You might also want to note that with traditional filesystems, the 'shred' utility will securely erase data, but no tools like that will work for zfs. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/z

[zfs-discuss] virtualbox rawdisk discrepancy

I have a Sun machine running Solaris 10, and a Vbox instance running Solaris 11 11/11. The vbox machine has a virtual disk pointing to /dev/disk1 (rawdisk), seen in sol11 as c0t2. If I create a zpool on the Sun s10 machine, on a USB stick, I can take that USB stick and access it through the vbox

I haven't been able to get this working. To keep it simpler, next I am going to try usbcopy of the live USB image in the VM, and see if I can boot real hardware from the resultant live USB stick. On Tue, Nov 22, 2011 at 5:25 AM, Fajar A. Nugraha wrote: > On Tue, Nov 22, 2011 at 7:32 PM, Jim Kli

It can still be done for USB, but you have to boot from alternate media to attach the mirror. On Thu, Dec 15, 2011 at 3:41 PM, Frank Cusack wrote: > Yes, except if your root pool is on a USB stick or removable media. > > > On Thu, Dec 15, 2011 at 3:20 PM, Anonymous Remailer (austria

You can just do fdisk to create a single large partition. The attached mirror doesn't have to be the same size as the first component. On Thu, Dec 15, 2011 at 11:27 PM, Gregg Wonderly wrote: > Cindy, will it ever be possible to just have attach mirror the surfaces, > including the partition tab

Re: [zfs-discuss] Can I create a mirror for a root rpool?

If you don't detach the smaller drive, the pool size won't increase. Even if the remaining smaller drive fails, that doesn't mean you have to detach it. So yes, the pool size might increase, but it won't be "unexpectedly". It will be because you detached all smaller drives. Also, even if a small
