Hi again list
I've posted some questions about the bacula cd rescue, but I've managed
to make it work (or some kind of).
Here is what I did.
I've installed bacula director in a Debian lenny box, using apt, and
some clients using different ways (yum, rpm from sourceforge, apt).
As it is just a test of a bare metal restore, I take it easy and get
some time to investigate and read.
The example I want to restore, is a CentOS 5.2, and bacula-fd was
installed using yum (version 2.4.2).
To make the cd rescue, I've followed the manual instructions, making
first a static bacula-fd, and then using the rescue with it.
The first challenge I had, is that the machine that I'm trying to
restore is a 64 bit CPU, so I had to copy /lib64 and /usr/lib64 to the
roottree to make it work (yes, I copy all..I'll try to copy just
necessary later).
Once the cd worked, I noticed that both using "linux 1" or "linux 2"
gives me a shell, never asking for login, but suppose that there is no
big deal with that (as far as you don't complain about security).
The second problem I faced, was when trying to make partitions with the
script included, and find that there wasn't a /dev/sda when boot. So I
had to follow these steps:
# mount -t tmpfs udev /dev
# udevd --daemon
# udevtrigger
The rest can be mounted too:
# mount -t devpts devpts /dev/pts (need to create /dev/pts first)
# mount -t tmpfs tmpfs /dev/shm
It also made my ethernet card appear.
Once there, I could run the partition and format script.
Then mounted the file system (the scripts mounts it on /mnt/disk), but
as lack of files (bash, libs, etc), the chroot didn't worked out.
To make bacula-fd run, I had to create the directory "bacula"
at /var/lib/.
The next step was te restore, but here comes the problem. It starts the
restore, but a minute or so later, the client gets out of memory and
kernel start killing process (bacula first, and probably bash later).
I tried making swap first, just in case:
# swapon /dev/sda1
but looks like it never uses it.
Deleting extra libs at /lib64 and /usr/lib64 is a shoot, but I'm afraid
that it will keep consuming memory until a new "out of memory" and kill
everything again..
So..any suggestion? any idea? Can I make bacula-fd flush the memory
earlier, before it gets out of memory? or make it use swap?
Thanks to all
Cheers
Martín
