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

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 defined
Also, I logon to the host to perform 'ceph-disk activate /dev/sdb' and it is
good.
Any help is appreciated.
Thanks,
