As far as I can tell fstrim -v always outputs 0 > bytes trimmed. (Note that I'm also a btrfs user.) I've been using the systemd timer that comes with util-linux upstream witho= ut modification, which runs fstrim weekly. That seems to work well, but to be quite honest, I wouldn't know how to tell. Sometimes I wasn't even sure it ran, so I would run it manually, and it always finished nigh-instantaneousl= y. Before that, I used the discard mount option, but apparently that's only a = good idea with high-end SSDs (not that I noticed much of a difference in everyday usage). --=20 Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup --Sig_/Dwb_dPWA9cXBly_FtArD5Jl Content-Type: application/pgp-signature Content-Description: Digitale Signatur von OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJVW1UHAAoJEL/Q5oYsiHj0mLQP/1+oXNbw0nXfgoc7QSPid0v+ HkEwn3B6GETQzKoE3QDy0r8YOALtnuKuZTYTUKt4Nx1CSWTHOYcfjXpQGqqOURf1 czrsFmr1PdC4GF0S0b258/xh6mJPUeS+GMXzmDW2iP1jCACtE4N6NwYbSTcnxuPx mEOepeNog3x8gXIh2D95Lxku5Qv4H85Ebb1Pb4vs/21koJVztWRNiYNDC61p+Gk+ oCyxjara4lyR8q5mMUmH1n1HulTbKxnBpZTEy51YNOW4BkNFbpr/pLrHjlh3OU+i 2mXAr7QO/IRn17pPZgEd+bTm/LF5000SuzsipQRAQkxV7TB1WSGFTU+mUHBpv22h Q1r2YMdc92vxAOTAUYh2XHo66e9IgWg5DnnfrR2WCaHJVJY45I03x0LB7ivPSQZN c8xhit2eds9Dg0jqw1UA9UdoJrBriXRbr9OTkqFSLOTAZyUtqURMKzFwSvadH2C8 SMgmJeGnfxg48lGFt7Ccdz0An/NWWXB9b+j8mp4W6JjH647a3jS8ysOw5Ask6HPE u3k9eCVe57DPhpCJWbrqaXCO/n2mji1nfnBVtsDD/24ZS5A1Zy5Zv8UXwCUhrZ0z NEpPwXwb1ig4k5Y3ZzTpSZNjRrGmbYr0/KQZCSjHtVsCKszqj4m2SJegnOduP4l4 i9FHM82h826H0tt5ldyZ =exdc -----END PGP SIGNATURE----- --Sig_/Dwb_dPWA9cXBly_FtArD5Jl--
