fstrim-all(8)		 Debian Administrator's Manual		 fstrim-all(8)

       fstrim-all - call fstrim on all mounted file systems which support it

       SSD  drives  need to be TRIMed, i. e. they need to be told which blocks
       the OS considers as "unused" (i. e. from deleted files). Withouth this,
       the write speed on SSDs becomes slower over time.

       fstrim-all  detects  which  mounted  partitions	belong	to drives that
       need/support trimming, and calls fstrim(1) on them.

       It is meant to be called from cron. There is no output on success.

       This only runs on Intel and Samsung  SSDs  as  some  SSDs  with	faulty
       firmware	 may  encounter	 data  loss problems when running fstrim under
       high I/O load (see e. g.	 https://launchpad.net/bugs/1259829). You  can
       call  fstrim-all with the --no-model-check option to disable the vendor
       check and run fstrim on all SSD drives.
