Subject: ansible stalls because the inventory is too big
Date: Mon, 28 Mar 2016 00:29:36 +0200 [thread overview]
Message-ID: <56F85ED0.5060605@dachary.org> (raw)
Hi Thierry,
When teuthology runs ansible on a newly created host as:
/home/ubuntu/teuthology/virtualenv/bin/python /home/ubuntu/teuthology/virtualenv/bin/ansible-playbook -v --extra-vars {"ansible_ssh_user": "ubuntu"} -i /etc/ansible/hosts --limit target010011010028.teuthology /home/ubuntu/src/ceph-cm-ansible_master/cephlab.yml
it stalls because there are too many hosts in the inventory (65537) and
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203193.teuthology", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203193.teuthology.yml", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203193.teuthology.yaml", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203193.teuthology.json", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/", {st_mode=S_IFDIR|0755, st_size=4096, ...}, 0) = 0
newfstatat(AT_FDCWD, "/etc/ansible/hosts", {st_mode=S_IFDIR|0755, st_size=4096, ...}, 0) = 0
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203194.teuthology", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203194.teuthology.yml", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203194.teuthology.yaml", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/etc/ansible/hosts/host_vars/target010011203194.teuthology.json", 0x7fc8f1a4f0, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
takes forever. This is running on an ARMv8 virtual machine:
Cheers
