Issue finding ISCI target with ReadyNAS DUO

Postby sjk34 » Thu Sep 01, 2011 3:48 am

Hi , im trying to set up an ISCI target it on my ReadyNAS DUO, I followed http://readynasfreeware.org/projects/nas-iscsi-target/wiki/New_Version and http://www.markwilson.co.uk/blog/2009/09/creating-an-iscsi-target-on-a-netgear-readynas.htm however when I try and find the target with Microsoft iSCSI Initiator after adding the IP under discovery, and refreshing targets. The target does not appear, I'm pretty sure i am using all the default setting.I also have tryed to locate it in the Vsphere to use a datastore however it can't find it either. Using WinSCP I checked on the NAS and the ISCI file is there so it add correctly. I also have checked by starting using SSH and it does work. "backup:/etc/iet# /etc/init.d/rfw-iscsi-target start
Starting iSCSI Target: ietd.".

config file main parts is-
Target iqn.2001-04.com.example:readyduo.iscsi.target0
Lun 0 Path=/c/iscsi_0,Type=fileio

Thanks For your help

If the Microsoft initiator doesn't find the target chances are it wasn't started properly. To verify you can check the system logs and see what the output of the iscsi target deamon ietd is. Also you should check the output of 'ps ax' and see whether the actual target deamon [istiod1] is running. You should see multiple instances of it.

Thanks for the quick reply!
I can't see it on the list but underneath is the output from the ps ax. Which looks like it isn't running then. Any ideas what ive missed out?
Do you mind me asking where the system logs are located? or is it just the logs in the frontview?. I forgot to mention earlyer that I had data on the readyNAS before I set up ISCI but I don't think that would effect it

Issue finding ISCI target with ReadyNAS DUO

As you can see from the output, the major iSCSI daemon ietd is runing whereas the target daemons aren't. The log files to consult are stored in the /var/log directory. The most likely candidates to look for information in are system.log ans messages.

Sep 1 02:22:57 backup kernel: iSCSI Enterprise Target Software - version 1.4.20.2
Sep 1 02:22:57 backup kernel: iscsi_trgt: Registered io type fileio
Sep 1 02:22:57 backup kernel: iscsi_trgt: Registered io type blockio
Sep 1 02:22:57 backup kernel: iscsi_trgt: Registered io type nullio
Sep 1 02:22:57 backup ietd: unable to create server socket (Address family not supported by protocol) 10 1 6!

Also noticed this but I don't think it is the cause.
Sep 1 02:26:31 backup ietd: unable to lock pid file: Resource temporarily unavailable
I think this might be where it tells me where the error is, i'm not 100% sure, I can paste the rest of the logs from roughly when ISCI was installed if needed?

Thanks
Steven

No need for the complete logs. What I'd like to see though is the whole config file and I also need to know the location of it. As it seems the iSCSI target deamon doesn't find any configuration at all.

/etc/iet/ited.conf is the location the file. I did download the file using Wget but it doesn't appear to exist anymore so i copyed and pasted the information from the guide using WinSCP

Ok, the config file lokks good and the location is ok as well. What's the output of
Code: Select all
ls -al /c
? Also, did you try restarting the iSCSI stuff using
Code: Select all
/etc/init.d/rfw-iscsi-target restart
?

Hmm, looking good as well. Can you try restarting the ReadyNAS and see whether that helps?

Chances are that there was a stale pid file lying around which made the iSCSI daemon start script believe that there was already an instance up and running and thus it didn't really restart where it should have. A reboot cleans out alk the stale pid files so maybe that was all that was needed.

Hi buddy, have you had any luck on this yet?
Don't fix if it's not broken. Image
