Happy new year everyone! Wonde rif someone can help here… ( im new ) When installing rocky 9.5 - i have to delete partitions, then reclaim the space… then after install i get the attached screenshot… does that look right? - was hoping to use all space i have as i work on videos and could do with ti

That looks like the default does it.

All of the disk is allocated for three partitions:

  • 600 MiB for the EFI System Partition (that you see as /boot/efi). It is needed for booting the system
  • 1 GiB for the /boot. It is needed for booting the system
  • The rest (999 GB) for a LVM physical volume (PV)

The PV has three LVM logical volumes (LV):

  • 75 GB for “root”, the / that has OS files, logs, container images, databases, websites, and temporary files. The OS files do not need that much, unless you have some humongous third-party applications. However the used filesystem, XFS, does not support shrinking. To make this smaller would mean remove & create smaller. Practically a reinstall
  • 33 GB for swap. Again unnecessarily large, unless sleep/hibernate/etc needs it. Easier to replace with smaller
  • The rest for /home. Thus us where your movies will be.

The default Rocky9 install is once the free space is created and selected for Rocky the following partitions will be created.
1 vfat esp partition mounted on /boot/efi
1 ext4 partition for kernels mounted on /boot
1 partition that will contain the xfs /root and /home volumes.

Whether and how the /root and /home volumes occupy the remain space may require specific interventioin during the install or afterwards.

What is confusing the answer to your question is your intent for the other 3 block devices.

Hey thanks for the reply… sorry im new… intent for the other 3 blocks…

this is just how it looks after i install it…

Im hoping to claim as much free space as possible, as i will be using for video

Yes. You could have fine-tuned those sizes, but essentially if your “working data” (files for a video) do not fit within the 890 GB filesystem, then they most likely wont fit into a bit larger volume either.

Disclaimer: I don’t work with videos, so have no idea of “typical size”.

If it’s a single user home computer, it’s probably fine to have a huge /home partition with just one user in a subdir.

For somthing more serious, it’s better to use home directories for each user’s normal day-to-day files (and session state), which can then be backed up. You can then have somehing like /multimedia, /databases, /websites, which could be huge volumes that are either served or shared by multiple users.

great thanks!!! yeah the videos are around 20/50gb each… then then software would be about them same while editing that

thanks for the reply… yes at the moment its just me… i was worried i had done something wrong… being used to seeing how the mac / windows partitions look like… jsut seemed alot to me.

for the future that woudl be great, with shared users
