Public bug reported:
[Description of the problem]
[SRU justification]
When running "multipathd reconfigure", which is done when one does a "service
multipath-tools restart", the file /etc/multipath/wwids does not get updated
with the wwid entries. Only the header is found.
[Impact]
The content of the file may contain stale values or remain with only the file
header if the file was removed.
[Fix]
Add a call to remember_wwid(mpp->wwid)
[Test Case]
With an up-to-date Trusty system running multipath-tools-0.4.9-3ubuntu7.13 do
the following :
$ sudo cat /etc/multipath/wwids
# Multipath wwids, Version : 1.0
# NOTE: This file is automatically maintained by multipath and multipathd.
# You should not need to edit this file in normal circumstances.
#
# Valid WWIDs:
/149455400000000006c756e31000000000000000000000000/
/149455400000000006c756e32000000000000000000000000/
/149455400000000006c756e30000000000000000000000000/
$ sudo rm /etc/multipath/wwids
$ sudo service multipath-tools restart
$ sudo cat /etc/multipath/wwids
# Multipath wwids, Version : 1.0
# NOTE: This file is automatically maintained by multipath and multipathd.
# You should not need to edit this file in normal circumstances.
#
# Valid WWIDs:
With the proposed fix, the last command would give :
$ sudo cat /etc/multipath/wwids
# Multipath wwids, Version : 1.0
# NOTE: This file is automatically maintained by multipath and multipathd.
# You should not need to edit this file in normal circumstances.
#
# Valid WWIDs:
/149455400000000006c756e31000000000000000000000000/
/149455400000000006c756e32000000000000000000000000/
/149455400000000006c756e30000000000000000000000000/
[Regression]
Only one call to remember_wwid() is added. This is what is currently done in
0.5.0
