Help creating image from LVM

  • 772

I need to duplicate CentOS hard drive image for multiple stations. The HD has the following layout:

Disk /dev/sdb: 250GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End    Size   Type     File system  Flags
 1      32.3kB  107MB  107MB  primary  ext3         boot
 2      107MB   250GB  250GB  primary               lvm

I saved /dev/sdb1 to file with fsarchiver but for sdb2 I get:

/fsarchiver savefs an2.fsa /dev/sdb2
oper_save.c#1006,filesystem_mount_partition(): can't detect and mount filesystem of partition [/dev/sdb2], cannot continue.
removed an2.fsa

Although fsarchiver probe simple correctly detects sdb2 as LVM2_member. Is fsarchiver correct tool for this job? What's wrong?

I'm on Ubuntu 9.1 with fsarchiver 0.6.8 and lvm tools installed.

Thanks.

  1. a normal tar backup/restore can do the job for you, and if the disk layout is to be the same on all machines, simply use dd (or derived toos, like g4u, clonezilla etc...)
