| Hi ceph-users, I recently deployed a ceph cluster with use of *ceph-deploy* utility, on RHEL6.4, during the time, I came across a couple of issues / questions which I would like to ask for your help. 1. ceph-deploy does not help to install dependencies (snappy leveldb gdisk python-argparse gperftools-libs) on the target host, so I will need to manually install those dependencies before performing 'ceph-deploy install {host_name}'. I am investigate the way to deploy ceph onto a hundred nodes and it is time-consuming to manually install those dependencies manually. Am I missing something here? I am thinking the dependency installation should be handled by *ceph-deploy* itself. 2. When performing 'ceph-deploy -v disk zap ceph.host.name:/dev/sdb', I have the following errors: [ceph_deploy.osd][DEBUG ] zapping /dev/sdc on ceph.host.name [ceph_deploy.sudo_pushy][DEBUG ] will use a remote connection with sudo Traceback (most recent call last): File "/usr/bin/ceph-deploy", line 21, in <module> sys.exit(main()) File "/usr/lib/python2.6/site-packages/ceph_deploy/util/decorators.py", line 83, in newfunc return f(*a, **kw) File "/usr/lib/python2.6/site-packages/ceph_deploy/cli.py", line 147, in main return args.func(args) File "/usr/lib/python2.6/site-packages/ceph_deploy/osd.py", line 381, in disk disk_zap(args) File "/usr/lib/python2.6/site-packages/ceph_deploy/osd.py", line 317, in disk_zap zap_r(disk) File "/usr/lib/python2.6/site-packages/pushy/protocol/proxy.py", line 255, in <lambda> (conn.operator(type_, self, args, kwargs)) File "/usr/lib/python2.6/site-packages/pushy/protocol/connection.py", line 66, in operator return self.send_request(type_, (object, args, kwargs)) File "/usr/lib/python2.6/site-packages/pushy/protocol/baseconnection.py", line 329, in send_request return self.__handle(m) File "/usr/lib/python2.6/site-packages/pushy/protocol/baseconnection.py", line 645, in __handle raise e pushy.protocol.proxy.ExceptionProxy: [Errno 2] No such file or directory And then I logon to the host to perform 'ceph-disk zap /dev/sdb' and it can be successful without any issues. 3. When performing 'ceph-deploy -v disk activate ceph.host.name:/dev/sdb', I have the following errors: ceph_deploy.osd][DEBUG ] Activating cluster ceph disks ceph.host.name:/dev/sdb: [ceph_deploy.sudo_pushy][DEBUG ] will use a remote connection with sudo [ceph_deploy.osd][DEBUG ] Activating host ceph.host.name disk /dev/sdb [ceph_deploy.osd][DEBUG ] Distro RedHatEnterpriseServer codename Santiago, will use sysvinit Traceback (most recent call last): File "/usr/bin/ceph-deploy", line 21, in <module> sys.exit(main()) File "/usr/lib/python2.6/site-packages/ceph_deploy/util/decorators.py", line 83, in newfunc return f(*a, **kw) File "/usr/lib/python2.6/site-packages/ceph_deploy/cli.py", line 147, in main return args.func(args) File "/usr/lib/python2.6/site-packages/ceph_deploy/osd.py", line 379, in disk activate(args, cfg) File "/usr/lib/python2.6/site-packages/ceph_deploy/osd.py", line 271, in activate cmd=cmd, ret=ret, out=out, err=err) NameError: global name 'ret' is not definedAlso, I logon to the host to perform 'ceph-disk activate /dev/sdb' and it is good. Any help is appreciated. Thanks, Guang |
