I have a spare My Cloud PR4100 that’s kept as a backup for my file server, so I decided to upgrade from My Clouud OS3 to My Cloud OS5, strictly for experimentation. Eventually, I plan to transfer OS5 to a bootable USB stick so I can experiment more easily by making direct changes to the filesystem and observing the results.
My first impression is that it’s the same old dashboard as before, with some minor changes. It also tries very hard to connect to the internet, and it really wants you to allow it to share “Analytics”, where the “Analytics opt-in” notice doesn’t look too bad at first glance, but reading the actual “EULA” and/or “Terms of Service” made a chill go down my spine. No thanks, it’s blocked from accessing the internet, and I have no plans to change that.
The first order of business is to make a backup of the eMMC just in case something goes wrong, and save a copy of the kernel boot log for analysis.
dd if=/dev/mmcblk0 of=/shares/Public/mmcblk0_OS5.07.118.img bs=512
dmesg > /shares/Public/dmesg_OS5.07.118.txt
My Cloud OS5 appears to be going through some teething pains, so I plan to wait until it stabilizes before diving too deeply into it. OS5 finally has a somewhat recent Linux kernel, which opens up many possibilities, where I believe it may be possible to strip out most of the unwanted parts, thus making it into something more suitable for a simple home NAS server.
