问题
最近想把一个现有的 Ceph 客户端升级为最新的 M 版：
[root@overcloud-ovscompute-0 ~]# rpm -qa | grep ceph
puppet-ceph-2.4.1-2.el7ost.noarch
libcephfs1-10.2.10-17.el7cp.x86_64
ceph-base-10.2.10-17.el7cp.x86_64
ceph-osd-10.2.10-17.el7cp.x86_64
python-cephfs-10.2.10-17.el7cp.x86_64
ceph-selinux-10.2.10-17.el7cp.x86_64
ceph-mon-10.2.10-17.el7cp.x86_64
ceph-common-10.2.10-17.el7cp.x86_64
ceph-radosgw-10.2.10-17.el7cp.x86_64
在更新了 Ceph YUM 源并执行 Upgrade 时，出现错误：
--> Finished Dependency Resolution
Error: Package: 2:ceph-selinux-13.2.5-0.el7.x86_64 (Ceph)
Requires: selinux-policy-base >= 3.13.1-229.el7_6.9
Installed: selinux-policy-targeted-3.13.1-229.el7_6.6.noarch (installed)
selinux-policy-base = 3.13.1-229.el7_6.6
Error: Package: 2:ceph-base-13.2.5-0.el7.x86_64 (Ceph)
Requires: gperftools-libs >= 2.6.1
Installed: gperftools-libs-2.4-8.el7.x86_64 (@rhos-10.0-ceph-2.0-mon-signed)
gperftools-libs = 2.4-8.el7
You could try using --skip-broken to work around the problem
显然是 selinux-policy-base 和 gperftools-libs 的版本依赖不足，解决这个问题的办法有两个：
- 升级操作系统 YUM 源
- 升级这两个 rpm 包
这列我们主要使用第 2 个办法。
升级 RPM 包
Step 1. 下载依赖版本的 RPM 包
[root@overcloud-ovscompute-0 fanguiju]# ll
-rw-r--r--. 1 root root 495060 Feb 2 00:26 selinux-policy-3.13.1-229.el7_6.9.noarch.rpm
-rw-r--r--. 1 root root 7246376 Apr 30 18:46 selinux-policy-targeted-3.13.1-229.el7_6.9.noarch.rpm
Step 2. 执行升级
[root@overcloud-ovscompute-0 fanguiju]# rpm -U selinux-policy-targeted-3.13.1-229.el7_6.9.noarch.rpm
warning: selinux-policy-targeted-3.13.1-229.el7_6.9.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
selinux-policy = 3.13.1-229.el7_6.9 is needed by selinux-policy-targeted-3.13.1-229.el7_6.9.noarch
[root@overcloud-ovscompute-0 fanguiju]# rpm -U selinux-policy-3.13.1-229.el7_6.9.noarch.rpm
warning: selinux-policy-3.13.1-229.el7_6.9.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
selinux-policy = 3.13.1-229.el7_6.6 is needed by (installed) selinux-policy-targeted-3.13.1-229.el7_6.6.noarch
麻烦在于升级 selinux-policy-targeted 首先要升级 selinux-policy，但升级 selinux-policy 又会被低版本的 selinux-policy-targeted 依赖。所以只能先卸载低版本的 selinux-policy-targeted：
yum remove selinux-policy-targeted
然后升级 selinux-policy：
rpm -Uvh selinux-policy-3.13.1-229.el7_6.9.noarch.rpm
最后再安装新版版的 selinux-policy-targeted：
rpm -ivh selinux-policy-targeted-3.13.1-229.el7_6.9.noarch.rpm
Step 3. 查看升级结果：
[root@overcloud-ovscompute-0 fanguiju]# rpm -qa | grep selinux-policy
selinux-policy-3.13.1-229.el7_6.9.noarch
selinux-policy-targeted-3.13.1-229.el7_6.9.noarch
同理在把 gperftools-libs 升级。
- 更新前
[root@overcloud-ovscompute-0 fanguiju]# rpm -qa | grep gperftools-libs
gperftools-libs-2.4-8.el7.x86_64
- 更新后
[root@overcloud-ovscompute-0 fanguiju]# rpm -qa | grep gperftools-libs
gperftools-libs-2.6.1-1.el7.x86_64
再次升级 Ceph。
