It was found in ledmon 0.74-1 that functionality on Dell SSD devices broke.
The Dell PCIE SSDs do not have a 'hostN' field in their sysfs paths as they are block devices directly connected to their host PCI device.
A patch has been applied upstream and went into ledmon 0.75 to address the issue:
http://ledmon.git.sourceforge.net/git/gitweb.cgi?p=ledmon/ledmon;a=commitdiff;h=d6b7c55869fa7a5224844407ef2d5aab785c4db8 |
[Impact]
* The ledmon version included in Raring contained a bug that broke PCIe SSD devices
on Dell Server Hardware. The Dell PCIE SSDs do not have a 'hostN' field in their sysfs paths as they are block devices directly connected to their host PCI device.
* The bug caused these devices to stop being recognized properly in the OS.
[Test Case]
* Install ledmon 0.74-1 onto a raring server with the appropriate PCIE SSD hardware.
* run 'sudo ledmon' to start the led monitor.
* Look in /var/log/syslog..you'll see messages such as the following repeated continuously several times as the OS tries to figure out what the SSD device is:
ledmon[2449]: Device (null) : No host_id!
ledmon[2449]: DETACHED DEV '(null)' in failed state
* With the upstream patch in place and after restarting ledmon, the "no host_id" and "DETACHED_DEV" messages will go away and the PCIe SSD devices are detected correctly.
[Regression Potential]
* Low. This fix is very targeted to the PCIE SSD hardware on Dell systems, and should not break any other devices.
* Tested by me on the specific hardware to ensure that the regression has gone away.
[Other Info]
