badi95 Posted July 30, 2021 Share Posted July 30, 2021 Came back from dropping kids off at school to find my array in bad shape. One disk disabled with 34 errors, another disk with 2048 errors, but still running. I've got Dell T110ii with a LSI SAS 9207-8i connected to 4 2.5" drives (2 SSD, 2 10k HDD) and an Intel AXX6DRV3GEXP with 4 3.5" sas drives, and 4 3.5" SATA drives connected to MOBO. Pre-cleared all the disks when I got them. Attached diagnostics. The system was in heavy use when the errors occurred (transferring TBs of data from hdd cache to array). Could I be overloading the 305w power supply that came with it? nasofbadi-diagnostics-20210730-0913.zip Quote Link to comment

Jul 30 07:44:48 nasofbadi kernel: sd 7:0:6:0: Power-on or device reset occurred This happened to both basically at the same time, it's usually a connection/power problem, start by checking if those two disks have anything in common, other than the controller.

badi95 Posted July 30, 2021 Author Share Posted July 30, 2021 (edited) Those 2 disks are on the same half of the Intel AXX6DRV3GEXP, so I think they share the same power and HBA line. The connectors seemed to be good. The wiring to the Intel AXX6DRV3GEXP is pretty janky though. I have a SATA power splitter to a 1 to 2 sata to molex adapter, plugged into the back of the Intel AXX6DRV3GEXP. Edited July 30, 2021 by badi95 Quote Link to comment
JorgeB Posted July 30, 2021 Share Posted July 30, 2021 You should replace/swap cables and rebuild the disabled disk on top, as long as the emulated disk is mounting and contents look correct. Quote Link to comment
badi95 Posted July 30, 2021 Author Share Posted July 30, 2021 Thanks for the help! I'll search around for steps on how to do the rebuild. Do you think my 305w power supply is sufficient or does it need to be upgraded to handle all the disks I'm running on it? Quote Link to comment

Depends on the quality of the PSU. Wattage doesn't tell nearly the whole story. If you are talking normal consumer grade power supplies, I would be very worried about even a 500W rated unit with 8 3.5 drives and 4 2.5 drives. Quote Link to comment
badi95 Posted July 30, 2021 Author Share Posted July 30, 2021 It's the one that came with my Dell T110ii back in 2012... Suggestions for what I should get? Quote Link to comment
badi95 Posted July 30, 2021 Author Share Posted July 30, 2021 I have virtually know idea what I'm doing when it comes to specing out a power supply. Is this a good option for my situation? https://www.amazon.com/gp/product/B0797CDK7J?tag=serverbuilds-20&geniuslink=true Quote Link to comment
JorgeB Posted July 30, 2021 Share Posted July 30, 2021 That's fine, just make sure the current PSU is standard ATX, many Dell computers use a custom PSU. Quote Link to comment
trurl Posted July 30, 2021 Share Posted July 30, 2021 Be sure you only use the cables that come with modular supplies because there is no standard pinout. People have fried disks by trying to reuse modular cables from another supply. Quote Link to comment

Begin by measuring the physical size of the PS and see if it is a standard size. Some OEM manufacturers use non-standard components to lock you in to using replacement parts from them! Second, you are looking for a PS with a single +12V rail. (Unless, you plan on installing a serious GPU card into your server, there is no need for a second rail.) Look for a manufacturer with a known reputation for building a quality supply. Allow approximately +2.5 amps per HD for the surge when the drives spins up. (Unraid has several sets of situations when it will spin up all of the drives at once. Be aware that Specmanship is the name of the name in PS wattage ratings. (Usually the total wattage rating for +12V buss will be greater than 95% of the Total PS wattage rating. Basically nothing left to run the CPU and MB!!!) Buy for the future-- Does your case have room for more HD? Do you see a need to be adding additional drives in the future? Quote Link to comment
badi95 Posted July 30, 2021 Author Share Posted July 30, 2021 Ended up picking this up, https://www.amazon.com/gp/product/B0797CDK7J?tag=serverbuilds-20&geniuslink=true and getting 2x sata to molex cables, instead of 1 sata to 2 molex for the intel enclosure. Seems like a good deal for a good PSU. Should I just leave my server running with the disk emulated until I can get everything installed? Quote Link to comment
