Hi I discovered some disq was missing fiew days after. I putted in attached the result of the 2 commands I run when I had this issue. discovery.php -v -d -m ucd-diskio -h Hostname >> /tmp/ucd-diskio1 I resolved my issue doing this mv /opt/librenms/rrd/HOSTNAME /opt/librenms/rrd/HOSTNAME.old after this I could see the graph again. Now everything is ok, but here the result of a discovery.php -h HOSTNAME -d |
|
Hi I put in attached the result of the command ./discovery.php -h HOSTNAME -d it misses the disk from sdb to sdu |
|
Can't see anything wrong with the discovery which is probably due to it being fixed. |
|
The discovery is OK, but 2 disks are still missing in the interface (Disk I/O graph). |
|
Please update your install and then provide the info from http://docs.librenms.org/Support/FAQ/#what-information-do-you-need-to-add-a-new-os |

Update done. In the poller file, it's the mess for the sdX Array part. [RRD Disabled]sdh Array Here the info from the messsage log of the server, just to show you multipath removed/add the device but no switch was done regarding the sdX and mapping device : messages: multipathd: sdh: remove path (uevent) messages : multipathd: sdl [8:176]: path removed from map mpathk |

Please provide the output of |

MariaDB [librenms]> SELECT * FROM ucd_diskio WHERE device_id= 69\G; |
|
Your storage index has changed, want to try a patch? |
|
Yes of course, let's try a patch. |
|
I put the patch, run discovery command, but it's still the same. I put new poller, discovery in attanched. |
|
Can you re-run the sql query as that data must now have changed. |
|
No change MariaDB [librenms]> SELECT * FROM ucd_diskio WHERE device_id= 69\G; |
|
I 'v check the patch and replace a coma with a "AND" in the mysql select, I think there is a mistake. Now, the discovery added missing devices but some clean need to be done. Now I have duplicate row with the same diskio_descr. I can have 2 row for the same diskio_descr. MariaDB [librenms]> SELECT * FROM ucd_diskio WHERE device_id= 69 and diskio_descr ="sdl"\G; |
|
Hi I modified ucd-diskio.inc.php to remove duplicate diskio_descr. |

Hello
On a Dell PowerEdge R730 with redhat 6, I have several disk attached to the server through multipathd.
After added the server in librenms, I see all disk (sdXX) in the Disk I/O graph part. Everything is OK.
We disabled and reenabled a fiber channel card on the server for a maintenance.
When we disable the fiber channel, the multipathdd process automatically disable the corresponding path.
On linux each path correspond to a disk device /dev/sdXX.
When we reenable the fiber channel, the multipath, reenable the path and the disk have exactly the same name /dev/sd..
After this action, the device that was disable/enable by multipath are missing in librenms in the part Healt, Disk I/O graph,
The usage of /data/librenms/discovery.php script didn't help.
Here the information of my librenms installation :
