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. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below.
