Thanks for reporting this, we'll work on it.

Most probably it happened because of #1812, investigation is in progress

@Sheetalpamecha Can you check this, IIRC we already discussed the striped count handling during upgrade in gchat.

Hi @jirireischig, Can you please attached the full log from /var/log/glusterfs/glusterd.log ?

Are we using stripe count anywhere? If not, we need to continue and add it forever, for upgrade? How can we solve and remove unused deprecated stuff?
