Introduction

IT_CF boot a live image from the network to auto register new servers. The image are in aims2 but synced to another PXE boot server for a specific IP Service.

PXE configuration

The configuration live on afs :

/afs/cern.ch/project/linux/adm/aims2menu/hwreg/

To update it modify files on AFS and run:

/afs/cern.ch/project/linux/adm/bin/synchwreg

Everything is copied in :

lxdist:/mnt/data1/tftpboot

Aims2 to hwreg script.

To allow CF to upload their images in aims2 and use them on hwreg, lsyncd synchronise the image between the 2 trees.

vi /mnt/data2/etc/lsyncd.conf
clusvcadm -R aims2sync (lsyncd is part of aims2sync so inotify can detect changes on NFS)

Aims2 add new image.

• Edit:

        vi /mnt/data2/etc/lsyncd.conf
       

• Add the following lines

      sync{
  	default.direct, 
  	source="/mnt/data1/tftpboot/aims2/boot/CF_SLC_65_AUTOINSTALL_TEST", 
  	target="/mnt/data1/tftpboot/hwreg/boot/CF_SLC_65_AUTOINSTALL_TEST"
      }
      

• Restart lsyncd through rgmanager

      clusvcadm -R aims2sync
