DEBIAN-5 HN:

SERVER:~# ls -l /dev/sdb{,1,2,3,4}
brw-rw---- 1 root disk 8, 16 2009-05-07 16:18 /dev/sdb
brw-rw---- 1 root disk 8, 17 2009-05-07 16:18 /dev/sdb1
brw-rw---- 1 root disk 8, 18 2009-05-07 16:18 /dev/sdb2
brw-rw---- 1 root disk 8, 19 2009-05-07 16:18 /dev/sdb3
brw-rw---- 1 root disk 8, 20 2009-05-07 16:18 /dev/sdb4
SERVER:~#
SERVER:~# vzctl set 204 --devices b:8:16:rw --devices b:8:20:rw --save
SERVER:~# vzctl restart 204

You cannot access the hardware from inside the virtual machine.

 

Thank you for your answer.
I found the way to solve this problem. I forgot to write those commands:


SERVER:~#vzctl set 204 --devnodes sda4:rw --save
SERVER:~#vzctl set 204 --devnodes sdb4:rw --save
SERVER:~#vzctl restart 204



Then I started VPS and wrote this command:

root@vps4:~# ls -l /dev/sda4
brw-r----- 1 root root 8, 4 May 8 09:14 /dev/sda4
root@vps4:~# ls -l /dev/sdb4
brw-r----- 1 root root 8, 20 May 8 00:46 /dev/sdb4

root@vps4:~# mount /dev/sda4 /home
root@vps4:~# mount /dev/sdb4 /backup
root@vps4:~#nano /etc/fstab

# UNCONFIGURED FSTAB FOR BASE SYSTEM
/dev/sda4 /home ext3 defaults 0 2
/dev/sdb4 /backup ext3 defaults 0 2

after VPS restarting

SERVER:~#vzctl restart 204

It works OK.

Thank you for your answer to my message anyway.
