This has caused quite a stir among the Acronis True Image users who happen to dual boot Windows and Linux and like to use their product to create system backups of both their operating systems.
The solution to the problem is very simple.
First, we need to check what our filesystem currently uses. This is done using the tune2fssystem utility.
The above command polls the filesystems on the relevant /dev/ device for information. The grep command merely extracts the specific bit we need.
Let's see what we get on our Ext3 filesystem formatted by GParted (our sdb5 from earlier):
We have the Inode size: 256. Not good. We won't be able to use Acronis. So we need to change the size. This can be done using the mke2fs formatting utility for Ext2-based filesystems.
This will format the sd5 device as Ext3 filesystem (-j flag) with Inode size 128 (-I flag).
Indeed, if we check again:
Our Inode size is good now. In general, I recommend all dual-boot users, especially those fond of imaging, to perform these steps manually on all partitions they intend to use for Linux and image from Windows and/or using a Windows-based program like Acronis.
That's about it.
We now know the ins and outs of partitioning and working with GParted. Congratulations!
Now, for some extras ...
