SCADAPack 474i read only filesystem

[seacunab]

Hello

I have a SCADAPack 474i but I can not create any file because the linux filesystem is read only mode.

How to change to read-write mode?

Best regards

I suspect that the SCADAPack design imposes this read-only aspect.

To get around this, you likely have to redploy your own custom Yocto image based on the Schneider standard image.

https://docs.yoctoproject.org/next/dev-manual/read-only-rootfs.html

I believe there are only certain mount points which are on read-write file systems.
From the docker example https://www.youtube.com/watch?v=GMnwrUbNRxU, it looks like /home/root/... is on a write-able file system.  And it suggests that /etc is also (to allow for resolve.conf to be updated... although it's possible this is just a RAM disk, and is reset on each power cycle).

Hello @BevanWeiss 

This issue is affecting create docker container in the home directory

But, based on your suggest, I can create into /etc folder, but is not the ideal. I would like create into /home folder.

For now, I continue with this workaround

Thank you

Hi, if you check the following document

"SCADAPack 47xi Application Note - Docker App Connectivity and Redis Overview"

at page 14 you can read:

"The SCADAPack 47xi filesystem image is read-only but can accept a read/write filesystem overlay
that resides on the Edge platform’s SD Card. Installing the overlay causes the read-only filesystem to
become read-write. To make any changes to files on your Edge platform, you need to have a
filesystem overlay installed."

hope that helps
