Ubuntu 18.04 get to read only mode system

[talbaror]

Hello ,
I have XCP-NG platform with Ubuntu 18.04 vm's running along with Windows machines .
its happen that few time we had storage connectivity issue the Ubuntu Linux VMs got into read only mode.
The only way to remove it is by doing fsck to the system ,my question is
Is it possible to make the Ubuntu less sensible for read only mode ?

Thanks

Hi,

Without knowing what kind of SR you are using, it's hard to answer.

NFS

1. You should absolutely start to solve your connectivity issues first. Remember it's like (from the VM perspective) unplugging its live disk. Having a reliable storage network is crucial
2. You could test by adding hard mount option

@talbaror by the way you can find discussion about all this, and what users have tried, etc., at:

open Use NFS hard mount instead of soft mount to avoid RO VMs (or offer option)? #334
