Accessibility of the data is also a reason, in dual boot scenarios. Doesn't need to be a native Windows driver, but something that still ties into the Explorer. There's still the option of running Solaris in VMware, but that's a bit heavy handed. -mg TT You like Windows /that much/ ? Note Sun

Windows has a user mode driver frame work thingy - came across it recently in the lsit of services on my XP box. Perhaps this could be used to host a ZFS driver on Windows? Andrew. This message posted from opensolaris.org ___ zfs-discuss mailing

Hi Sorry for the cross-posting, I'd sent this to zfs-code originally. Wrong forum. I'm looking into forensic aspects of ZFS, in particular ways to use ZFS tools to investigate ZFS file systems without writing to the pools. I'm working on a test suite of file system images within VTOC

Re: [zfs-discuss] Does iSCSI target support SCSI-3 PGR reservation ?

2007-07-27 Thread Jim Dunham
A quick look through the source would seem to indicate that the PERSISTENT RESERVE commands are not supported by the Solaris ISCSI target at all. Correct. There is an RFE outstanding for iSCSI Target to implement PGR for both raw SCSI-3 devices, and block devices.

[zfs-discuss] cloning disk with zpool

Hello the list, I thought that it should be easy to do a clone (not in the term of zfs) of a disk with zpool. This manipulation is strongly inspired by http://www.opensolaris.org/jive/thread.jspa?messageID=135038 and http://www.opensolaris.org/os/community/zfs/boot/ But unfortunately this
