Hi.

I have a simple question. Is it safe to place log device on another  
zfs disk?


I'm planning on placing the log on my mirrored root partition. Using  
latest opensolaris.

Re: [zfs-discuss] Default 'zpool' I want to move it to my new raidz pool 'gpool' how?

You can't get rid of rpool. That's the pool you're booting from. Root  
pools can only be single disks or n-way mirrors.


As to your other question, you can view the snapshots by using the  
command "zfs list -t all", or turn on the listsnaps property for the  
pool. See  http://docs.sun.com/app/docs/doc/817-2271/ghbxt?a=view for  
more info.

Hi guys

I am new to Opensolaris and ZFS world, I have 6x2TB SATA hdds on my  
system, I picked a single 2TB disk and installed opensolaris  
(therefore zpool was created by the installer)


I went ahead and created a new pool "gpool" with raidz (the kind of  
redundancy I want. Here's the output:


@server:/# zfs list
NAME USED  AVAIL  REFER  MOUNTPOINT
gpool119K  7.13T  30.4K  /gpool
rpool   7.78G  1.78T78K  /rpool

Now, I want to get rid of "rpool" in its entirely, I want to migrate  
all settings, boot records, files from that rpool to "gpool" and  
then add the member of rpool c8t0d0s0 to my existing "gpool" so that  
I have a RAIDZ of 6x drives.


Any guidance on how to do it? I tried to do zfs snapshot

# zfs snapshot rp...@move


But I don't see the snapshow anywhere on rpool/.zfs (there is  
no .zfs folder)


Thanks
