The NFS client that we're using always uses O_SYNC, which is why it was critical for us to use the DDRdrive X1 as the ZIL. I was unclear on the entire system we're using, my apologies. It is:
OpenSolaris SNV_134 Motherboard: SuperMicro X8DAH RAM: 72GB CPU: Dual Intel 5503 @ 2.0GHz ZIL: DDRdrive X1 (two of these, independent and not mirrored) Drives: 24 x Seagate 1TB SAS, 7200 RPM Network connected via 3 x gigabit links as LACP + 1 gigabit backup, IPMP on top of those. The output I posted is from zpool iostat and I used that because it corresponds to what users are seeing. Whenever zpool iostat shows write activity, the file copies to the system are working as expected. As soon as zpool iostat shows no activity, the writes all pause. The simple test case is to copy a cd-rom ISO image to the server while doing the zpool iostat. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
