NAME

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

DESCRIPTION

       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.
