Re: [zfs-discuss] How to make a ZFS pool with discs of the other machines of the LAN?
I'll drop AoE in favor of the iSCSI to export my 20 discs from Linux Debian Lenny to OpenSolaris 2008.11. Now, I believe this setup will be more compatible with OpenSolaris OS. Thanks!

Re: [zfs-discuss] How to make a ZFS pool with discs of the other machines of the LAN?
Hello! I want to know something... It is okay export the AoE discs to the virtual OpenSolaris machine through dom0? For example, in dom0 I'd like to have: from node01 via AoE to dom0 - opensolaris01 domU 500G /dev/ether/e1.0 (c3d1 /xpvd/x...@1) 500G /dev/ether/e1.1 (c3d2 /xpvd/x...@2) from node02 via AoE to dom0 - opensolaris01 domU 500G /dev/ether/e2.0 (c3d3 /xpvd/x...@3) 500G /dev/ether/e2.1 (c3d4 /xpvd/x...@4) from node03 via AoE to dom0 - opensolaris01 domU 500G /dev/ether/e3.0 (c3d5 /xpvd/x...@5) 500G /dev/ether/e3.1 (c3d6 /xpvd/x...@6) ... from node07 via AoE to dom0 - opensolaris01 domU 500G /dev/ether/e7.0 (c3d5 /xpvd/x...@13) 500G /dev/ether/e7.1 (c3d6 /xpvd/x...@14) ... The AoE devices will appear as discs in the virtual OpenSolaris machine, then I can make my big ZFS pool and export it via iSCSI/NFS/SMB using another dom0 ethernet interface... The AoE arrives to dom0 via eth1 and appear as discs in opensolaris01 domU, and then, the pool is exported as iSCSI, etc, via opensolaris01 xnf0 interface -bridged to- eth0 of the dom0. - Thiago - Sriram Narayanan sri...@belenix.org escreveu: On Sat, Mar 7, 2009 at 11:05 AM, Thiago C.
