December 1, 201510 yr Hi all, Upgraded from 6.1.2 to 6.1.4 today through the plugin page. Server was all healthy before hand. After the reboot my cache drive shows as having a smart error on the dashboard, but on the cache drive under identity the drive shows smart overall-health being healthy. smart log download should be attached. what is also odd is that under the self test tab it shows that the drive is spun down (although it is up), no mater what i do i cannot spin it up and so i cannot run a manual self test. Is the drive really faulty or something else afoot? tower-smart-20151201-2147.zip
December 2, 201510 yr It's another rather interesting and novel SMART report. The Marvell developers appear to have followed the gist of the SMART standard, but adapted it for their own purposes, and not according to general practice. The only way the drive fails SMART is if it almost runs out of reserved space. The rest of the thresholds are non-numeric, which is unexpected. They should at least be zero's. Perhaps the unRAID SMART logic is not handling that correctly (bonienl?). The drive looks fine. Because it's an SSD, spin up or down is meaningless, really only changes the current power state. A manual self-test may or may not be supported. The SMART standard does not require it, but so far every drive I've seen before this does support self-testing, although not necessarily the same tests. You will want to add 232 as the custom SMART attribute to monitor, and uncheck 188, 197, and 198, for this drive only. === START OF INFORMATION SECTION === Model Family: Marvell based SanDisk SSDs Device Model: SanDisk SDSSDHP128G Serial Number: 143174403430 LU WWN Device Id: 5 001b44 c61710166 Firmware Version: X2316RL User Capacity: 128,035,676,160 bytes [128 GB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS T13/1699-D revision 6 ...

December 2, 201510 yr Author Thanks for the reply RobJ. As you said the drive looked good i thought id give the server a reboot this morning (didn't when i had the issue incase there was a problem with it and further diags were needed) and the disk reports fine now and the side issue with not being able to run a manual self test has now gone as well. Cheers again RobJ
