在安装gfs的时候，yum clean all && yum makecache的时候，会报如下错误，后面发现解决方案。就是在yum clean all && yum makecache之前先将gfs的包解压，然后再进行建立，就ok了
yum clean all && yum makecache

Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

One of the configured repositories failed (glfs),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=glfs ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable glfs
or
subscription-manager repos --disable=glfs
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=glfs.skip_if_unavailable=true
failure: repodata/repomd.xml from glfs: [Errno 256] No more mirrors to try.
