Problem:
Install 4.4 to the /dev/sda , everything is ok , after input another clean disk into the server & reboot , the error is can't found /dev/pve/root , pls check the attachments.

(disk1+disk2 = RAID1 /dev/sda, disk4 is the new clean disk )


Solution:
Change /etc/fstab , replace device by UUID, such as :
Code:
root@pro01:~# cat /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
#/dev/pve/root / ext4 errors=remount-ro 0 1
UUID=357ff3f6-6a2e-4cd0-93d9-6968ae82f25d / ext4 errors=remount-ro 0 1
#/dev/pve-4t/4t-data  /data ext4 errors=remount-ro 0 1
UUID=5bce79af-d8e3-4560-88bb-5c163f807ab2 /data ext4 errors=remount-ro 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0

Options, add "rootdelay=30" to the /boot/grub/grub.cfg , such as :
Code:
root@pro01:/boot/grub# grep pve-root grub.cfg
        linux   /boot/vmlinuz-4.4.35-1-pve root=/dev/mapper/pve-root ro  quiet rootdelay=30
                linux   /boot/vmlinuz-4.4.35-1-pve root=/dev/mapper/pve-root ro  quiet rootdelay=30
