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
Hello,
Please forget, I found the issue. In fact I put a wrong url in ks (url --url ...), so it wasn't able to DL the package.
But the time it waits before timeouting and the fact its reboots (in text mode) without any error message is quite hard to tshoot...
Thanks!
Damien
