http://askubuntu.com – I'm working on a really really wierd project. I'm using Ubuntu to recover an Android device. I'm doing this by launching Ubuntu and then using the GUI to keep the user informed. I need to figure out a way to realign the partition tables. When using parted -l print, parted shows that there are problems on the disk and asks for user input to correct the partition table endings. Is there another tool that I can use for a scripted recovery? Basically, The partition tables at this point are correct, but the disk is in an unknown state. I need to figure out a way to rewrite the partition t (HowTos)

First I create a properly aligned partition in a new GPT table using parted by specifying percentages for start and end of the partition:

# parted -a optimal /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mktable gpt Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost.

For testing I want to create a mirrored (RAID 1) partition with a size of 1GB on /dev/sdb and /dev/sdc.

I read that fdisk cannot be used to create partitions greater than 2GB. So I use "parted" to create my partition and use fdisk to view them once created and it has NEVER been a problem until now.

I have an infotrend RAID 6 that after I use parted and look at the RAID with "fdisk -l" it reports two partitions;

Hiya people,

I need help with this.

I have this netbook, which has a Windows 7 and Ubuntu 10.04 along with a recovery tool in another partition (in fact, this is a program in that holds images of the other partitions, and you can restore them by using it).

I'd like to backup the whole hard disk, completely.

I recently added some storage to a RAID array with a single large XFS volume.

Does LVM need a partition table? 31 weeks 22 hours ago

It appears that I am able to successfully do a pvcreate on top of a raw block device, without ever taking the step of creating a partition table. I am then able to create a volume group, logical volume, and finally a filesystem, mount it, and test via dd.

It appears to work, but I need a sanity check. Is this a bad idea?

I'm trying to use preupdate to upgrade my FC10 install to FC12. However, I'm continually stopped by preupdate telling me my /boot partition is out of space. It is the default 200mb, I've deleted everything off of it I can, and I'm still short on space.
