Mounting a disk

Thanks! That would be great :slight_smile:

I use RancherOS 1.4.2 rancheros-vmware.iso successfully mount directory form my nfs server.
RancherOS mount command is build from busybox, not the GNU mount command, so there maybe some different.RancherOS has no mount.nfs & mount.nfs4 which installed by nfs-common by default, so without mount.nfs... user need to add options.

#cloud-config
mounts:
- ["192.168.1.109:/mnt/data", "/mnt/test", "nfs4", "nolock,proto=tcp,addr=192.168.1.109"]

output:

[root@rancheros-nfs docker]# ls /mnt/test
1.txt
23

I tested this on 1.4.2 it worked flawlessly, on 1.5 it does not

24

I also try on 1.5.0-rc1 rancheros.iso, the result is success, maybe needs more testing.

[root@rancher rancher]# ros -v
version v1.5.0-rc1 from os image rancher/os:v1.5.0-rc1

[root@rancher rancher]# ros c export
mounts:
- - 192.168.1.79:/mnt/data
  - /mnt/test
  - nfs4
  - ""

Found this: https://github.com/rancher/os/issues/2606 …makes sense?

Okay, but how do I define a mount using the disk’s uuid?
