Hello,
I need to automate installation of CentOS 7.0 using PXE and kickstart. My server is diskless, I'm installing CentOS on a 25GB LUN on a FC SAN with 4 paths. This LUN is the only one accessible by the server.
Anaconda processes successfully the installation. But on reboot, I get stuck on a prompt after BIOS. I think I have an issue with storage configuration / bootloader configuration...
I can install it using the ISO, with basic configuration. The /root/anaconda-ks.cfg looks like the following (I striped some part, I cannot copy past because I have only console access through a secured VPN :-/ ): firstboot --enable ignoredisk --only-use=mpatha,sdc,sdd,sdb,sda bootloader --location=mbr --boot-drive=mpatha autopart --type=lvm clearpart --all --initlabel --drives=mpatha %packages @base @core %end
My ks.cfg template is identical (I also cannot attach it unfortunately…).
I tried several things like: - put sda as boot-drive for bootloader (according to http://osdir.com/ml/general/2014-09/msg52181.html ), but anaconda fails with error that this drive cannot be found. It asks to choose another disk, mpatha is the only available. - same with dm-0 (as /dev/mapper/mpatha is a symlink to /dev/dm-0) but anaconda also fails - add to bootloader « --append="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap" »
I also found some post on the web saying that in the « ignoredisk » mpatha mustn't be used but disk/by-id/scsi-XXXX (chapter 23.3.2 of RHEL 7 installation guide), but I don’t know how to manage that.
Is someone ever did that kind of PXE installation, with boot on san & LVM, and help me in the kickstart configuration?
Any help would be highly appreciated!
Best regards, Damien
