Re: automatically running fstrim

[Phil Karn <karn@xxxxxxxxxxxx>]

Thanks. My problem is that I've been running some workloads that can 
gobble up the SSD erased page pool rather quickly. It's a Perl script 
feeding a large number of email messages to procmail, one at a time. I 
think this creates and deletes a lot of temporary files. While XFS 
delayed allocation normally keeps such files from going to disk, I think
 procmail defeats this with fsync() to keep mail from ever being lost.

So I've simply been running fstrim by hand a lot so I don't have a 
repeat of the system lockup I had a few days ago that I am pretty sure 
was due to my OCZ Revo drive not handling garbage collection very 
gracefully.
