Kernel panic

Postby damithuk33 » 2017/11/17 10:51:27

I have upgraded to centos 6.x to centos 7.x using mentioned tutorial "http://gree2.github.io/linux/2017/01/10/upgrade-centos-6-to-7". All steps are successfully done, but after reboot server it'll give a kernel panic.

dracut: Switching root
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init Not tainted 2.6.32-431.5.1.el6.x86_64 #1
Call Trace:
[<ffffffff81527513>] ? panic+0xa7/0x16f
[<ffffffff81077622>] ? do_exit+0x862/0x870
[<ffffffff81077688>] ? do_group_exit+0x58/0d0
[<ffffffff81077717>] ? sys_exit_group+0x17/0x20
[<ffffffff8100b072>] ? system_call_fastpath+0x16/0x1b

Please give me an advised to resolve this issue.

There is no upgrade path from 6 to 7.

I'd suggest reinstalling and restoring your latest backup and then doing a parallel install and migrating your services over to the new machine.

https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool <- Note the big fat warning about it being BROKEN at the top.
CentOS 5 died in March 2017 - migrate NOW!
