Interesting strategy, can't believe I've never heard of this one before.

Would it be more pragmatic to allocate a swap file instead? Something that provides a theoretical benefit in the short term vs a static reservation.

Because adding swap file is instantaneous, removing one that is in use can take a longtime unless you reboot the OS so you can't just nuke it quickly.

Let's get crazy

1. swapoff

2. drop disk cache (1)

3. panik!?!

hrm, seems ok

[esseph]

Actually there should be a 'sync' as step 2 :)

it has been 3 days since esseph has nuked prod

"That's fine let's just restore from the backups."

"..."

"Oh no, restore failed"

(I feel like this is about 9 out of 10 companies these days)

Reminder to regularly test backup restoration!
