It is partially correct. With the ZIL disabled, you could lose up to 30 sec of writes, but it won't cause an inconsistent filesystem, or "corrupt" data. If you make a distinction between "corrupt" and "lost" data, then this is valuable for you to know: Disabling the ZIL can result in up to 30sec of lost data, but not corrupt data. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
