[Starlingx-discuss] Cengn Mirror server in down?!

The jenkins in the cengn build is offline while we repair the file 
system on the mirror.  The build machine both read from, and writes to 
the mirror, and I don't want it to cause further corruptions while the 
mirror is being repaired.

The cengn mirror has been cut over to the new storage back end.  However 
any corrupt files from the old storage back end will remain corrupted on 
the new one.

Restoration of rpm repos will proceed in several phases:

1) An audit of all rpm repos is underway.  Rpm's that fail their 
checksum are being removed and repodata will be updated to reflect the 
missing RPMS.

2) The mirror update job (downloading rpms from upstream rpm repos) will 
be run to restore as many missing files as possible. Many rpms may no 
longer be available as we kept old versions of packages that upstream 
drops when a new version is available,

3) If rpms that are not available from upstream, but are required for 
our build, we can attempt to restore them from one of several places.   
e.g. the inputs directory of various builds, or the downloads directory 
on the cengn build server (independent storage from the mirror)

4) Resume building new loads



All of the release iso's on cengn were corrupt.


I've been able to restore 4.0.1 and 2.0.1 from the original build artifacts.


Original build artifacts for 3.0.0 are missing.  I do have build 
artifacts for builds that were intended to lead up to a 3.0.1 release.  
If a verifiable copy of 3.0.0 can't be found, we may want to consider 
issuing a 3.0.1.  Alternatively I can rebuild 3.0.0, but the file 
checksums wont match the original build due to embedded timestamps.
