It is much appreciated.=20 If the original metadata written by hostA changes by "mdadm --assemble"= running on hostB, will mdmpd be able to recover the failed links on ho= stA when they re-surface? I am asking this because, I guess unless host= A goes down, hostA reflects the new metadata written by hostB. Will mdm= pd take the new uuid into account?=20 Not entirely OT, but devabel gets to the see the same uuid/serial numbe= rs on the shared luns across hosts. It would have been cool if mdadm co= uld too, right?
