Re: [xcat-user] [External] Netboot process stuck

Song BJ Yang Fri, 15 Mar 2019 03:37:00 -0700

Hi,

If the console output covers the whole process, seems the the initrd boot up process did not reach the rootimg download phase. And there is a `[2019-03-14T10:20:39-03:00] [ 37.280041] systemd-fstab-generator[261]: Could not find a root= entry on the kernel command line.`,

several questions:

1. what is the node status: `lsdef <node> -i status,statustime`? is it changed to "netbooting"?

2. did you provision a batch of nodes with the same osimage? did the issue always appear on the same node?

3. please install xCAT-probe on you MN, run `xcatprobe xcatmn` to check if any configuration issue.

and watch `xcatprobe osdeploy -n <failing node>` in 1 terminal session, and then kick off provision. You will find the provision progress in the xcatprobe session. Please provide that session output.

Thanks Song,

I added the following kernel parameters:

debug ignore_loglevel log_buf_len=10M print_fatal_signals=1

The console output file is attached. I noticed that the machine's devices were not found in the udev database.

Hi,

We encountered a similar issue https://github.com/xcat2/xcat-core/issues/274 , but in this case the console uncovered the root cause.

However, your console output does not show why the boot up process hang. I suggest you add more verbose output during boot up, this is a reference dochttps://www.askapache.com/linux/linux-debugging/ on how to get more debug info during kernel boot up.

To apply the kernel options during diskless kernel boot up, you can leverage the `addkcmdline` attribute, an example for addkcmdline usage ,

chdef mid05tor12cn05 addkcmdline="debug ignore_loglevel log_buf_len=10M print_fatal_signals=1 LOGLEVEL=8 earlyprintk=vga,keep sched_debug"

good luck

What does the boot kernel get command line wise (e.g. /tftpboot/xcat/xnba/nodes/<nodename>)

Notice that the boot process is slow.

The machine has the following configuration:

2x Intel Xeon E5-2670

256GB RAM

Motherboard Supermicro X9DRG-HF

HDD 1TB

Mellanox Infiniband ConnectX-3 card (MT27500)

GPGPU nVidia Tesla M2075

I removed all off-board cards and HDD. The boot process stays stuck in the same stage. I installed CentOS 7 minimal ISO on HDD and the problem did not occur.
