Hi guys ,
i changed the HDD of my librenms server to SSD yesterday. i copy all the folder /opt/librenms and did a backup of the librenms.sql , reimported all into the new OS. i went through the configuration again, till the part of the creation of the database , since i had it. also i copied on /opt the previous folder.
OS is Centos 7.8.2003 64bit

====================================

[OK] Composer Version: 1.10.13

[OK] Database connection successful
[OK] Database schema correct

but graphs are empty , eventhough i copied them on the same location and change the permissions to librenms user

any ideas?
thanks in advance

Why didn’t you dd or rsync the whole system?

i did not think about, further more the new drive i set needed a filesystem and an OS on top so rsync wouldn’t have changed the thing.
the librenms folder under /opt/ was copied with rsync
but under re-installation i think did not matched again , the only way to fix it was to delete the entire librenms that i had coppied over, (i kept only the database.sql) but the rrds were lost in the process.
