Samba share is only 16gb for some reason | Linux For All | Page 1

Just set up a SMB server for my family to use, but the share is only 16gb. I am using a single 1tb boot drive so you know.

How are your partitions set up on the server? Let's see the contents of /etc/fstab and /etc/samba/smb.conf

#

And the output of df -hT

#

fstab, I don't see a share mounted

#

smb.conf

#

df -hT

How to create a Samba share

Samba allows for Windows and other clients to connect to file share directories on Linux hosts. It implements the server message block (SMB) protocol. This guide covers creating a shared…

Well, the short answer is because your root directory is only 16 GB. See that in the output of df -hT? Says Size 15G (it's rounding down probably).

#

What is the output of sudo fdisk -l?

one sec, lemme boot it back up

Also looks like you're on lvm (since the device name is /dev/mapper/...), so probably your initial setup was supposed to include another partition for home that is not mounted, maybe never got created. Depending on the output of the above command, and sudo lvdisplay, and sudo pvdisplay, we'll probably have a few options.

verbal robin What is the output of `sudo fdisk -l`?

#

could I make a new partition just for the share maybe?

verbal robin Jun 2, 2024, 4:17 AM

#

Well, 16 gigs is gonna be a little small for root, so we should add some to that, or just expand it out to the length of the drive

#

But your available lvm space should match the 929 g listed in the fdisk output

#

So there's plenty to work with

What is the output of sudo lvdisplay and sudo pvdisplay

#

should I just expand my root partition with cfdisk?

verbal robin Jun 2, 2024, 4:25 AM

#

Nope, cfdisk would expand the physical partition, but that's not the issue. You need lvextend, then growxfs I think. Give me a half hour or so to get to my computer and I can scratch you up the actual commands

alright, thanks!

#

also, I don't need help right this second, I have plenty of time tomorrow

Here's the easy solution: Extend your root logical volume out to the full length of the physical volume, then expand the xfs filesystem on top of that.

lvextend -l +100%FREE /dev/fedora/root
xfs_growfs /

#

If you wanted to get more complicated, you could instead grow the root to a reasonable fraction of the available space like so:

lvextend -L100G /dev/fedora/root
xfs_growfs /

Then create a logical volume for home. The issue here is that you need to be logged in to the console as root directly, not through sudo, so that you can move the /home data that already exists onto the new partition.

lvcreate -l 100%FREE -n home fedora
mkfs.xfs /dev/fedora/home # (I think, that path might not be right)
mkdir /tmp/home
mount /dev/fedora/home /tmp/home
mv /home/* /tmp/home/
umount /tmp/home
mount /dev/fedora/home /home

Then you have to add a new entry to /etc/fstab to mount this on boot, but that's also pretty easy. Just grab the UUID of the partition from sudo blkid and craft a line that matches the one for root, but with /home as the path.

It work perfectly the first way, thank you so much!
