So for this you just need to leave the network up. I did some research today around this. For Debian, yes, the root FS will be remounted as read-only before shutting down/rebooting. However, the system will then stuck at sync cache, even I have left network running. I have not looked into the Linux kernel to check whether iscsi layer will send logout command to the target, but I highly suspect it won't. Here is what I am going to propose: 1. I am now trying to extend iscsistart to be capable send logout command. 2. In runlevel 0 and runlevel 6, after remounting the root FS as read-only, use pivot_root and chroot to change the root to a ramfs, similar to initramfs, which is loaded with iscsistart. Then we can logout gracefully by invoking iscsistart. Please let me know what do you think of this.
