Hi, After reinstalling a HW Node via PCS DVD, I've got some issues to add the node to cluster (previous HW was still registered there), therefore reinstalled as "Basic Storage Devices", and than added manually to Cluster successfully (after some maneuver to remove the previous registration, following some KBs) and installed Agent and Chunk Server Services. Everything seems to be running okay (pstorage ans shaman stats), but I'm unable to add the HDDs (4 HDD of 4TB each) to work as Chunk Servers, always getting the error below: [root@pcs4 ~]# /usr/libexec/pstorage/prepare_pstorage_drive /dev/sdd ALL data on /dev/sdd will be completely destroyed. Are you sure to continue? [y]y Zeroing out beginning and end of /dev/sdd... Partitioning /dev/sdd... Failed to repartition disk /dev/sdd: Could not commit to disk /dev/sdd [root@pcs4 ~]# Any idea where to start looking for? Thanks!
