Hmmm - IIRC, zfs loadbalances ZIL ops over available devs. Furthermore I guess, almost everyone, who considers SSDs for ZIL will use at least 2 devs (i.e. since there is "no big" benefit in having a mirror dev, many people will proably use one SSD/dev, some more "paranoid" people will choose to have a N-way mirror/dev). So why not turn the 2nd dev "temp. off" (freeze), do what you want (trim/reformat/etc) and than turn it on again? I assume of course, that the "loadbalancer" recognizes, when a dev goes "offline/online" and automatically uses the available ones, only ... If one doesn't have at least 2 devs, don't care about this home optimized setup ;-) Regards, jel. -- Otto-von-Guericke University http://www.cs.uni-magdeburg.de/ Department of Computer Science Geb. 29 R 027, Universitaetsplatz 2 39106 Magdeburg, Germany Tel: +49 391 67 12768 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
