Hello, I am new to proxmox. I installed the latest version and discovered that very often system cannot boot (init can not find root). Rootdelay=someseconds (I set 20 to be sure) fixes this issue. Is there any default delay value or not?
 
Hello,

Which kernel do you use ? 3.6.32 or 3.10.0-1, available in pve 3.2 ?
You should look at this thread, on kernel 3.10.

Look at the end, the other option you can use, cleaner in my opinion, is 'scsi_mod.scan=sync'. You have to add it in /etc/default/grub, editing the line GRUB_CMDLINE_LINUX_DEFAULT and adding it after quiet.

I had a similar problem, with kernel 3.10, not 2.6.32, and it worked for me.

... and scsi_mod.scan=sync does not work, it seems that it works if adaptec is not charging ZMC module.
 
This problem seems to be quite serious because even rootdelay does not work always. Today a upgraded to the latest 2.6.32-28 kernel and system did not boot for the first time.
