Resizing LVM partition that is on a crypted device.

Shell Script (Bash) posted 5 months ago by marko

I installed sysrescd on an USB stick to resize a partition that had too little space on it. The hitch was that it was on an encrypted partition. This is the correct order of the commands that needed to be issued.

sda3 is the encrypted device systemvg is the name of the volume group lv_usr is the name of the logical volume

   1  cryptsetup luksOpen /dev/sda3 crypt
   2  vgcreate systemvg /dev/mapper/crypt
   3  lvm vgchange --ignorelockingfailure -P -a y
   4  lvextend -L+2G /dev/systemvg/lv_usr
   5  e2fsck -f /dev/systemvg/lv_usr
   6  resize2fs /dev/systemvg/lv_usr
