From mboxrd@z Thu Jan 1 00:00:00 1970 From: jthumshirn@suse.de (Johannes Thumshirn) Date: Thu, 22 Jun 2017 15:06:00 +0200 Subject: Booting from NVMe over Fabrics Message-ID: <20170622130600.GK5670@linux-x5ow.site> Hey Folks, I know this is a rather unpopular topic, but one day someone will come up with it and I'd like to be prepared. The big blocking points Hannes and I have discovered are a) discovery (no pun intented) and b) connection establishment. Currently we need the nvme-cli for both and thus can't do a auto connect from the kernel at boot time (iscsiadm or fcoemon anyone?). We could do it the very same way, i.e. fire up nvme connect-all from the initrd (and pray we have /etc/nvme/discovery.conf) but the hand-over of parameters from the HCA/HBA firmware is a major PITA at least from iSCSI (ibft doesn't fix things). So do you (especially the ones of you in the nvmexpress committe) have special plans or do we repeat or previous errors?
