Hi. Recently I've encountered the issue with "slow TRIM" and Sandisk SSDs, so I was told to try to disable TRIM and see what happens (thanks a lot by the way, that did it). But changing the vfs.zfs.vdev.bio_delete_disable on the fly can lead to the system crash with the probability of 50%. Is it just me or is this already known ? If it's known, why isn't this oid in a read-only list ? Thanks. P.S. My box tried to dump a core, but after a reboot savecore got nothing, so you just have to believe me. ;) Eugene.
