recognize if there is a Software RAID available (otherwise a No RAID available message will appear) monitor the status of a RAID: health of volume(s), failed volume(s), rebuilding volume(s). The custom sensor as described here will be able to. Need help monitoring hardware? Contact us. The present article provides an approach for monitoring a RAID. There are not something to alert on, but could be useful for graphing rather than having to eyeball mdadm -detail, and also to get some of the history of the array. You can configure RAID alerts to bypass the monitoring process by changing the SMTP server and notification email destination in the configuration for a. When you are recovering/resyncing, node_md_blocks and node_md_blocks_synced can tell you how the array getting synced back up is progressing (and if /proc/sys/dev/raid/speed_limit_max may need a tweak). Node_md_state indicates if the array is recovering using a spare, resyncing after an event such as an unclean shutdown, active and healthy, or disabled and inactive. A RAID1 array with only one active disk is not exactly in prime health after all. He says he never imagined that he would ever make such a device, but the war has shifted the paradigm of what is a must, a necessity, or useful. Each platform implementation may be slightly different with different dependencies. RAID BIOS Version: 5.33 / 5.33 (UEFI BIOS) RAID Treiber Version: 5. Depending on how you are managing the RAID, there will be different options available, and with this being an HP system, I would recommend checking with them if you are working with their VROC implementation, as this is customized by each OEM. DC-600e RAID 2-Kanal SATA 6G RAID PCIe 2.0 Controller. Node_md_disks is the primary metric of interest as you will want to know if there are any failed disks, and depending on your the setup you may also know that there must be a minimum number of spares and/or active devices. By using those two components, Dmytro has created an air raid siren monitor that shows which parts of the country are being shelled. RAID Monitor Version: 3.4.4 download: Handbuch als PDF (deutsch) download: Handbuch als PDF (englisch) download: Flyer als PDF download. For one of my home RAID1 arrays the node exporter produces: # HELP node_md_blocks Total number of blocks on device. The Linux software RAID metrics are one of the more intricate metrics in terms of parsing due to /proc/mdstat being more suited to humans than machines, which you can get a sense of from the unittest fixture.
