Hi there, am setting up a new ceph cluster. I wondered if there was a problem with the following crushmap, my clients immediately lock up when I use this. I have 4 nodes each with 2 disks and 2 osd's # devices device 0 device0 device 1 device1 device 2 device2 device 3 device3 device 4 device4 device 5 device5 device 6 device6 device 7 device7 # types type 0 device type 1 host type 2 root # buckets host host0 { id -1 # do not change unnecessarily alg straw hash 0 # rjenkins1 item device0 weight 1.000 item device1 weight 1.000 } host host1 { id -2 # do not change unnecessarily alg straw hash 0 # rjenkins1 item device2 weight 1.000 item device3 weight 1.000 } host host2 { id -3 # do not change unnecessarily alg straw hash 0 # rjenkins1 item device4 weight 1.000 item device5 weight 1.000 } host host3 { id -4 # do not change unnecessarily alg straw hash 0 # rjenkins1 item device6 weight 1.000 item device7 weight 1.000 } root root { id -5 # do not change unnecessarily alg straw hash 0 # rjenkins1 item host0 weight 2.000 item host1 weight 2.000 item host2 weight 2.000 item host3 weight 2.000 } # rules rule data { ruleset 1 type replicated min_size 2 max_size 2 step take root step chooseleaf firstn 0 type host step emit } # end crush map -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
