File /home/lpar2rrd/lpar2rrd/etc/web_config/hosts.json cannot be written by webserver

sgariboldi · January 30

Hello, this is my first LPAR2RRD installation on CentOS 10 installed on an LPAR of a IBM Power 10 server.

I followed the documentation to install and configure LPAR2RRD on my CentOS and I'm having the following problem. When I open the web page and try to add an HMC, I get the following error:

Host configuration save - fail

File /home/lpar2rrd/lpar2rrd/etc/web_config/hosts.json cannot be written by webserver, check apache user permissions: Read-only file system

On Linux I have disabled SELinux:

[root@CentOS-lpar2rrd]# getenforce

Disabled

[root@CentOS-lpar2rrd]#

Has anyone had the same problem as me and can help me solve it?

Thanks, Sergio.

this is the issue, you see it: permissions: Read-only file system

This output:

mount -a

BTW, you might already hear we have a new monitoring tool called XorMon. It's the replacement for LPAR2RRD and STOR2RRD.

You can find more information here: https://xormon.com/documentation-ng.php .

I recommend testing it out at least, it's a much better tool. It has many new features compared to our older tools.

LPAR2RRD neither STOR2RRD not being further developed, just bug fixes and small enhancements.

Thanks Pavel,

I have already verified that all filesystems are in rw and that in the directory /home/lpar2rrd and its children the user lpar2rrd and the user apache can read, write and execute commands.

I'll take a look to XORMON tool.

su apache -s /bin/sh -c "ls -l /home/lpar2rrd/lpar2rrd/etc/web_config/hosts.json"

this command will give yuo OS view on access to file as user apache.

is this working?

su apache -s /bin/sh -c "touch /home/lpar2rrd/lpar2rrd/etc/web_config/x"

That directory must be writable for apache user
