We've had transient datastore failures, and are trying to understand our mitigation options. It's documented / we've observed that if an esxi host loses access to a datastore, virtual machines will continue to run on that host from some amount of time before the virtual machine is told the disks are read-only. This time appears to be on the order of 5 to 15 minutes. If the datastore is restored within some grace period, it resumes operating normally. * What factors affect the grace time before the virtual machine is affected? * Are there any vSphere configuration options which can affect the grace period for specific virtual machines?

Due to failure of a datastore, our Ubuntu/debian based system's root disk went into read-only  -- we have the mount options in /etc/fstab set to errors=mount-ro. I was unable to get mount -o remount,rw / to work and eventually rebooted the virtual machine. Has anyone been able to remount a disk that went read-only?
