Device excluded by a filter excerpt: pvcreate encounter an error on newly prepared hard drive

Device /dev/sdc excluded by a filter

The title is one of the several issues I met when preparing new hard drives for my Linux Host.

By looking at `/etc/lvm.conf` I am 100% sure that there's no filter setup.

It turns out to be the Filesystem magic bits were remaining on my used harddrives which prevent the pvcreate command to run. Those magic bits won't be erased by `parted` tool. One must explicitly invoke `wipefs` command against the drive for magic bits cleanup. 

wipefs -a /dev/sdc

Once did this, the `pvcreate` is happy processing the hard disk for physical volume creation.

And then, I meet eglot, and gopls will also save me tons of time doing googling and api documentation navigation. But eglot-ensure is not very friendly to the good old ways of how after-save-hooks were designed to work. It makes the before/after-save-hook a buffer local variable and it does not inherit the variable's global value. So, to make before/after-save-hook work again, experts start to adding hooks to major mode specific hooks like this: emacs.md - Go (opensource.google) """ ;; Optional: install eglot-format-buffer as a save hook. ;; The depth of -10 places this before eglot's willSave notification, ;; so that that notification reports the actual contents that will be saved.
