Better to check the kernel ChangeLog: * Tue Oct 10 2006 Don Zickus <dzickus@xxxxxxxxxx> [2.6.18-1.2725.el5] - kernel dm multipath: ioctl support (Alasdair Kergon) [207575] This was included in the RHEL5 GA kernel (2.6.18-8.el5) so the ioctl passthrough has been there all along in RHEL5. Unfortunately the bug that introduced the change is private, but the RHEL4 bug that it was cloned from is accessible: https://bugzilla.redhat.com/show_bug.cgi?id=168801 Regards, Bryn. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
