Hi, all.
I want to know how to compile iscsid with iscsi modules already built
into the kernel.
I built a kernel with the following options selected in .config so that
iscsi_tcp, libiscsi and scsi_transport_iscsi are built into the kernel.
CONFIG_ISCSI_TCP=y
I compiled iscsid shipped with open-iscsi-2.0-871 and run it.
Then, I hit the following error and iscsid won't come up.
Mar 23 04:58:03 ubuntu iscsid: Missing or Invalid version from
/sys/module/scsi_transport_iscsi/version. Make sure a up to date
scsi_transport_iscsi module is loaded and a up todate version of
iscsid is running. Exiting...
I understand that the error is telling that it can't read version of
scsi_transport_iscsi from /sys/module directory.
But, since my scsi_transport_iscsi is built into the kernel,
there is no /sys/module/scsi_transport_iscsi direcotry.
So, I removed the piece of codes in iscsid.c to avoid checking
/sys/module/scsi_transport_iscsi/version to run iscsid.
if (iscsi_sysfs_check_class_version()) {
log_close(log_pid);
exit(1);
}
However, I don't think removing the codes is not a correct way
to build iscsid with iscsi modules already built into the kernel.
Can anybody tell the correct way to make iscsid when iscsi modules
are built into the kernel?
Thanks,
Kim
