This is relative. There are indeed situations where it's acceptable to disable ZIL. To make your choice, you need to understand a few things... #1 In the event of an ungraceful reboot, with your ZIL disabled, after reboot, your filesystem will be in a valid state, which is not the latest point of time before the crash. Your filesystem will be valid, but you will lose up to 30 seconds of the latest writes leading up to the crash. #2 Even if you have ZIL enabled, all of the above statements still apply to async writes. The ZIL only provides nonvolatile storage for sync writes. Given these facts, it quickly becomes much less scary to disable the ZIL, depending on what you use your server for. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
