POST doesn't overwrite it? > > --matt Hello Matthew, No, it is not persistent, it will create a new RAMDISK at boot time. But like in my case, I have a persistent ZIL that is mirrored, with small changes on this script you can have a persistent ZIL. But in my case, I have a special stuff, I have the ZIL at RAMDISK mirrored and two different RAM and protected by battery, when I make a shutdown it dump all information from RAMDISK to a SSD, and when I boot, it does the opposite, create the RAMDISK and dump from SSD to RAMDISK and I just attach it once again to the pool.
