If you mean this manager it’s a tool to create the initial vfio configuration for the passthrough. You can do it by hand.

You can try one of the phones that are supported by Ubuntu Touch. I don’t know how good it runs but there are several cheap (= old) phones on the list.

It’s still quite a lot. Samsung is the inventor of F2FS and has a market share of 33%.

Wiki says:

Motorola Mobility has used F2FS in their Moto G/E/X and Droid phones since 2012. Google first used F2FS in their Nexus 9 in 2014. However Google’s other products didn’t adopt F2FS until the Pixel 3 when F2FS was updated with inline crypto hardware support.

Huawei has used F2FS since the Huawei P9 in 2016. OnePlus has used F2FS in the OnePlus 3T. ZTE has used F2FS since the ZTE Axon 10 Pro in 2019.

I assume since Google is involved that more and more Android phones will adopt F2FS in the future.

tl;dr

I’m pretty sure default Android runs almost always on F2FS.

Unfortunately it’s not future proof. Max filesystem size is only 16 TB.

ext4 maxes out at a few tb

Max filesystem size is 1 EiB = 1048576 TiB.

More than enough!

It’s more important to backup your /home than /. /home is where you store your crucial files.

RHEL uses XFS as default.

At the end of the day though after all of our storage tests conducted on Clear Linux, EXT4 came out to being just 2% faster than F2FS for this particular Intel Xeon Gold 5218 server paired with a Micron 9300 4TB NVMe solid-state drive source

I’ll suggest XFS.

The OS splits memory into pages and assigns the pages to applications. A page fault usually means one of two things:

• hardware fault
• programming error

You can check your memory with Memtest86. Some LiveCDs come with it. If it’s a programs fault you can only try other software if possible.

According to source the ecc has to ‘kick-in’ about 3700 times per year and dimm module. That’s 10 times per day and dimm.

Depending on how important your server is to you you’ll either need it (in case of important data you absolutely don’t want to lose) or forget about it (just a hobby project, nothing serious).
