Any help is appreciated.
Thank you all.

based on your ss failed to write (No space left on device)

Check your server disk space.

Sorry for late reply, i think your /boot is full. Try run this command on terminal and sent it here.

sudo df -h

Thank You @ayobpro
Please see below.

As you can see your /dev/md1 (/boot) is used 100%. You can try clean up your /dev/md1 but please do it carefully.

Thank you so much for your help!
BTW, any specific measures I should take before deleting the files in that dir?
