I agree with Dietmar. Think of a missed ssh command to remote node (small network timeout for example), for a resize volume for example. the lun will still be there, but wrong size, and if you do a live migration, it'll crash (and maybe data corruption). ----- Mail original ----- De: "datanom.net" <m...@datanom.net> À: "pve-devel" <pve-devel@pve.proxmox.com> Envoyé: Mardi 11 Octobre 2016 08:08:43 Objet: Re: [pve-devel] LXC volumes on ZFS over iSCSI On Tue, 11 Oct 2016 06:14:14 +0200 (CEST) Dietmar Maurer <diet...@proxmox.com> wrote: > > Such things cannot work, because nodes can be offline (or worse, online > but not reachable). > Offline nodes is not a problem because when the get online their scsi bus will not have references to disappeared luns. Not reachable nodes posses another problem which will be a problem for other things too and must be handled by fencing. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael <at> rasmussen <dot> cc http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xD3C9A00E mir <at> datanom <dot> net http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE501F51C mir <at> miras <dot> org http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE3E80917 -------------------------------------------------------------- /usr/games/fortune -es says: If you always postpone pleasure you will never have it.
