*** Bug 189834 has been marked as a duplicate of this bug. *** *** Bug 189831 has been marked as a duplicate of this bug. *** dmsetup remove_all issues an instruction to the kernel device-mapper to attempt to remove all its devices. This is similar to 'lvmchange -R' in the original version of LVM on 2.4. To reset /dev/mapper afterwards you need to issue 'dmsetup mknodes'. Perhaps there's a case for providing a new option that runs both commands at once. Included in 1.02.08. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. 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 the solution and/or where to find the updated files, please follow the link below.

Description of problem: I am running RH4 U3 and when i issue dmsetup remove_all i do not see the device links removed from /dev/mapper/<MP Device>. dmsetup table shows the devices were removed and /var/log/messages also shows the device removed. Issuing multipath -F does not help. Version-Release number of selected component (if applicable): RH4 U3 # rpm -qa | grep -i device device-mapper-1.02.02-3.0.RHEL4 device-mapper-multipath-0.4.5-12.0.RHEL4 How reproducible: 1. Export the storage volumes to the host 2. Issue "echo "scsi add-single-device"" to add the device to the scsi layer 3. issue multipath command (i had disablad user_friendly_names) The following /etc/multipath.conf was used defaults { udev_dir /dev polling_interval 10 selector "round-robin 0" path_grouping_policy multibus getuid_callout "/sbin/scsi_id -g -u -s /block/%n" prio_callout /bin/true rr_min_io 100 rr_weight priorities failback immediate user_friendly_names no } devnode_blacklist { wwid 26353900f02796769 devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z]" devnode "^cciss!c[0-9]d[0-9]*" devnode "sda" } devices { device { vendor "3PARdata" product "VV" path_grouping_policy multibus path_checker tur no_path_retry 60 } } 4. ls /dev/mapper control 350002ac00d58003e 350002ac00d58003e1 5. dmsetup remove_all From /var/log/messages multipathd: dm map 350002ac00d58003e removed 6. ls /dev/mapper control 350002ac00d58003e 350002ac00d58003e1 -- I still see the link 7. multipath -F # ls /dev/mapper control 350002ac00d58003e 350002ac00d58003e1 -- I still see the link 8. dmsetup dmsetup table No devices found 9. cat /proc/partitions -- shows no dm devices. Things work correctly if dmsetup remove <device> is used. This is also causing issues when you use kpartx command it is not adding the partition existed on the device with the following error: Apr 24 14:42:13 sqa-dell2850-01 hal.hotplug[16195]: timout(10000 ms) waiting for /block/dm-20 Apr 24 14:42:13 sqa-dell2850-01 hal.hotplug[16200]: timout(10000 ms) waiting for /block/dm-20 There is no /dev/dm-20 created Steps to Reproduce: 1. 2. 3.
