Proxmox 4 Installation Issue on LSI Raid Systems Rumi, March 4, 2016 I was installing Proxmox 4.X on my new server systems having SAS disk with LSI MPT2 Raid controller. The installation went just perfect, however, after post installation boot- I was getting errors as below similar screenshot- After googling a lot, found the solution. Here goes it- On the initial boot screen- select “*Advanced…..” Hit “e” on the next screen You’ll find something similar as below- title Debian GNU/Linux, kernel 2.6.26-1-686 root (hd0,0) kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/sda1 ro quiet initrd /boot/initrd.img-2.6.26-1-686 add rootdelay=90 after quiet Hit “Ctrl+X” or F10. The boot will initiate and you;ll have the login prompt appears on screen. Success!!! Now, let’s make it permanent for the next boot. now open /etc/default/grub and add the following command- GRUB_CMDLINE_LINUX_DEFAULT="quiet rootdelay=90" Save it Now issue the command- update-grub Now time to reboot Problem resolved!!!
