...ystem/swap, swap - system/home, ext3 mounted as /home (431GB) I need to shrink system/home to 80GB (currently there is 57GB used) and use free space to create another logical volumes. My scenario is 1. reduce ext3 fs size to 80GB by using resize2s 2. reduce system/home size by using lvreduce 3. create another logical volumes Questions 1. How can i be sure that i will shrink ext3 to exact size 80GB and that the same will lvreduce do? I do not want to cut from ext3 filesystem if i will reduce logical volume too much 2. Can you please send me commands to achieve 1) and 2...

I know lvextend and lvreduce commands but I prefer to use the GUI which is less prompt to errors (specially when shrinking your volume). Still, I?m talking about any known live CD which contains system-config-lvm or any other GUI tool. Thanks --- This emai...

Hi. I want to make a snapshot from a logical volume and noticed that there must be enough free disk space in the volume group. Actually there is no free disk space left. How do i shrink online /var without losing any data or restore from backup? I do not have physical access to the server. Specs: Dell PE SC1430 with a 5/i RAID Controller one RAID 1 array from the Dell RAID controller 2

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

Hi, Something I haven't done before is reduce the number of volumes on my server.. Here is my current disk setup..

I have a Centos 7 install using EXT4 on LVM. Its running as a VM inside KVM. Issue I have run into is that fstrim does not work due to the LVM. Without fstrim snapshots have gotten huge. Is there a way convert it from LVM to non-LVM without a complete reinstall?
