 Posted: Fri Nov 16, 2012 10:55 am Post subject: Systemd fails to mount partitions |
 |
|
Hello there. Last time I've tried systemd - was version 29. But I had some problems with it, so I decided to stick with openrc. Now I want to give systemd one more try.
So I enabled systemd overlay, emerged systemd-195, also emerged systemd-units form the overlay. Then did
And reemerged all packages with systemd flag enabled.
Then I tried to reboot with systemd as my init, root partition was mounted fine, but every partition except root failed to mount. If I comment out all these partitions from fstab, system boots and I can get to kdm, but I can't login, as my home partition is not mounted. Any advices? |

1) There is no overlay needed to run systemd as init! Probably your overlay is outdated and pulls in bad unit files.
2) Think of Gentoo having two releases:
arch as stable
~arch as a current/unstable release.
Current systemd-195 should be run with current~arch. And as systemd-195 needs udev-195 you have to special configure some linux kernel .config: devtmpfs |

Thanks for your answer!
1) I've removed overlay, and unmerged package which was from that overlay. But that didn't help 
2) I'm using ~arch, so udev is latest version (195). Also it has openrc use flag enabled, could it be confusing for systemd?
My kernel has those options which you are referring about:
| Code: |
nforce@nforce-laptop /usr/src/linux $ grep CONFIG_DEVTMPFS .config
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
|
Also I have taken those logs, maybe they will be useful:
systemctl dump: http://pastebin.com/Cs6mZAyg
journalctl -b: http://pastebin.com/fpNhc1qk |

As you see:
| Code: | emerge -p udev
These are the packages that would be merged, in order:
Calculating dependencies ..... done!
[ebuild R ] sys-fs/udev-195 USE="acl gudev hwdb keymap openrc -doc -introspection (-selinux) -static-libs" |
USE flag openrc doesn't matter. Systemd and openrc are quiet good compangions living in different rooms in the same house.
To your problem:
You could show us your /etc/fstab
But before that, try fsck of your partition reseved for /home when not mounted!
And "systemctl disable" your somehow rotten plymouth ... |

Tried fsck, it said it's clean. Here is my fstab:
| Code: |
nforce@nforce-laptop ~ $ cat /etc/fstab
#

About plymouth: I am not sure how could it got rotten, I have no service files for plymouth, and no plymouth installed either. However, there are some files which could be plymouth's, but I am not sure how they got here:
| Code: | nforce@nforce-laptop ~ $ locate plymouth
/etc/plymouth
/etc/plymouth/plymouthd.conf
/var/lib/lib/plymouth
/var/lib/lib/plymouth/boot-duration

Also, I am not a systemd expert yet, keep in mind:
It is my personal opinion plymouth is a rotten approach, I don't have any plymouth configs. Please look into yours! Might be an automatism of systemd there?
You advise in /etc/fstab your fsck to check two partitions at the same time (1 1)
smoothly diagnose your system:
- make /home in /etc/fstab 1 2 to let check /home after root /
- I would simplify /etc/fstab: comment out what you don't need OR use noauto,defaults as options
- I don't have in fstab: /proc /sys /dev/pts - Isn't this an automatism nowadays?
- Look if the "famous" /usr move is done correctly: /lib/udev symlinks to /usr/lib/udev
- boot with cmdline: nosplash
- boot with cmdline: systemd.unit=multi-user.target OR symlink default.target to multi-user.target - to ignore X at first
- You should use systemd diagnostics: journalctl OR with "systemctl status XYZ" you also get logs shown |

Hmm... I modified fstab like that:
| Code: |
#
# /etc/fstab
# Created by anaconda on Thu Oct 28 22:51:35 2010
#
/dev/sda2 / ext4 defaults 1 1
/dev/sda3 /home ext4 auto,defaults 1 2
/dev/sda5 /mnt/Downloads ext4 auto,defaults 1 3
/dev/sda6 /mnt/Storage ext4 auto,defaults 1 4
/dev/sda8 swap swap auto,defaults 0 0
/dev/sda7 /mnt/WinShare ntfs-3g auto,defaults 0 0
/dev/sda1 /mnt/Windows ntfs-3g auto,defaults 0 0
tmpfs /dev/shm tmpfs auto,defaults 0 0
|
But it didn't help...
About the infamous /usr/ move: no, /lib/udev was not a symlink to /usr/lib/udev. It was a dir containing only virtualbox files, so I removed that dir, symlinked /lib/udev -> /usr/lib/udev, and reemerged virtualbox. However it didn't help too...
Tried to boot with nosplash option - nothing.
And sorry for asking, but how could booting with systemd.unit=multi-user.target help? As far as I can see, it can't get until that target, because it's deps (local-fs) are failing...
It's odd that I can't find anyone with a problem like that, with a google search. It used to be really helpful with other problems of mine  |

What is
1 3
1 4
This is not defined! man fstab:
The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. ...zero is returned and fsck will assume that the filesystem does not need to be checked
Also you could temporarily disable (noauto) all /mnt and ntfs-3g drives, just to diagnose the /home issue at first!
And yes, with your dependency insight! (local-fs) Actually as I said I am not the expert yet ...
---
Additional diagnosis:
systemctl status local-fs.target
systemctl status systemd-remount-fs.service
systemctl status home.mount
dmesg
journalctl |

if you have portage-utils installed
| Code: |
qfile /etc/plymouth/plymouthd.conf
qfile /var/lib/lib/plymouth/boot-duration
|
will tell you what package these were installed by. Same as "equery belongs", but a touch faster.
