FWIW, I've got a little bit more data on the problem of 'ls' not completing until writes to a filesystem all complete. For me it depends on the number of osd instances. With just 4 cosds, 'ls' with active writing returns immediately. At 16 cosds, 'ls' with active writing doesn't return until the writes complete. This is with current stable (commit d7af21020). Also FWIW, I'm currently unable to reproduce the slow write after truncate issue, using stable branch on server side and 2.6.38-rc4 + ceph-client master branch (commit 1afeac8b0) on client side. I'm not sure what was going on with my above report; sorry for the noise. -- Jim > -Greg > -- > 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 > -- 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
