Description
RHEL Program Management
2009-09-15 10:23:36 UTC
Ported. old version: 0.4.7-30.el5 new version: 0.4.7-30.el5_4.1 I added the following piece to /etc/multipath.conf and restarted multipath: device { vendor "STK" product "FLEXLINE 380" getuid_callout "/sbin/scsi_id -g -u -s /block/%n" prio_callout "/sbin/mpath_prio_rdac /dev/%n" features "0" hardware_handler "1 rdac" path_grouping_policy group_by_prio failback immediate rr_weight uniform no_path_retry queue rr_min_io 1000 path_checker rdac } I verified that running 'multipathd -k"show config"' ignores the configuration with old version and recognizes it correctly for new version. Customer confirmed that the issue is fixed. Updated from the customer. ========== Latest test using RHEL 5.4 with no modified rpm's kernel-2.6.18.164.2.1.el5 device-mapper-multipath-0.4.7-30.el5_4.2 kpartx-0.4.7-30.el5_4.2 multipath -ll -v2 returns expected result. dd if=/dev/zero of=/mountpoint dumps data at expected speed. Non modified initrd causes so many errors that it slows up the boot by four and a half minutes, when compared to running modified initrd: mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) --preload=scsi_dh_rdac ========== An advisory has been issued which should help the problem described in this bug report.
