[caasp-beta] read only fs on caasp kubernetes nodes

[Simeon Bobylev]

Hi all,



Is there a specific reason that /dev/sda2 is mounted in read only into / on 
CaaSP Kubernetes nodes ?



c002-caasnode-01:~ # mkdir /var/lib/controller

mkdir: cannot create directory ‘/var/lib/controller’: Read-only file 
system



c002-caasnode-01:~ # head -n 1 /etc/fstab

UUID=abf1dcf2-8539-49d4-8f8e-45c0cf561e80 / btrfs ro 0 0



I would like to test Avi Networks integration with SUSE CaaSP and in order 
to perform that I need to run a container with some volumes mounts, into 
/var/lib/controller for example. Of course I have a new dedicated virtual 
disk for these docker volumes but the problem is even if can add a new disk 
and create partition I’m not able to mount it anywhere because of read only 
mount on /.

I tried to mount /dev/sda2 in rw through “Rescue System” to create needed 
directory /var/lib/controller but I had the same message (Read-only file 
system).



Actually to continue my tests I did something dirty (from my point of view) 
:

c002-caasnode-01:~ # tail -n 1 /etc/fstab

UUID=17153c00-ba92-4bed-9bf6-0a36b43bb176 /var/lib/docker/avi-controller 
ext4 defaults 0 0





What do you think about that ? Is there some best practices for similar 
cases ?
