You question is a good one, but I think the reason for your question may be off. If you want the ZIL in a separate location it is to cut down on latency rather than "thrashing". See: http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#Disabling_the_ZIL_.28Don.27t.29 If your concern really really is "thrashing" please consider the cost of flash memory vs a hard drive. Replacing a bad hard drive is cheaper. After a cursory glance at newegg, you can see the price per MB for: HDD $0.09 USB flash $0.64 SSD $1.875 _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
