„ceph-disk list“ I get the following Traceback:

I’m running ceph 9.2 on Ubuntu 14.04.3 LTS on HP Hardware with HP P400 Raidcontroller. 4 Node Cluster (3 of them are Mons), 5-6 OSDs per Node with journals on separate drive.

A tentative workaround is to replace in /usr/sbin/ceph-disk

def block_path(dev):
    path = os.path.realpath(dev)

with

def block_path(dev):
    path = get_dev_path(os.path.basename(os.path.realpath(dev)))

Is that exclamation point supposed to be there??

Look at http://man7.org/linux/man-pages/man4/cciss.4.html

The device naming scheme is:

/dev/cciss/c0d0         Controller 0, disk 0, whole device
/dev/cciss/c0d0p1       Controller 0, disk 0, partition 1
/dev/cciss/c0d0p2       Controller 0, disk 0, partition 2
/dev/cciss/c0d0p3       Controller 0, disk 0, partition 3

/dev/cciss/c1d1         Controller 1, disk 1, whole device
/dev/cciss/c1d1p1       Controller 1, disk 1, partition 1
/dev/cciss/c1d1p2       Controller 1, disk 1, partition 2
/dev/cciss/c1d1p3       Controller 1, disk 1, partition 3
