Hi All hoping for some Linux genius advice
I inherited a VMWare VM cluster with a few production VM’s
they were all way over provisioned and all have 1tb Thick drives
But are only using 100gb odd each
My Main intention with this project is to reduce the size of the VHDX from 1 tb to something closer to what they are actually using.
Each VM is at times doing 1TB of backup because of the lvm disk
If there is a better way to accomplish this aside from the way i am trying i am open to that
I have used P2V to “move” a test vm on the same host but with a smaller vhdx,
The process went fine until ±97% (which i have read is common)
but now my vm doesn’t boot is says
Error Loading operating system.
Below are screenshots of the blkid and fstab and the grug.cfg of the mounted partitions on the broken VM
fstab of mounted vm drive and blkid output are images attached to this topic
I know i need to update fstab with the new uuid’s but i just don’t know which one to use.
Also how do I recreate grub? Can i use somethign like supergrub2 or do i have to go through grub file and manually change uudi?
