Thanks to Cyril Plisko, Casper Dik, Kevin Buterbaugh, Jagannath Gopalakrishnan. UFS doesn't provide a public ioctl() interface for per-file Direct I/O, as VxFS does. Though, it provides a library function that issue the private ioctl call : directio() (man directio) Note that activating directio on an opened file will affect all other processes accessing this file. --- Sebastien DAUBIGNE sdaubigne@bordeaux-bersol.sema.slb.com <mailto:sdaubigne@bordeaux-bersol.sema.slb.com> - (+33)5.57.26.56.36 SchlumbergerSema - SGS/DWH/Pessac -----Message d'origine----- De: DAUBIGNE Sebastien - BOR ( SDaubigne@bordeaux-bersol.sema.slb.com ) [SMTP:SDaubigne@bordeaux-bersol.sema.slb.com] Date: mercredi 19 mars 2003 15:09 @: sunmanagers@sunmanagers.org; 'veritas-vx@mailman.eng.auburn.edu' Objet: UFS direct I/O Is there any method to activate UFS direct I/O on a per-file basis (not on per-filesystem basis with the forcedirectio option).. I know VxFS has an ioctl call for this (VX_DIRECT), but I didn't find the equivalent UFS option. I will summarise. --- Sebastien DAUBIGNE sdaubigne@bordeaux-bersol.sema.slb.com <mailto:sdaubigne@bordeaux-bersol.sema.slb.com> - (+33)5.57.26.56.36 SchlumbergerSema - SGS/DWH/Pessac _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagers _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Thu Mar 20 06:02:15 2003
