Thanks for testing this.

Sahina, can you test if this solve the issue with hyperconverge setup?
Maybe we can enable multipath with this patch.

 Hi 胡茂荣,

 Can you test this patch?
 https://gerrit.ovirt.org/67844

 I also need more information on your setup, to add more
 details to the commit message.

 Thanks for reporting this,
 Nir
