Hi,


I made a diskless image against Fedora15, during the boot I found it displayed the following error message and went into emergency mode.



The error message:
Starting Relabel all filesystems, if necessary ^[[1;31maborted^[[0m because a dependency failed.

[ 107.607155] systemd[1]: Job fedora-autorelabel.service/start failed with result 'dependency'.

Starting Mark the need to relabel after reboot ^[[1;31maborted^[[0m because a dependency failed.

[ 107.625156] systemd[1]: Job fedora-autorelabel-mark.service/start failed with result 'dependency'.

[ 107.658580] systemd[1]: Job fsck@tmpfs.service/start failed with result 'dependency'.

[ 107.666876] systemd[1]: Job tmpfs.device/start failed with result 'timeout'.

Welcome to emergency mode. Use "systemctl default" or ^D to activate default mode.




And when I run the command 'service sshd start' to start the sshd, it displayed the following error message:
[ 8545.884404] udev[2872]: starting version 167

[ 8635.560123] systemd[1]: Job tmpfs.device/start timed out.

[ 8635.616355] systemd[1]: Job tmpfs.device/start failed with result 'timeout'.

Welcome to emergency mode. Use "systemctl default" or ^D to activate default mode.


Then I tried to start the tmpfs.device
# systemctl start tmpfs.device
[432039.543362] systemd[1]: Job tmpfs.device/start timed out.

[432039.549335] systemdJob timed out.



Looks like the tmpfs.device was not installed. Did I miss something that depended by system? Any comments are appreciated.




Thanks

Best Regards

Emergency mode systemd target is equivalent to runlevel 1 singleuser
mode at SysV init system, thus probably network isn't active and sshd
refuses to run.

I'm not sure, but tmpfs (shm fs) need active swap, which probably isn't
on diskless station.

Another question is, when SELinux is appropriate to run on diskless
station (you may try disable it).

I also saw problem, when dracut was not able start diskless PXE F14
station when LAN default router was down (but it isn't this case).

Or there is just reciprocal proportion principle: when systemd consumes
10x more RAM then SysV init, then he can 10x fewer.
(narrowly, i686 F15 system comsumes 9x more RAM compared to i686 F7
SysVinit on my systems)

Not 100% sure but take a look at this

http://fedoraproject.org/wiki/Features/var-run-tmpfs

and also try

systemctl enable NetworkManager-wait-online.service

Yes since we do not support labeling on NFS, SELinux most likely will
not work in this environment.

Frantisek,



Thanks for your reply.



I tried to link the /lib/systemd/system/default.target to /lib/systemd/system/graphical.target, but the error same.



And you mentioned the swap, I don't know to enable it, could you give me a hint?



I also found the selinux was not installed on the diskless node. Then entry 'SELINUX=disabled' was configured in the /etc/sysconfig/selinux.



I found a way to workaround the starting of sshd.

I commented out the '. /etc/rc.d/init.d/functions' from the sshd control file: /etc/init.d/sshd. Then sshd was started successfully.



Thanks

Best Regards

Robert,



I don't know what I should do to test the var-run-tmpfs. At least I can touch file in the /var/tmp/.



The service 'NetworkManager-wait-online.service' was not installed on the diskless node. But I found a way to boot the sshd, so I think it was not a network issue.



Thanks

Best Regards
