DVD Repository - going crazy

[stevesdl]

DVD repository - sometimes it finally works\ sometimes it doesn't ???
Centos 7.4; Virtualbox 5.2 (7.4 minimal iso; also tried with 7.4 dvd iso in virtual DVD)
(I do not have any issues with http repo)
I have moved all repo files to /tmp/repos

Using su - here are my steps:
mkdir -p /repos/local

cd /etc/yum.repos.d
vi local.repo
[local]
name=The Local DVD
baseurl=file:///repos/local
enabled=1
gpgcheck=0

vi /etc/fstab
UUID=2017-09-06-10-51-00-00 /repos/local iso9660 ro,user,auto 0 0
(I have also used --> UUID=2017-09-06-10-51-00-00 /repos/local iso9660 defaults,loop 0 0) --> also with the word "defaults"

mount -a (no errors but I rarely get the "read only notification)
yum clean all && yum repolist --> all good
df -h shows mounted with correct info.

Its a crap shoot, depending on continuous bumping and removal and retry an install might work but 90% of the toime I get the following:

[root@aserver1 ~]# yum install tree
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
No package tree available.
Error: Nothing to do

I cannot figure it out after hours of googling and trial and error.
Help!!

Why are you doing all that? All that's required is to attach the iso to the VM then mount it on one of the directories listed in the CentOS provided /etc/yum.repos.d/CentOS-Media.repo file (or edit that file and add your own directory to the list). Then run yum --disablerepo=\* --enablerepo=c7-media update (or whatever yum operation you want instead of update). If you want this as a permanent set up then edit the repo files and change enabled=1 to 0 to disable the supplied repos and enable the c7-media repo.

You will need to use the full DVD for anything other than the minimal packages (about 200+ of them) as the iso doesn't contain much. Depending on how esoteric the packages you want are, you may even need to use the 8GB "Everything" DVD iso image.

Always appreciate your quick responses

It was this --> use the 8GB "Everything" DVD iso image.
Somehow when I did continuous testing, the cache was not getting cleared and even though I was using minimal iso, I am thinking the cache was maybe pointing to the 8 gb iso files? that is the only thing I can think of.

thank you
