harmon Posted February 25, 2016 Share #1 Posted February 25, 2016 Hi, This is a continuation of some ancient threads: http://xpenology.com/forum/viewtopic.php?f=2&t=4080 http://xpenology.com/forum/viewtopic.php?f=2&t=1848 I like to reopen this topic because, from my point of view, the most relevant limitation using virtualization for runninng XPEnology is the lack of smart monitoring Si, I propose a new solution for SMART monitoring using ESXi. Yes, using Physical-RDMs is possible to read SMART values! So the only problem is enable this funtion in XPEnology. --- First, read these two pages: 1) FlexRAID using ESXi: http://www.flexraid.com/2014/02/07/stor ... m-vs-vmdk/ Go to point #14 and see the proposed solution for read S.M.A.R.T. info using pRDM: "smartctl --device=sat,auto" 2) Manual of SmartMonTools: https://www.smartmontools.org/browser/t ... rtctl.8.in Go to point "-d TYPE, --device=TYPE" and see the reason of use this command: "sat[,auto][,N] - the device type is SCSI to ATA Translation (SAT). This is for ATA disks that have a SCSI to ATA Translation (SAT) Layer (SATL) between the disk and the operating system. SAT defines two ATA PASS THROUGH SCSI commands, one 12 bytes long and the other 16 bytes long. The default is the 16 byte variant which can be overridden with either '-d sat,12' or '-d sat,16'. If '-d sat,auto' is specified, device type SAT (for ATA/SATA disks) is only used if the SCSI INQUIRY data reports a SATL (VENDOR: "ATA "). Otherwise device type SCSI (for SCSI/SAS disks) is used." --- As a proof of concept I do this test on my current XPEnology instance (5.1 running on top of ESXi 5.5 with 4 HD in PHYSICAL RDM)...

If Selective self-test is pending on power-up, resume after 0 minute delay. So, as XPEnology is using smartctl for read smart values, I suggest to include some support for use this tweak when calling to the command or provide some function for tweak (add new parameters) to the call when the user likes to use some virtual environment.
