In this video, Kevin Dankwardt discusses remote block devices. He discusses the use of targetcli. We configure a server with iSCSI space and discover it from another machine.
- [Instructor] Remote Block Storage is yet another…way that a server can make storage available…to a client's system.…On Linux we're going to use the targetcli…to set this up.…So make sure you've got it installed…and you've got the target service started…and when you enable it that means…if you reboot of course it'll get started.…And then you run the targetcli command.…Which is a complicated environment…with prompts and lots of sub-commands and so forth.…But within targetcli you can…set up the configuration.…
So the idea is…a server, a target,…can make…a disk partition or disk available…to another system, the initiator.…So instead of something like NFS…where systems can mount and see the file system,…with this we're dedicating a device…to the remote system.…And the other system sees it as a blocked device,…this remote blocked device,…and it can format it and mount it…and treat it like a disk.…
It's just provided remotely.…So we need a stored object…to use.…So here we do, say,…partition seven on our first disk.…So when we do the targetcli command we get…
