Kernel Update fails ... Oh no, not again!

[george1421]

@sudburr if selinux is enabled, then you will have issues capturing images for sure. You need to configure selinux to permissive. On centos its in /etc/selinux and there is a config file in there you need to edit so it says permissive. Then reboot your FOG server.

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

SELinux is already configured and functions properly for all servers. Imaging is not the problem. The problem is updating the kernel on 2 of 18 physical servers.

@sebastian-roth Following your steps, I get this:

ftp> mkdir /var/www/fog/service/ipxe/backup
550 Create directory operation failed.

It seems that I am able to rename the files though.

I also notice that all of the other files in the ipxe folder are owned by fog:www-data; however, the files the Fog is trying to create for the new kernel are owned by fog:fog. Could this be part of the problem?

One more observation: the fog GUI is reporting that the operation failed to ftp_mkdir and ftp_rename, however the file exists in the ipxe directory and has 8069680 bytes which is probably about right, right? Is the file being copied elsewhere also and failing there? Or, is the GUI error… in error?

@sudburr said in Kernel Update fails ... Oh no, not again!:

Completed the ftp steps detailed and update via GUI continues to fail.

Can you please post a listing or picture of the commands and output?

@jstephen said:

ftp> mkdir /var/www/fog/service/ipxe/backup
550 Create directory operation failed.

This might be due to the fact that the directory already exists. See with ls -al /var/www/fog/service/ipxe on the command line.

[sudburr]

@sebastian-roth Aside from changing your

chmod 644 var/www/fog/service/ipxe/testfile

to

chmod 644 /var/www/fog/service/ipxe/testfile

The commands and results were word for word identical to what you posted.

[Sebastian Roth]

@sudburr Are you behind a proxy server by any chance? Do you still see the very same ftp_* messages in the apache error log?

[sudburr]

@sebastian-roth No proxy server. The error message has changed one one server at /var/log/httpd/error_log.

PHP Warning:  ftp_login(): Login incorrect. in /var/www/html/fog/lib/fog/fogftp.class.php on line 463, referer: http://xyzfog/fog/management/index.php?node=about&sub=kernel&file=aHR0cHM6Ly9mb2dwcm9qZWN0Lm9yZy9rZXJuZWxzL0tlcm5lbC5Ub21FbGxpb3R0LjQuMTMuNC42NA==&arch=64

The value for “Fog Configuration / Fog Settings / TFTP Server / FOG_TFTP_FTP_PASSWORD” changed. It now does not match the password as found in “/opt/fog/.fogsettings” or “Storage Management / Management Password”. I changed it to match, then ran the kernel update again and it worked!

The other server has exhibited no change in errors or passwords.

Kind of weird. Well, good to know it works now. Marking as solved.

[sudburr]

@sebastian-roth It’s solved for one server, but not the other.

Something to look at from the FTP logs.

@sudburr Great log file you posted. See the path is /var/www/html/fogservice/ipxe and I reckon there is a slash missing. Check TFTP_PXE_KERNEL_DIR in the FOG web UI -> FOG Configuration -> FOG Settings -> TFTP Server - should be /var/www/html/fog/service/ipxe/

[sudburr]

@sebastian-roth That did the trick! That server can now update its kernel.

It’s interesting to see how two different causes have similar results.
