I am trying to get back into the unix game for some storage projects we have got going. We would love to use joyents smartos (based on illumos) for that.
Working with it is a real joy (setting up vms etc) but i can't get iscsi to work.
I would love to simply share a zfs device as an iscsi connection point but cant get it to work. I also cant get smb or nfs to work, but those properties at least exist and i am sure they would work.
The documentation i can find seems a little all-over-the-place with some old solaris, new solaris, illumos stuff etc. Which is understandable since it is such a new release though.
Does anybody have any pointers ?
I already tried
zfs set shareiscsi=on zones/name
which results in "unknown property". And its not listed in the zfs properties anyway.
I also tried
sbdadm create-lu /dev/zvol/rdsk/zones/
but this results in
sbdadm: unknown error
itadm also is not available and not service containing iscsi is listed in "svcs".
Any help is greatly appreciated.
Update: It seems iscsi is provided by COMSTAR and not in the same way that old solaris did it so the set shareiscsi is not supported because of that.
Update: i found out that the stmf service needs to be started for it (related to COMSTAR). sadly its in maintainance mode (svcs|grep stmf) log in /var/svc/log/system-stmf:default.log says:
svc-stmf: Unable to load the configuration. See /var/adm/messages for details
/var/adm/messages says:
svc:/system/stmf:default: Method "/lib/svc/method/svc-stmf start" failed with exit status 1.
system/stmf:default failed: transitioned to maintenance (see 'svcs -xv' for details)
probably a driver is missing, but which one ? and how do I install it ?
@mgoetzke thanks, how could one trace back down to backing storage from iSCSI target name in that set-up? – poige – 2017-01-27T11:00:28.977
@poige not sure I can follow. What exactly is it you need ? – mgoetzke – 2017-02-01T14:20:07.047
you have some TARGETNAME (
iqn.2010-08.org.illumos:02:iscsi-100T
) — how do you find its backing store (zones/iscsi
)? – poige – 2017-02-01T18:46:56.220@poige I don't know right now, but I am sure the command line tools I used above also have options to backtrack the configured state. You might have to look into them – mgoetzke – 2017-02-16T08:19:53.537
Useless reply; surely I did. I assume you didn't though. :-> – poige – 2017-02-16T09:01:18.463
@poige well you didn't write that and sometimes people don't look, I did not want to offend just say that is where I would start. If you didn't find it there maybe ask in the smartos-discuss group unless you did that too. – mgoetzke – 2017-02-17T09:49:49.637
2btw: this will get lost on reboot. in order to persist you should create a script that will execute on startup. – mgoetzke – 2012-03-18T12:15:13.097
1create a script that will execute on startup and place it in /opt/custom/smf along with an smf file that executes the script on startup. – mgoetzke – 2012-03-18T12:25:27.703
it might be possible to use "stmfadm create-lu ..." with option --lu-prop alias=myname in order to create a consistent name instead of creating new names all the time ... that might make it easier for clients to autoreconnect to the iscsi device" – mgoetzke – 2013-01-08T12:33:52.317
Excellent instructions. I followed these on my smartOS machine using 20130725. It appears to be only possible in the global zone. – Matt Connolly – 2014-02-08T04:45:54.147
