you can say "chimoora" instead of "cow of tailed snake" if you want. its a good pun.

i ramble about aerospace sometimes
I take rocket photos and you can see them @aWildLupi

I have a terminal case of bovine pungiform encephalopathy, the bovine puns are cowmpulsory

they/them/moo where "moo" stands in for "you" or where it's funny, like "how are moo today, Lupi?" or "dancing with mooself"

an old sysadmin once told me "on every drive, write 20gb to a file as ballast to delete in an emergency if you run out of disk" and in my old age, i am passing it on to you

Absolute galaxy brain move. Incredible. I stand in awe. This person was the only true sysadmin, the rest of us were just pretenders to the throne.

An old sysadmin who has kept up with the times, back when they were a young sysadmin it would have been maybe a 200k file rather than one bigger than the entire disk!

yeah it's not adjusted for inflation on prod, so furry sysadmins may have issues

I follow this practice, but a few things to note:

The size of the buffer should be proportional to the capacity of the disk/volume. I aim for 15%.
Instead of a buffer file, I use a buffer partition - this way I can control the location of the data on the disk itself, placing it at the end of the disk (where performance is worse), therefor reserving the faster performing areas for actual data.
- This only applies to HDDs. I still do this on SSDs just for consistency but it has no impact on performance.
- This does have the caveat that you need to be using a filesystem for the data partition that supports online extending (or offline extending if you can deal with that).

fwiw pretty much all spinning disks have used zoned recording since the mid-00s, the performance is not worse towards the end of the drive anymore

I might adopt this, its a good idea

This trick has saved my bacon more than once. Btw you don’t have to be the admin to do this.

Nire Bryce @NireBryce4/13/2023, 8:43 PM

even if you're restricted to a user, at the point you're doing this you're administering a system imo

@AndreL4/13/2023, 9:33 PM

Fair enough. I just thought back over the times this has saved me, and realized that I never had root access.

Nire Bryce @NireBryce4/13/2023, 10:38 PM

yeah! i wrote about it because i was reminded by having 6kb left in my home dir thanks to Go and a github install script sudo curl | bash misfiring and installing Several Gigabytes of dependencies for something.

it's good additional context :)

if you get lucky you inherit a system that already has thousands of ballast files because the previous owners didn't believe in log rotation

I think I did this by accident once when I forgot to clean up a large log file I was poking at 😆

I later deleted it when the host was having issues and my manager was like "..."
