IFL insists on backing up unused sectors in GPT partition.

Postby jeffw_00 » Sat Dec 16, 2017 7:09 pm

Hi - I have a new i7 32GB PC onto which I installed Centos 7.3 from their ISO media. The df -l command tells me the main partition has about 64GB on it. I added a 2nd SATA disk. I downloaded the latest IFL release and ran Makedisk on a Windows PC to make a 3.15 IFL CD. I loaded the CD into the CentOS machine, booted into IFL, and tried to do a full backup from the main disk to the 2nd (empty 160GB) disk. I used Boot-IT Bare Metal to see there were 3 partitions on the main disk.

a 200MiB EFI partition
a 1024 MiB "Linux Native" partition
and the main 19065504 MiB "GPT" partition.

I tried a backup of the whole disk, and of just the partitions, but either way, for the GPT, partition, it wants to backup the -entire- partition, even though only ~144GB is in use. I am not Backing up Unused Sectors, and I am Omitting Pagefile, etc.

how do I get it to ignore unused sectors in the GPT partition?

Thanks!

needs to be a supported file system (ext 2,3,4/resierfs/xfs/fat/fat32/ntfs)

Thanks for the response, especially on a weekend. But are you saying I'm SOL w.r.t. IFL? That's a bummer!

FWIW: I didn't choose the file system. I downloaded the CentOS (Open Source RedHat) install ISO, burned it to a DVD, and installed to a PC with an unformatted disk. So - Is it possible you will support this file system in the future? As it's possible you will hear this from more potential customers (CentOS is not unpopular :-)).

Thanks!

what file system are you using?

you can typically choose it during installation.

Also of course for LVM's, see the lvm.txt document in the help folder (when
you unzip).

Hi - I don't remember getting a choice to be honest (or if I did I let it use the default - thinking it would be the best for the O/S). So again, I expect others may run into this down the road. Although from what I'm reading, people seem to suggest that if the disk dies you should reinstall the latest O/S, which suggests that a gzip file backup will be sufficient... If I make sure I capture my yum log and the /etc folder I should be able to put everything back together.

Anyway -. It was just that IFW et. al., has been so awesome for me over the years I just -assumed- it did everything :-)

best
