I format usb as ext4
mkfs.ext4 /dev/sda1

but XFCE does not automount the partition
my other usb (ext4 as well) shows up automatically under
/run/media/joseph/disk_name

I think you're correct that if something is automounting your USB storage
device, it's probably XFCE (or some part of it).

I don't personally use XFCE, but I'm sure others here probably do. If you
don't get any responses on this mailing list, then perhaps try the
#gentoo-xfce IRC channel. If that's also quiet, you might try another venue
that focuses specifically on XFCE, such as the official XFCE links at
https://www.xfce.org/community .

It was my error, the command should be:
mkfs.ext4 /dev/sda
The usb was auto-mounted as soon as the command finished.

It has been some time since I run it, but looking at some documentation
on-line a lot of instructions show to run:
sudo mkfs.ext4 /dev/sdX1

eg:
https://unix.stackexchange.com/questions/422656/how-to-make-an-ext4-formatted-usb-drive-with-full-rw-permissions-for-any-linux-m
Even Google AI if one search: "gentoo format usb as ext4"
it shows to run:
sudo mkfs -t ext4 /dev/sdb1

this will work but the disk will not automount in XFCE,
it should be:
sudo mkfs.ext4 /dev/sdX

[resent from my subscribed email]

"mkfs.ext4 /dev/sda" will create/format an ext4 partition taking up the 
entire device, which will then easily be automounted.

"mkfs.ext4 /dev/sda1" can work, but only if you have already created a 
partition table on /dev/sda and created at least one partition in it.  
It probably won't automount because the system doesn't know which of the 
possibly several partitions on the device should be mounted, but I 
haven't tested.

You can format the whole thing (/dev/sda) as one big ext4 volume, yes, but
unless I'm very mistaken, that's not standard practice. USB storage devices
usually have a partition table with one or more partitions defined. The
first partition would be /dev/sda1, so the usual commands to format such a
partition would use /dev/sda1, not /dev/sda.

Since you're formatting it as ext4, I suppose you only intend to use this
on Linux machines. I guess it's probably OK to format the whole device as
ext4, without any partition table. However, I would definitely advise
against it for any USB device you might use in a cross-platform
environment. I have no idea whether you can skip the partition table and
still be usable with computers running Windows or Mac OS or with embedded
systems like home printers or commercial photo kiosks.

Hello,

Same issue.
No automount usb disk ext4 formatted with cinnamon 6.
Automounting with fat32, ntfs or xfat formatted disk.

Yes, you are right.
doing "mkfs.ext4 /dev/sda1" worked, but I could only manually mount,
for automount it has to be entire partition "mkfs.ext4 /dev/sda"

If you want to run "mkfs.ext4 /dev/sda1" then first you must create a 
partition label (e.g DOS, GPT) and add a partition on the device using fdisk, 
parted, etc.  The mkfs command will error out complaining about /dev/sda1 not 
found or something like that.

If the device has no partitions on it, then "mkfs.ext4 /dev/sda" is what you 
have to run.  It will format an ext4 fs on the whole device, like a floppy 
disk.

Seeing as it's removable media I would expect most of those to have 
problems if you DID have a partition table. It's linux that's unusual in 
being happy with a partition table on removable media.

That is not the case at all. Without a partition table how would other
OSes handle, say, a USB thumbdrive with multiple partitions?

Various *nixes are the systems that don't mind if you just bang a
filesystem directly onto a storage device. Windows would (and does)
have a conniption if this is attempted.

I know linux doesn't care - has never cared, but historically you did 
NOT have partition tables on removable media. Floppy disks didn't have 
partition tables. I'm not aware of early SD cards or USB sticks having 
partition tables. It's only relatively recently with "huge" media sticks 
that partition tables on removable media have become a thing.

If you wanted to boot a Windows install from a USB stick, I'm used to 
just dd'ing the CD iso (shows how long ago that was) to the stick.

Certainly in the early days, istr Windows being unable to find a 
partition table on a USB stick.

Wol

Actually they did.  USB sticks had a partition table, and Windows would 
would only see the first partition.  It did not show you the partition 
table, but it was there.

I think the last floppy without a partition table was the 1.44 MB one 
(ok, the 2.88 MB too, but I never saw one).  Even ZIP drives had a 
partition table.
