-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In doing a backup of a 250GB drive, I was surprised to have a compressed image that was larger than the used space. In the past, I've compressed an 80GB drive with 3 OS's, and get a 14GB image. This is a 250GB drive with only 1 OS, and it is producing an 18GB image. All free space is zeroed out. In doing some research, it appears that about 5% of the LVM partition is being used in some fashion that I am not aware of. The drive shows the volume size as 229GB with 12GB uses, and 206GB Free. That leaves about 11 - 12 GB missing. Whatever is in this 5% of the drive doesn't appear to compress very well with either lzop or gzip. With lzop the image is about 18GB and 16GB with gzip, but lzop only takes about 2 hours, whereas gzip takes about 3 1/2 hours. The image only seems to be runing fine until it gets to the end were this 5% seems to be, and it grows rapidly. Any info on what this 5% is. I'm using g4l, which uses dd to copy the raw partition information, and uses lzop or gzip compression. I was thinking it might be some kind of swap, but why it would be 5% of the disk size, as compared to the amount of ram.
