[PATCH 0/3] Patches for some device mapper multipath issues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patch 1 just makes sure that prior to calling refreshPool we make
sure to clear the objects; otherwise, the refresh code will duplicate.
Text within patch 3 seems to indicate that entries were showing up
more than once - although those may be bug related. In any case, although
perhaps not necessary here - better safe than sorry.

Patch 2 is a rework of changes that went into 1.3.2 related to how
libvirt_parthelper generates the volume target path name that didn't
quite get the algorithm right when the device source path ended with
a non numeric value.  As it turns out it seems the naming algorithm
is much "simpler"; however, rather than just remove the attribute, I
figured it should be kept "just in case" something *needed* to add
that "p" it would be possible. It seems from output described here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/DM_Multipath/dmsetup_queries.html

That it would be possible.

Patch 3 was probably seen because Patch 2 testing occurs, so the same
"sequence" used in other disk backend based testing was attempted. As
it turns out, I don't believe the deletion for a multipath device ever
really worked. The original patch could have been reverted except that
it intermingled changes to support linking device-mapper with parthelper.

John Ferlan (3):
  storage: Need to clear pool prior to calling the refreshPool
  storage: Fix algorithm generating path names for devmapper
  storage: Fix virStorageBackendDiskDeleteVol for device mapper
