====== Week - 12 ====== ===== 10-11 Aug ===== - Worked on testing and fixing small bugs in debian over iscsi - Tests show that it works fine as long as the round trip delay is within some bounds, else it throws ''connection timeout'' errors - The performance comparison between httpfs and iscsi show that iscsi is 3x faster. - Received the patch for pxelinux.0 from rwrc which will pass ''dns'' entry to kernel. ===== 12-13 Aug ===== - Getting ubuntu boot over iscsi ===== 14 Aug ===== - Added rescue shell option to debian. - This option can be activated by appending keyword ''rescuebreak'' in kernel parameters - It will give you ''sh'' shell when it is done with mounting root partition. - This option is primarily for developers who want to explore the invironment at this stage of booting. - When user is done with this exploration, he/she can use ''exit'' command to continue the normal boot process. - Added rescue shell to Ubantu also, - But this did not worked well as Ubuntu initramfs does something wired with standard intput and output that I dont understand :-( - Even simple echo statements don't come on the console. - There are some ''log_begin_msg'', ''log_end_msg'' functions that are used in initramfs, but I have not yet properly explored them, So I dont know how they work.
