Hello cephers, is anyone using Fujitsu Hardware for Ceph OSDs with the PRAID EP400i Raidcontroller in JBOD Mode? We are having three identical servers with identical Disk placement. First three Slots are SSDs for journaling and remaining nine slots with SATA Disks. Problem is, that in Ubuntu (and I would guess in any other distribution as well) the disk paths for the same physical drive slot differ between the three servers. For example on Server A first disk is identified as "pci-0000:01:00.0-scsi-0:0:14:0" and as "pci-0000:01:00.0-scsi-0:0:17:0" on the other. This makes provisioning osds nearly impossible. Anyone ran into the same issue an knows how to fix this? Fujitsu support couldn't help (in fact they did not know, that you can put the controller in JBOD mode ...). I actvated JBOD via the "Enable JBOD" option in the controller management menu of the praid ep400i raid controller.
