Recently built a new computer, didn't want to deal with the headaches of distros like Gentoo like I did at work back in the mid 2000's, so I went with Mint. Had to manually install mdadm in the live CD environment, used mdadm to create RAID1 mirror for /var, /tmp and /home on a magnetic drive so I didn't wear out my NVMe drive with heavy writing (SWAP, /var, /tmp and /home are the parts of the linux filesystem that receive the most write traffic - learned this back in the day).
Anyway, the installer couldn't understand that since I used mdadm to create the RAID array, that the volume blk_id for the three RAID devices should be written to /etc/fstab for their appropriate mount points before the first boot of the system - and instead used the partitions on the first disk. Wonderful. So let's create a RAID then. Nope. Get fucked, user.
Had to end up installing with SWAP on the first two partitions of both magnetic drives (have 64GB of SWAP, lol) and /var, /tmp and /home on the NVMe drive, rebooted, and manually moved over /var, /tmp and /home to the first magnetic drive, used mdadm to create the RAID mirror, manually added blk_id of the mdX devices to /etc/fstab mount points, and rebooted. Worked perfectly after that.
Hey distro mods - INCLUDE mdadm on your install disk and take into account if someone fucking creates a mirror during install instead of having people manually do this on the first boot - fucking their shit.
THIS, along with other issues, is what stops linux from dominating the normiesphere.
along with other issues
Built a new computer fully expecting to have a linux main boot on a raid-0 array with a small ssd for a windows boot. Too bad the MB uses a certain chipset that doesn't support linux. I never did figure out how to fix it, even 6mo later looking for a fix.
So I just went with windows with a linux backup on a separate drive.
My MB has a UEFI hardware RAID option and a Legacy hardware RAID option. Linux wouldn't recognize the UEFI RAID. Find out after a day of researching that UEFI RAIDs only work on Windows. So, let's go the legacy route then. Follow MB instruction manual - turn on compatibility mode in BIOS (which disables UEFI) and hit Ctrl + R on POST screen when prompted. Ok let's do this. NOPE. Never fucking prompted, so I cannot set up a legacy RAID at all. Had to fucking go with a software RAID using mdadm. Absolute shit-tier - the hardware RAID would have just made the two partitions look like one, simplifying use... and I wouldn't have had to deal with the issues I had. I even updated the BIOS and no-go with legacy RAID.
New tech seems to be coming out too quick for bugs to be worked out, or we're having severe diversity-hire issues in these companies.
Yeah, it was some issue with AMD out-sourcing their chipset's software and the software maker just.... Didn't support linux.
