Over 8Tbyte DiskSpace cant get correct TotalSpace

[candlerb]

Is there a delay in the public svn repo on svn.cacti.net? It's over 8 hours since your post and I don't see the change in either branches/0.8.7 or branches/main

Not sure if there is something broken. Would have to check.

I see it now. Thank you.

Just wanted to inform everyone that this issue is back in the Cacti v1.x code.

Total diskspace will only go up to 8 TB, even after applying the patched ss_host_disk.php.

Opened Issue #824 - https://github.com/Cacti/cacti/issues/824

In this case Issue #824 was unable to be fixed by the original patch. The issue is with the RFC for NetSNMP Host Resources Mib, and the specific agent. In the case of the agent, it reports the data as 32bit signed integers in two parts. There is the size or usage, and the storage allocation units, that when multiplied together provide the total number. To prevent overflows of the Net-SNMP INTEGER data (total/usage), the agent must report a false Storage Allocation Unit, and in this case the agent was not doing so. There is nothing Cacti can do to fix that.

This issue must be fixed in NetSNMP, and if there is a Specification Nazi there, they won't approve the workaround.

The custom user script found here works - https://docs.cacti.net/usertemplate:dat ... disk_usage

Yes, this is correct. That is an SNMP agent extension, so it's not a standard MIB.
