i need a little help reducing my crypt partition. when i first installed debian, i used a rather standard /boot on /dev/hda1 and crypt on /dev/hda2, using LVM for the rest of the partitions.
i've been following this[1] resize guide and i am at step 5, having already resized my logical LVM root and physical LVM volumes successfully. /boot is about 230M and the rest (~39G) is allocated for crypt. inside crypt i now have a 20G physical LVM volume with 512M swap and 10G root logical volumes, and ~10G free space. now i just want to reduce crypt so it is also about 20G, leaving the rest of the ~19G as free space on the drive. the final step it seems, before praying, is to delete /dev/hda2 with fdisk and recreate it with the smaller size. i'm wondering what the correct size should be; i'm afraid i might make it too small and then corrupt everything somehow. i don't have the same layout as in the guide since ubuntu does it a little differently with extended partitions, so a little assistance going through fdisk would be appreciated. below is some info from fdisk and LVM, let me know if you need more info. thanks so much 1. https://help.ubuntu.com/community/ResizeEncryptedPartitions#Detailed_resizing_.2BAH4_Reducing_an_encrypted_partition $ sudo fdisk -l Disk /dev/hda: 40.0 GB, 40007761920 bytes 255 heads, 63 sectors/track, 4864 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x3f423f42 Device Boot Start End Blocks Id System /dev/hda1 * 1 31 248976 83 Linux /dev/hda2 32 4864 38821072+ 83 Linux Disk /dev/dm-0: 39.7 GB, 39751725568 bytes 255 heads, 63 sectors/track, 4832 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Disk /dev/dm-0 doesn't contain a valid partition table Disk /dev/dm-1: 10.8 GB, 10850664448 bytes 255 heads, 63 sectors/track, 1319 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Disk /dev/dm-1 doesn't contain a valid partition table Disk /dev/dm-2: 536 MB, 536870912 bytes 255 heads, 63 sectors/track, 65 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Disk /dev/dm-2 doesn't contain a valid partition table $ sudo pvdisplay --- Physical volume --- PV Name /dev/dm-0 VG Name graveyard PV Size 20.00 GB / not usable 3.81 MB Allocatable NO PE Size (KByte) 4096 Total PE 5119 Free PE 2404 Allocated PE 2715 PV UUID HMRsf8-1ePs-J33c-4tQu-7MtA-V6dv-O0U10R $ sudo lvdisplay --- Logical volume --- LV Name /dev/graveyard/root VG Name graveyard LV UUID C7bLop-WiHU-dwRy-3jBR-k1QP-rQEH-X9Zchr LV Write Access read/write LV Status available # open 1 LV Size 10.11 GB Current LE 2587 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:1 --- Logical volume --- LV Name /dev/graveyard/swap_1 VG Name graveyard LV UUID yyUTnD-JVGR-BzVb-krSR-Mswq-aYoE-9YYfJt LV Write Access read/write LV Status available # open 2 LV Size 512.00 MB Current LE 128 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:2 -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
