If you can take a crash dump while it is "hung" and make it available, we can take a look. --matt ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

QEMU (or strictly speaking a number of image formats it supports) has its own snapshot facility, which may (or may not) be more suitable for the task in hand. Since its snapshot facility is application specific there are cases where ZFS just cannot provide anything comparable. For example we had a situation where QEMU image (snapshot) resided on one kind of storage (a really slow one), while the delta blocks generated by the writes to the volume/image were redirected to a another, dedicated (very fast) storage.Worked extremely well. -- Regards, Cyril ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS vs VXFS
Did you take a look at "Solaris ZFS and Vertias Storage Foundation File System Performance White Paper"?? It's more than just a presentation, but I guess you can extract the graphs from the paper: http://www.sun.com/software/whitepapers/solaris10/zfs_veritas.pdf Rayson On 7/13/07, Vishal Dhuru <[EMAIL PROTECTED]> wrote: > > Hi , > I am looking for customer shareable presentation on the ZFS vs VxFS , Any > pointers to URL or direct attached prezo is highly appreciated ! ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Naturally, that's a valid use. But the VMs I have are throw-away Windows VMs, with data on the host via SMB. Windows loves swapping. That and ZFS COW is something I'd rather not want combined, if not necessary. -mg signature.asc Description: This is a digitally signed message part ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
