Ahoj, jestli chces userland, tak v primo v systemu nebo v portech o nicem nevim, ale z netu muzes zkusit samplicator http://code.google.com/p/samplicator/ O kernelovem reseni uz psal Radim. Jinak je par zajimavych utilit typu ncat nebo socat, kde ve spojeni s prikazy typu tee by to asi nejak slo, ale to by byla asi spis vyzva na nejakou olympiadu systemaku :o) -- Rudolf Cejka cejkar at fit.vutbr.cz http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic -- FreeBSD mailing list (users-l@freebsd.cz) http://www.freebsd.cz/listserv/listinfo/users-l

Ale nemel jsem cas se nad tim zamyslet nejak hloubeji. Dan -- FreeBSD mailing list (users-l@freebsd.cz) http://www.freebsd.cz/listserv/listinfo/users-l
Jak rozchodit TRIM?
Ahoj, podarilo se vam nekomu prosim rozfungovat TRIM s FreeBSD 8.3? Pokousim se o to s diskem INTEL SSDSA2CW160G3 na zakladni desce INTEL S5500BC, controller ICH10R. At jiz nastavim diskovy radic do modu AHCI, ENHANCED nebo LEGACY a na filesystemu mam pomoci tunefs nastaven flag t na enable, pri namontovani filesystemu system hlasi: WARNING: TRIM flag on fs but disk does not support TRIM Netusite nekdo prosim, co by se dalo jeste udelat, aby TRIM fungoval?

Re: Jak rozchodit TRIM?
On 05/09/12 11:39, Josef Hrabec: WARNING: TRIM flag on fs but disk does not support TRIM To znamena, ze GEOM, na kterem onen FS sidli tvrdi, ze tento disk podporu pro TRIM nema. Skutecne nema - ne, ze se nepodarilo overit zda ji ma (to by ta hlaska vypadala jinak). A GEOM to bere z identifikacnich dat, ktere o sobe poskytne sam disk. Neni nahodou INTEL SSDSA2CW160G3 jeden z tech disku, ktere defaultne podporu pro TRIM zapnutou nemaji a aby ji meli musi se nejprve zapnout ? Jestli je v IDENTIFY DATA sektoru ve wordu (ne bajtu) 169 sude cislo, tak ten disk se podporou TRIM nechlubi. Mozna jde nejak zapnout, ale v dane chvili zapnuta neni.

Re: Re: Jak rozchodit TRIM?
Ahoj, Tady se priznam moc netusim - jakym zpusobem se lze k tem informacim z data sektoru toho disku dostat? možná třeba smartctl? Milan -- FreeBSD mailing list (users-l@freebsd.cz) http://www.freebsd.cz/listserv/listinfo/users-l
Re: Re: Jak rozchodit TRIM?
Tady se priznam moc netusim - jakym zpusobem se lze k tem informacim z data sektoru toho disku dostat? mozna treba smartctl? Na smartclt jsem se dival, viz priloha.
