You change it by mounting the filesystem with -o trim (or not) or calling fstrim(8). The drives either support it or they don't (they probably do). The iffy bit will be whether the controller tells the OS "this [logical] drive doesn't support TRIM", or passes it through to the physical disks, or if you can configure either behaviour. I doubt TRIM is going to be the issue here. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
