December 22, 20232 yr 5 hours ago, gpetr said: iqn.2005-12.com.bosch:unit00075fb6cfdd (NOT AUTHENTICATED) What kind of machine is this Initiator? It seems that it sends requests that the Target can't handle and that's why you see those messages. Maybe these are proprietary requests that this BOSCH machine is using, maybe try to look on the Initiator side and see if you can deactivate them.

December 26, 20232 yr Hello The way I have it now is a single 8TB drive using Unassigned Drives plugin and using it with the iscsi plugin as an block device over dedicated 2.5gig nic to my w10 desktop. This is working just as expected and full speed. Then I have tried an fileio (diskimage) on my 2*500GB sata ssd zfs-mirror pool, same connection, here I get max 54MB write and 250-300 read Also tried an fileio on an zfs drive in the array, same connection, here I get 6MB write and 2-300MB read. In both cases, if I transfer smaller files, they gets copied instant, I think this is the files may first just get dumped into ram. The way slower for the array drive makes sense as its part of the unraid array and so parity is written at the same time too, but what else this is telling me as the write speeds are way slower than expected in both cases is that iscsi fileio has a massive overhead. Does this seems correct or may it be something missing on my side?

For ZFS it would be better to create a subvolume share that subvolume on the pool and then format it correctly on the initiator side. 34 minutes ago, isvein said: fileio has a massive overhead. Exactly.

Hmm that I'm not sure how to do. Edit: Found out how to make an zvol Did the same test again, the zvol on the array works just as bad, it even crashed the iscsi as my w10 desktop suddenly reconnected, but Im pretty sure this is NOT the intended way to use an zvol so it makes sense. The one on the ssd mirror on the other hand worked just fine! Saturated the 2.5gig nic so this works just as I hoped for Edited December 26, 20232 yr by isvein
January 5, 20242 yr On 6/5/2023 at 5:36 PM, MrOz said: Ok, I figured out what I needed to do to get that command to run. I was too tired to see it correctly. It does show "not supported" What settings can I change to fix this? Did you ever figure out how to get this working? Trying to do the same setup for a lab setup and coming across the same issue.
January 9, 20242 yr I spent some time getting this to work from a Unraid server to a Windows computer and thought I would type out some instructions even just for my own benefit when I go to do this again and forgot how it works. This is for using a File IO setup. 1. From the File IO tab - Select the path for the share to store the image file - type a name for the file - select size - Example 2000g being 2TB - Select Write back as True 2. On the initiators tab - use the Create Target -> Leave the name blank and it will auto assign a name. I could never get it to work with my own name. -> hit add target 3. On windows computer open iSCSI Initiator - On the Configuration tab -> copy the initiator Name - Will be something like: iqn.1991-05.com.microsoft:*computername* 4. Back on unraid on the initiators tab - for Create IQN, select the target created in setup 2. - Enter the Initiator name copied from the windows computer - select add IQN 5. Create LUN - Choose the IQN created then select the fileIO created in step 1 - Select add LUN 6. Add Mapping - Select the Target again, and the Initiator name of the Windows PC. - For Lun Map number use "0" if there is only one Lun created, if you have more then one then use 1,2 etc. - For Lun or Backstore name, it will be fileio;*fileioname* -> for example mine was fileio;ISCSI-2 - I leave Write protect as false, just as default. - Select add Map *pro tip, when selecting some of these options if I double clicked the line it would bring up some of the available name options. for example fileio;ISCSI-2 for the LUN name. 7. back on the windows computer - On the target tab enter the IP as target and hit Quick connect. * Note it will sometimes it will auto find the targets - Select the name of the target from the list - Click connect - I leave the next window as default, and click okay. 8. Format the drive - In disk Management, initialize the disk, create a volume and format the disk. Feel free to add to this or change as needed.

I would recommend using a whole block device, so to speak a whole disk instead of a image (FileIO) since write speeds will be much higher on a physical block device, this would be my only advice.
January 13, 20242 yr I'm getting relatively high disk response time / latency. Using zvol method (not fileIO) on single zfs 16TB HDD over 1G ethernet. The connection speed is around 100mb/s, which is expected, but when copying steam games from local drive shows high latency jumping between 200~2000ms and mostly stay around 1500-2000ms. I don't know if this is normal and haven't tested SSD performance. Update: Tried coping video file and latency rests at consistent 500ms, but can it be further reduced?

This is the log from the Initiator as far as a can tell correct? Could it be the case that your NIC is reconnecting at times? Please also check if you have a old config somewhere on your Initiator. Just to double check, the IQN matches the one on the Target correct?
February 14, 20242 yr Hey, thanks for your response At the moment the client (initiator) is off, and I'm still getting the spam, so it can't be the initiator... I'm getting these messages every minute. The initiator name in the message is the random initiator name that was created at some point when I was still figuring out how to make iscsi work. s4-unraid-diagnostics-20240214-1007.zip
