We have some raid controllers, namely: RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05) We would like to use SSDs for raid1/5/6 setups but found out that the drivers don't seem to support the trim command yet. Are there any ideas how to make that work, or are there any other controllers that already support this? -- Regards, Stephan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
