On the old version of N9K, the size for /bootflash was around 7.5G. This size could be an issue with the new version.
Example with the old size :
bash-4.2$ df -h | grep bootflash /dev/sda4 7.5G 3.2G 4.3G 43% /bootflash /dev/loop9 190M 1.6M 178M 1% /bootflash/.rpmstore/patching bash-4.2$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

To increase the size, you need to reload the switch.
Note: During this process, you need to format /bootflash. Don’t forget to save your files (Config, Binaries, License, etc.)
Try to backup these files on one USB key to restart quickly after the disk initialization.
During the reload, you need to break the boot with CTRL + C, then enter the command: cmdline recoverymode=1 and then boot on the NXOS image.
Now, you are in loader.

Now your are in the mode boot.
Enter the following command to repartition the disk: init system

Now your disk is empty but the size have been increase.

At this time, the best way is to copy the NXOS image from USB or TFTP to bootflash and the reload.
