options 66 (hostname startserver = 192.168.X.X)
options 67 (name of startfile = bootwiz.sys)

Make sure that you restart the Acronis File Server and PXE Server after you modify the options.

This has being tested with Acronis 9 and Windows 2003 Edition.

Hope this helps

1) Creating a snapshot of your current LVM

[root@svr2 ~]# lvcreate -L1000M -s -n volbackup /dev/VolGroup00/datavol
Rounding up size to full physical extent 1.00 GB
Logical volume “volbackup” created

2) You should see lvdisplay stating the snapshot LVM.

[root@svr2 ~]# lvdisplay /dev/VolGroup00/volbackup
— Logical volume —
LV Name /dev/VolGroup00/volbackup
VG Name VolGroup00
LV UUID H1s7bn-TKCu-sdfE-Xi0M-oZNA-ixvq-xsWvZj
LV Write Access read/write
LV snapshot status active destination for /dev/VolGroup00/datavol
LV Status available
# open 0
LV Size 100.00 GB
Current LE 3200
COW-table size 1.00 GB

Allocated to snapshot 0.00%
Snapshot chunk size 4.00 KB
Segments 1
Allocation inherit
Read ahead sectors auto
– currently set to 256
Block device 253:4

3) Create a folder for it to do a proper mount.

[root@svr2 ~]# mkdir /backupvol
[root@svr2 ~]# mount /dev/VolGroup00/volbackup /backupvol

4) Do the backup now.

[root@svr2 ~]# tar -cf /root/datavol.tar.gz /backupvol

5) Umount, remove folder and delete the snapshot LVM

umount /backupvol
rm -rfv /backupvol
lvremove /dev/VolGroup00/volbackup

A small issues just happen today which took me a while to figure how to resolve the issues.

While the vzdump is performing a backup of one of my VPS, i hit with this error

Feb 21 01:33:32 INFO: tar: ./boot: Warning: Cannot savedir: Input/output error

The first impression is that the disk might have issues, but after 5 mins of verifying of the physical disk’s health, I have notice that it is due to the LVM snapshot created during the backup.

The default size that vzdump create for the logical volume is only 500MB, you need to increase to a higher diskspace provided your Volume Group has enough free space.

nano -w /usr/bin/vzdump

Edit 500m to a higher diskspace as needed.

run_command (\*LOG, “$lvcreate –size 500m –snapshot –name vzsnap /dev/$lvmvg/$lvmlv”);

Hope this helps …

So I used this tool called arping.

Let’s said I want to check whether 192.168.1.1 is configure on more than 1 host. You need to test it on another machine which is not configure as 192.168.1.1

[svr1:/root]# arping -I eth0 -c 3 192.168.1.1
ARPING 192.168.1.1 from 192.168.1.99 eth0
Unicast reply from 192.168.1.1 [00:0D:A2:02:3B:53] 1.090ms
Unicast reply from 192.168.1.1 [00:0D:A2:02:3B:53] 0.837ms
Unicast reply from 192.168.1.1 [00:0D:A2:02:3B:53] 1.031ms
Sent 3 probes (1 broadcast(s))
Received 3 response(s)

As you can see, the host that response has the same mac address means this IP address is not conflict with any of the host on the network.

To simplify things, you can use this single command that uses “Duplicate address detection mode (DAD)”.

[svr1:/root]# arping -D -I eth0 -c 3 192.168.1.1 >/dev/null;echo $?
1

If you get “0″, it means that the IP address has conflict with another host

or

it also means that there is no host in the network configured on the IP address.

So I got “1″ on the IP address I am trying to detect, it looks like IP conflict is not a issue here for me.

Hope this helps someone…
