Once I used pvresize to shrink the pv I was left with a partition that was 20G bigger than I wanted to use and I wanted to reclaim that 20G for my ntfs partition. I assumed that I could use parted to resize this down, I was wrong. So what I did was delete the partition in fdisk and then made a new partition that had the same start but 20G short on the end. Like I said I assumed that this space was completely unused. I had a backup of my data cause of a raid 0+1 that I failed out raid 1. This worked and I now have [root@cranium][pts/1]:~# fdisk -l Disk /dev/sda: 320.0 GB, 320073629696 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 6201 49809501 7 HPFS/NTFS /dev/sda2 6329 7545 9775552+ 83 Linux /dev/sda3 7546 38913 251963460 83 Linux /dev/sda4 6202 6328 1020127+ f W95 Ext'd (LBA) /dev/sda5 6202 6328 1020096 82 Linux swap / Solaris I orig had a problem with the space being at the end and I could use it their. So I used partition magic 8.0 and moved all the data over by 20G. This took 12hrs... heh. All my data is intact so I reconstructed my raid 1. Good times. I cant believe this worked, it was voodoo. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFD7Otc48JsCLyRVlARAo27AJ44br1TcpVSLeKbzjNl15oiYzsoGQCaA3KN GVZvpMNBJ9ddBPhb+7Q60m8= =zE4d -----END PGP SIGNATURE----- _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
