No more processes left in this runlevel

[Chapaya]

I have a problem :

"Enter runlevel: 3
INIT:No more processes left in this runlevel "

Also , i i can take linux to single user ?

bye.

[Vitaly Karasik_1 · Accepted solution]

Eran, for taking linux into single user level, just add

single

at the end of grub kernel line.

[skt_skt]

1. Intervene at the boot prompt by selecting the required kernel version and hit e; select the kernel line and add single to the end; then hit b to boot

2. Edit grub file before rebooting.
kernel /vmlinuz-2.4.21-40.ELsmp ro root=/dev/vg00/lvol1 hda=ide-scsi usb-handoff single.

system in single user but i still get :

INIT: no more processes left in this runlevel

but do you have shell prompt?

if no, I suggest to boot from some rescue CD (1st install CD, for example), mount and examine your system.

is it fresh installation? or you got this problem after upgrade?

i have ptompt but there are missing files under /etc .
There were some electricity problems ...
also fsck did not fix it .

[Vitaly Karasik_1]

I see a few ways to fix this:
1) restore /etc from backup

2) copy /etc from another linux box and fix appropriate files (/etc/hosts, /etc/sysconfig/network, /etc/sysconfig/network-scripts/ifcfg-* and so on)
But probably you lost some files into other directories too...

3) reinstall

If your distribution is RPM-based, you can detect missed files by running

rpm -qaV

(after booting from a rescue disk)

[skt_skt]

Go to rescue mode using the RHEL installation CD with the boot option:

linux rescue

if vg00 not getting mounted automaically.

2.Try to activate the volume groups by running the commands below:

lvmdiskscan
vgchange -ay

3.If vg00 is acitaved Further fsck test can be done using:

tune2fs -l /dev/vg00/lv01 | grep Block

Take note of the Block size.

e2fsck -b -n /dev/vg00/lv01


Also if you encounter any super block corruption then try
# mke2fs -n /dev/vgeb_gdh0_p/lvol10

i dont have lvm on this machine .

i will go to scrath installation . there are too many lost files on /etc which i see . may be on other fs also .

i seems electricity problems caused it .
