I am trying to get iSCSI support into my Yocto build, however I am finding that it is not going very well...
I have my kernel configured with all the necessary options (I think...): iSCSI Boot Firmware Table Attributes module (SCSI_ISCSI_ATTRS) Linux-iSCSI.org iSCSI Target Mode Stack (ISCSI_TARGET) Generic Target Core Mod (TCM) and ConfigFS Infrastructure (CONFIG_TARGET_CORE) Userspace-driven configuration filesystem (CONFIGFS_FS) Now I am trying to get a program installed to configure the iSCSI setup. I found that there are no recipes for targetcli (which I would prefer to use if there is one out there or if someone is willing to guide me through it), so I found a recipe for lio-utils, which I have modified to build into my image. So far, I can run the LIO utilities, but am always getting errors stating that the device is busy. How can I get around those? Internet searches are fruitless. Any thoughts? My output is below. I suspect that it has something to do with the fact that /dev/sdb1 is already mounted on /media/sdb1 (though it really isn't - you can see that in the umount command at the end...). Can I prevent the system from trying to mount those? It appears that it is doing it via udev, but even if I move the mount script out of it's location, it still is happening. What am I doing wrong?
