Partimage-trouble with restore operation.
I currently have a static version of Partimage installed & there seems to be a problem restoring the gzip clone I made with this same static version. It complains that its own compression-level is invalid. This was a single 4.3GB clone file (sda1_img.gz.000) of my root partition. I didn't use the "split" option of Partimage because my kernel supports both LBD (large block device) & LSF (large single file).
After the unsuccessful attempt at restoring the single large clone file, I used the "split" option of Partimage to create a set of gzip clones (sda1-img.gz.000, sda1_img.gz.001 & sda1-img.gz.002). This time the restore operation was successful. Actually I didn't write anything back to my disk because I used the "simulation" mode of Partimage in both instances My current version of Partimage is 0.6.5 (partimage-static-0.6.5-1.rh9.rf.i386) but I ran into this problem with other distribution versions of Partimage too. Those other versions were even worst, they all completed the clone operation successfully but none of them would do a restore. I even tried the partimage-0.6.4-static.tar.bz2 package but couldn't restore any clone either. I think Partimage may be using a version of Gzip that doesn't support (LSF) large single files. I guess that if your clone file is bigger than 2GB you are SOL. Maybe they are using gzip to compress & some other program to de-compress the clones. I would appreciate hearing from anyone who has had this problem with Partimage & especially those of you who know how to solve it. ---Thank you for reading this post. |

There is a way around wrong sized partition issues, just use it's resize features to resize your partition by a couple megabytes so it can resize the partition to fall within the C.H.S. values before making an image of it, then you'll be able to either make a new partition with this utility to restore the image to it, or restore the image in the original "properly sized partition". EDIT: BTW. this utility makes compressed images without un-allocated sectors, meaning, A Linux root partition which uses up 5.5GB of it's partition, the image will be 1.5GB in size. |
