[Alexandre DERUMIER]

seem that we can fix it with kernel config:

CONFIG_SCSI_SCAN_ASYNC=n

Yep, it looks as though the same holds for my sas2008i based server too. LVM initialization happens prior to first messages about sda. 

'lvm vgchange -a y' 
brings all the volumes online. 

The fix for scsi users is to change the line in /etc/default/grub: 
GRUB_CMDLINE_LINUX_DEFAULT 
and add "scsi_mod.scan=sync"

Ok, I see /dev/sda .. so it's not related to perc driver ! 

seem to be a lvm problem 

can you try: 

#pvdisplay 
#pvscan

can you do an "ls /dev/" from the hanging initramfs ? 



yes, there is no lvs(pve-root/pve-data/pve-swap) in /dev/mapper
