Well, it does seem to explain the scrub problem. I think it might also explain the slow boot and startup problem - the VM only has 564M available, and it is paging a bit. Doing synchronous i/o for swap makes no sense. Is there an official way to disable this behavior? Does anyone know if the old iscsi system is going to stay around, or will COMSTAR replace it at some point? The 64K metadata block at the start of each volume is a bit awkward, too. - it seems to throw VBox into a tizzy when (failing to) boot MSWXP. The options seem to be a) stay with the old method and hope it remains supported b) figure out a way around the COMSTAR limitations c) give up and use NFS Using ZFS as an iscsi backing store for VirtualBox images seemed like a great idea, so simple to maintain and robust, but COMSTAR seems to have sand-bagged it a bit. The performance was quite acceptable before but it is pretty much unusable this way. Any ideas would be much appreciated Thanks -- Frank _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
