Well, this is just not happening, everything sits on OSD2 (osd1 and osd0 have been removed in the mean time, they have been part of the first test): > > Could you run this against your crushmap? > > $ ceph osd getcrushmap -o crushmap > $ crushtool --test -i crushmap --num-rep 1 --rule 0 --show-statistics # crushtool --test -i crushmap --num-rep 1 --rule 0 --show-statistics rule 0 (data), x = 0..1023, numrep = 1..1 CRUSH rule 0 x 0 [2] CRUSH rule 0 x 1 [2] CRUSH rule 0 x 2 [2] CRUSH rule 0 x 3 [2] CRUSH rule 0 x 4 [2] … CRUSH rule 0 x 1022 [2] CRUSH rule 0 x 1023 [2] rule 0 (data) num_rep 1 result size == 1: 1024/1024 > I tried that locally and gave me a result like: > > rule 0 (data), x = 0..1023, numrep = 1..1 > CRUSH rule 0 x 0 [0] > .. > .. > CRUSH rule 0 x 1019 [1] > CRUSH rule 0 x 1020 [0] > CRUSH rule 0 x 1021 [1] > CRUSH rule 0 x 1022 [1] > CRUSH rule 0 x 1023 [0] > rule 0 (data) num_rep 1 result size == 1: 1024/1024 > > My plain-text crushmap is attached and there you see it works. So I'm curious to what output you have? I don’t know how to interpret my output. I have a [2] at all the lines of my crushtest. after running a diff between your and my crushmap, it turned out that this differed: - step choose firstn 0 type osd + step chooseleaf firstn 0 type osd that didn’t make a difference after adjusting, but having the OSD’s in my crushmap with a weight of 0 did. I reweighted them, and now things are balancing out. thanks a lot. > Wido Wolfgang _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
