ceph 安装过程中问题解决

• No module named pkg_resources

yum install python-setuptool

---

• Ceph 时钟偏移问题 clock skew detected 解决方案
  1.安装内网ntp服务
  2.修改ceph.conf，添加以下内容
  mon clock drift allowed = 2
  mon clock drift warn backoff = 30
  然后重启

systemctl restart ceph-mon.target

---

• application not enabled on 1 pool(s)
  执行ceph health detail，然后找到哪个pool启用即可

ceph osd pool application enable .rgw.root rgw

---

• 配置s3cmd，添加以下内容，不建议用s3cmd --configure配置（太麻烦）

yum -y install s3cmd
cat /root/.s3cfg
[default]
access_key = xxxxxxxxxxxxxxxxxxxxxx
secret_key = 123
host_base = 10.10.10.11
host_bucket = 10.10.10.11/%(bucket)
use_https = False

• mkfs.xfs无法格式化问题cannot open /dev/sdm: Device or resource busy

for i in dmsetup ls |awk '{print $1}';do dmsetup remove $i;done
然后再格式化硬盘
parted -s /dev/sda mklabel gpt mkpart primary xfs 0% 100%
mkfs.xfs /dev/sda -f
