In order to configure Acronis SnapDeploy with Microsoft DHCP, you need to modify two options so that when DHCP issue the IP address, the client know who to contact for the PXE Boot Images.

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

Performing backup of your logical volume is pretty easy and fast. It is the safest way to backup any “open” files/databases.

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
COW-table LE 32
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

I am using vzdump tool which make use of LVM to do snapshot of the VPS which ensure that there is data consistency during the backup as the VPS is online while the backup is performed.

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 …

I was upgrading GD on one of my DirectAdmin box and I got into this error. Seems like one of the compilation program version is outdated therefore I have to update them manually.

wget ftp://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
tar zfx m4-1.4.9.tar.gz
cd m4-1.4.9
./configure –prefix=/usr
make
make install

At the same time, I will upgrade autoconf as well

cd /usr/src
wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.61.tar.gz
tar xzf autoconf-2.61.tar.gz
cd autoconf-2.61
./configure –prefix=/usr
make
make install

Hope this help someone out there and as a reference for me in future
