hi if I mount ceph with localhost, > mount -t ceph localhost:/ /mnt it fails with: mount error 22 = Invalid argument dmesg shows: [ 813.704419] ceph: parse_ips bad ip '[::1],[127.0.0.1]:/' on my machine ipv6 and ipv4 are enabled (standard debian installation). Seems like "localhost" resolves to ipv4 and ipv6 what confuses ceph kclient. As I only have ipv6 on the machine I can't test it in a real network. But maybe this also applies to DNS hostnames with both A and AAAA entries. - Thomas ceph-client-standalone/unstable-backport ref 0938669c180056f517db836f05697f8a2c41ec61 -- 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
