Hi Chao,

On my F21 laptop I tried to start kdump service "systemctl start kdump" and it failed. I tried to figure out what's wrong and did "systemctl status kdump" but I don't see any messages there.

[vgoyal@localhost ~]$ systemctl status kdump.service ● kdump.service - Crash recovery kernel arming Loaded: loaded (/usr/lib/systemd/system/kdump.service; disabled) Active: failed (Result: exit-code) since Wed 2014-11-19 11:49:43 EST; 4s ago Process: 31725 ExecStart=/usr/bin/kdumpctl start (code=exited, status=1/FAILURE) Main PID: 31725 (code=exited, status=1/FAILURE)

Actually it works for me:

When I ran "kdumpctl start" manually, It showed that no memory is reserved.

I think this message should go to journal so that systemd can show it. I am wondering what's the problem here.

What does your /etc/systemd/journald.conf look like? What does "journalctl -b -u kdump" give you? What about other services? Do their logs get lost too?

Thanks WANG Chao
