Timothy Asir has uploaded a new change for review. Change subject: gluster: create pv with custom dataalignment value ......................................................................
gluster: create pv with custom dataalignment value Blivet creates pv with 1mb dataalignment forcefully for whatever given value. So that we have used vdsm.storage.lvm module to create pv. But due to some lvm configuration VDSM also creates pv with 1mb dataalignment value. Seperate bug oppend for vdsm to fix this issue in https://bugzilla.redhat.com/show_bug.cgi?id=1235086 This patch uses lvm pvcreate command as a workaround till this bug fixed in either vdsm or blivet.
