VMs be started on the host. When restarted the issue is resolved for a short time but then re-occurs.
Did a fsck check and repair but this did not resolve the issue. Posts on similar issue pointed to a boot disk failure and so we replaced the disk and re-installed XCP-ng Ver 8.0 but once added back to the pool the issue re-occurred. Trying to start a VM on the host shows the error below:
Does anyone have any experience with this and how to resolve.
