Doh! I knew that, but then forgot... So, for the case of no separate device for the ZIL, the ZIL lives on the disk pool. In which case, the data are written to the pool twice during a sync:
1. To the ZIL (on disk) 2. From RAM to disk during tgx If this is correct (and my history in this thread is not so good, so...), would that then explain some sort of pulsing write behavior for sync write operations? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
