About disk partitioning

Hello there. I have recently installed SLED SP1 on my laptop. Everything has been running flawlessly, but I cannot understand the way my SSD is partitioned. I have a 256 GB SSD, of which only a small part is devoted to my files, whereas the majority called XFS remains empty. Why is this happening? As you may have guessed, I chose the suggested partitioning during the installation. Thanks in advance.

Hi
Can you show the output from;

lsblk
mount

Unfortunately, I have been away from home and will not have access to my laptop till Thursday. I will check what you suggested then. Thanks for your immediate response anyway.

Hello again. Here is the output you asked for:

Thanks in advance.

Hi
So it didn’t allocate all disk space during install (likely selected system defaults?), you could extend /home (p3) or just create a p5 and give it a mount point like sat stuff?

Thanks. I’m also considering choosing MBR instead of UEFI for the imminent installation of SP2, so I’ll keep everything in the same partition.

Hi
I would stick with UEFI, I have SP2 running here fine with UEFI and it’s the way going forward. If secure boot is an issue, just disable and use the normal efi file rather than shim.

OK, I’ll follow your advice.
