cant mount home on boot

Im giving a go fedora silverblue on a new laptop but Im unable to boot (and since im a linux noob the first thing i tried was installing it fresh again but that didnt resolve it).

its a single drive partitioned to ext4 and encrypted with luks (its basically the default config from the fedora installation)

any ideas for things to try?

The error says /home is a symlink, what if you ls -l /home?

Since this is an atomic distro, /home might be a symlink to /var/home.

So shouldn't you mount your home partition on /var/home instead?

the command returns my user dir and a lost+found dir

There well may be hardware issues, but with ext4 it rarely corrupts the entire file system. You might end up with some data not flushed so you'll have some inodes that don't point to anything that you'll remove with fsck upon boot, but btrfs, I've had it corrupt and lose the entire file system. I've used ext2-through-ext4 for as long as they've existed and never lost a file system though back in the ext2 days I had to hand repair them a few times, but ext2 was sufficiently simple that that was not difficult, but within two weeks of turning up a btrfs file system it shit itself in ways I could not recover anything, the entire file system was lost. If I did not have backups, which of course I always do, I would have been completely fuxored. It is my opinion that btrfs and xfs, both of which have advantages, are also both not sufficiently stable for production use.

rm /home
mkdir /home
make /var/home a symlink to it.
Alternative, edit your /etc/fstab to mount on /var/home.

Don't you have that backwards? This is an atomic distro, and you'd want to mkdir /var/home then symlink /home from that, no? Otherwise, you'll wind up with a home directory that is immutable.

@Telorand I am not familiar with that distro, I am however familiar with how mount works. As far as what is immutable and what is not, you can set with chattr +i file/directory or chattr -i file/directory.

editing the /etc/fstab didnt work (I just changed the path but not sure if the uuid plays any part) but ill give the rm/mkdir part a go

No but I rebooted the system after the change. do still need to update it regardless the reboot?

Edit: Probably try @[email protected]'s solution of systemctl daemon-reload first.

Yes. When booting, your system has an initial image that it boots off of before mounting file systems. You have to make sure the image reflects the updated fstab.

2

You might be right. I was thinking of it in terms of a traditional distro, as I use vanilla Debian where my advice would apply and yours probably wouldn't.

From what I do know, though, I guess /etc would be part of the writable roots overlaid onto the immutable image, so it would make sense if the immutable image was sort of the initramfs and was read when root was mounted or something. Your command is probably the correct one for immutable systems.

@data1701d It will work fine with Debian Bookworm, not sure about older releases, I don't know at what point they switched to systemd controlling that but definitely does work in Bookworm. It should work in most other modern Debian or Ubuntu derived systems as well, but not older versions as systemd taking over this functionality is relatively recent.

Make sure the uuid matches the uuid of the home partition you want, you can list uuids with blkid I think, big noob here too I just spent my last week trying to figure out why it wouldnt mount my boot partition and the problem was the UUID...

@possiblylinux127 @evasync I can't speak for them, but I've had btrfs blow up in ways I could not fix. I didn't just lose a file but the entire file system. I have NEVER had this happen in many years with ext4.

lemmy.zip

Was that in the last 5 years? If it was btrfs is now far more stable. It has never blown up for me and it has in fact saved my data a few times.

I've only had this happen once and it turned out it was because my ram was shitting out errors that were saved to disk so it ended up not being btrfs's fault

NixOS and ext4 user here with no problems. Care to elaborate?

Seems like this can be prevented from reaching that point by properly deleting old generations regularly though right?

2

20 or 30 generations 😹

I have space for 1 😭

Edit: you've got me worried now, is the behavior you're referring to normal running out of inodes behavior or some sort of bug? Is this specific to ext4 or does it also affect btrfs nix stores?

I've run across the information that ext4 can be created with extra inodes but cannot add inodes to an existing filesystem.

Lol same thing happened to me about 6 months ago. Overheating and/or a failing M2 and system corruption. btrfs got weird and troubleshooting only made it worse.

Did you reformat the disk before installing? I've seen similar fails when the disk is still encrypted. The installer can't get a hold of a previously encrypted disk. If there's no valuable data in the disk, load up a live distro run gparted and nuke the disk blank and pristine again, as gparted doesn't care about encryption. Then try the installer again.

2

@dustyData @evasync When I install, I generally prepare the partitions ahead of time with gparted, whether or not I create an entirely new partition table depends upon whether it is the only OS on the disk or there are multiple. I'm not using any encrypted file systems, I need the machines to be able to boot without my being present to type in a password or pass phrase. So that is not an issue.

no, I just removed them with the live cd and repartitioned it (Im assuming its doing the same thing under the hood?)

You should let the installer do the partitioning. Silverblue and immutable systems are nitpicky about it. Specially if luks is involved. The whole point is that you shouldn't meddle with the system at a low level at all.

Sorry, I was not replying to you (not an insult). I assume you are interacting from Mastodon from the format of the comment, and getting pinged on replies to other comments (?). I mean, you do you, absolutely not going to diss people who want absolute control over their system. But immutable distros are fundamentally an entirely philosophically different approach from how traditional Linux distros have been packaged and managed in the past. That said, I didn't make the installers, I'm just reporting what has been my recent experience toying with immutable distros. The whole point is to automate as much as possible of the deployment and management of an OS, and do the least amount of tedious manual troubleshooting. If you don't like that, all the other distros are still there, they haven't gone anywhere. The current recommendation for Fedora Atomic based distros is to use specialized tools like Universal Blue that allows the user absolute freedom to deterministically configure a Fedora install that results in an immutable OS. And the installer is actually pretty flexible to let you choose how you want the disks laid out. But, the idea is that you should let the installer do its job, that's for what it was made. If you want to do everything by hand just use Arch, that's what Arch is for.
