Hi Friends !!!
I have one xen server (debian etch) already in production; there are
samba, squid, 2 ldap servers , apache2, postgresql and others, 8 virtual
machines at total in a hardware raid5. Now I need a backup system, and i will
use bacula with a dell ultrium3 LTO.
I would like to know if there are problems with i/o? How can I connect
a DomU directly to /dev/st0 of Dom0 ?? Its a very good machine ( 4xXeon 4GB
Ram ) , but i'm afraid to run bacula-fd in all DomUs and bacula-dir and
bacula-sd in a DomU too, and get I/O problems, or may crash xen , corrupt
data... whatever....
Use pciback.hide in grub.conf for you SCSI card attached to your tape
drive.
itle CentOS (2.6.18-8.1.4.el5xen)
root (hd0,0)
kernel /xen.gz-2.6.18-8.1.4.el5
module /vmlinuz-2.6.18-8.1.4.el5xen ro root=LABEL=/
pciback.hide=(02:0b.0)
module /initrd-2.6.18-8.1.4.el5xen.img
And then allow access to the PCI card in your domU configuration.
kernel = "domU-current"
memory = 256
name = "backup01"
vif = ['ip=192.168.1.2]
pci = [ '0000:02:0b.0' ]
dhcp = "dhcp"
disk = ['phy:/dev/vg/disk01,sda1,w', 'phy:/dev/vg/disk01.swap,sda2,w']
root = "/dev/sda1 ro"
