[SOLVED] sda0 - sda1 confusion between fdisk and blkid

Hello,

I am trying to install Arch on my desktop computer, a Dell Precision Workstation with a 500GB SSD.

I was partitioning the SSD by using gdisk. Now fdisk -l shows that /dev/sda looks like this:

Device              Start                      End                    Sectors              Size                     Type
/dev/sda1         2048                      1128447            1126400            550M                   EFI System
/dev/sda2         1128448            294728727       293601280             140G                   Linux filesystem
/dev/sda3         294729728        328284159           33554432           16G                     Linux swap

using gdisk -l it shows of course the same.

When I try to format /sda2 as ext4 I get no error. When I try to format sda3 as swap It says that sda3 does not exist.

so when I use blkid it shows:

/dev/sda1: UUID =.... Type = "ext4"  Partlabel="EFI"...
/dev/sda2: UUID = ... Type = "SWAP" 

There is no sda3 listed.

So it seems there is a problem with the devienames?! Why the hack fdisk/gdisk see /sda1 /sda2 /sda3 corretly but I run into an error when trying to format the file partitions?

Sometimes disk partition utilities fail to inform the kernel of partition changes. Run 'partprobe -s' to manually get the kernel to check for changes.

Re: [SOLVED] sda0 - sda1 confusion between fdisk and blkid

Thank you. A reboot, did the same Now I ran into another problem as I made gdisk to assign 550M for /dev/sda1. But when running lsblk it sees sda1 to be only 275K. Is this a problem of lsblk or gdisk? I assume the latter because when trying to format sda1 as fat32 I run into an error which says that has not enough clusters. This is really annoying I have installed arch before on my PC at home. But today, the entire thing is a pain in the ass.

Well this was solved by using cgdisk instead of gdisk. I don't have any idea why gdisk didn't work and made sda a wrong size.
