write data on diskless ro system

Post by nurweilroot » 2022/03/16 21:06:55

Hello,

i'm trying to build a client-server infrastructure with diskless clients. The clients are starting via PXE and asking the DHCP server for some information like option 67. I'm giving my tftp server with this option and the client is booting from my nfs export. But there are some error messages, because some services cant start because they cant write into my read only file system (nfs export). Is there any way to write this kind of temp data to ram disk and not to the centralised nfs export? Or any other solution? I want to boot more than one clients from this nfs export and i think it is not a good idea for enabling write support. The clients are not all managed by me.

My current default config for this boot via tftp:

default centos8stream

label centos8stream
kernel vmlinuz-4.18.0-365.el8.x86_64
append initrd=initramfs-kernel-version.img root=ipfornfsexportserver:/mnt/nfsexport netboot=nfs ro


Regards & thanks,
