------- Comment From sekharan.com 2009-08-20 14:56 EDT------- Looks like the following patch need to be ported. http://git.kernel.org/?p=linux/storage/multipath-tools/.git;a=commit;h=d0d111d16e8af297111dc05ec84ddf06e9a109f1 Created attachment 358268 [details] Ported+Tested patch. ------- Comment on attachment From jvrao.com 2009-08-21 14:09 EDT------- I have ported and tested the community patch as mentioned in the comment#7. The port was onto multipath-tools-0.4.7.rhel5.13 source (device-mapper-multipath-0.4.7-23.el5.src.rpm) Could someone please verify whether jvrao's patch was applied to the multipath-tools and if we can close this bug? thanks ------- Comment From jvrao.com 2009-10-13 02:13 EDT------- (In reply to comment #10) > Could someone please verify whether jvrao's patch was applied to the > multipath-tools and if we can close this bug? > > thanks > Hi Any update on this? Is this into RHEL 5.4? no update yet Reassigning to Lana (documentation) so we can put a MRG 1.2 Release Note out for this (no way to get it into RHEL5.4 for MRG release). Lana, we need to make sure that we have a Release Note documenting the bogus warning issued by the device-mapper-multipath tool for RHEL5 when booting the MRG v2 kernel. ------- Comment From jvrao.com 2009-10-15 17:17 EDT------- (In reply to comment #13) > Reassigning to Lana (documentation) so we can put a MRG 1.2 Release Note out > for this (no way to get it into RHEL5.4 for MRG release). > > Lana, we need to make sure that we have a Release Note documenting the bogus > warning issued by the device-mapper-multipath tool for RHEL5 when booting the > MRG v2 kernel. > I think it is more than a documentation issue. Warning is bogus alright but it fails the command. This goes to an extent, where one can't SAN boot the MRG 1.2 on RHEL5.4 based system. The workaround is to get the SRPM, apply the patch, replace /sbin/multipath and /sbin/multipath.static, install MRG 1.2 RPMS and then proceed. Thanks, JV I did not realize that the command failed, just thought it was a warning. Reassigning... Reassigned to RHEL (per tcoughlin) Do we have any pending update on this? ping Patch applied. Reproduced this bug with kernel 2.6.33.7-rt29.45.el5rt, multipath 0.4.7-34.el5 Got the same error as customer. device-mapper-multipath-0.4.7-39.el5 fixed this problem.
