Description Juan Orti 2012-05-29 21:24:59 UTC

Recently has been added support for passing TRIM requests through Luks to the block device, but dracut does not honor this option in crypttab. The versions needed are: kernel >= 3.1, cryptsetup >= 1.4.0 and systemd >= 44-11

This is my crypttab:
luks-1234567890-3bbc-5444-b1c9-1234567890 UUID=1234567890-3bbc-5444-b1c9-1234567890 none allow-discards

I have found a quick and dirty solution in this post:
