This is a really strange problem, and is intermittent, so I’m finding it had to work out what’s going on. Firstly, the issue is not specifically to do with Antergos. It happens with Manjaro too, and I suspect will happen under all Linux systems.
I currently have two hard drives – a 3 TB drive I use for storage, and a 2TB drive I use for Windows 8.1, Antergos and storage. The issue is, sometimes Antergos fails on bootup, and it happens exclusively when I’ve just booted into Windows. What happens is that my external drive partitions fail to mount. and I get a string of messages along the lines of…
[FAILED] failed to mount /media/audiobooks
See "systemctl status media-audiomount for details
[9.385045] system: failed to mount /media/audiobooks
This is just a small example of what goes wrong. Every partition on my secondary drive fails to mount, and I’m no sure how to get more information. ‘systemctl -xb’ works from the command line post-failure when I’m stuck at the command prompt – the X Server always fails to start – but I’m not sure how to dump all that information into a text file in order to save it and post it here.
All I have to do to fix the issue is to boot Windows 8.1 as far as the log-in screen, restart, and Antergos loads perfectly and will do again until I use Windows again.
Now, I rarely use Windows. I didn’t use it for three months recently and the problem never occurred. This past week I’ve had to use Windows every day, and the problem’s happened a few times. It doesn’t happen every time, and I’m tempted to say that the problem is somehow to do with Windows Updates. The issue seems to occur either before I install Windows Updates or immediately after. It doesn’t happen every time I use Windows, but every time it does happen I’ve either just installed some Windows updates, or Windows is informing me that I need to install some updates. Might be a wild coincidence… might not.
Again, to stop the problem, all I have to do is boot Windows as far as log-in, restart, boot into Antergos and the problem’s fixed.
Can anyone advise me what might be the issue here, or give me a few ideas on how to view the logs of a previous bootup failure, or progress with the issue? I’m not sure whether it’s relevant, but I have a non-UEFI motherboard, all the drives were formatted using msdos (as opposed to GPT), but all partitions are much smaller than 2 TB in size.
