Evening all, Everything has been working without any issues for over a week and a half without powertop with auto tune being run. Thanks for your assistance.

The disk2 rebuild without issue and doesn't look to be have reported any further issues (diag attached). I did notice after running through the old diags that the ata error on the 582 controller was reported 5 seconds after running the powertop script (log section below). I've stopped the powertop autotune not run on this boot. Could this be an issue with the controllers/drives not working well with powertop? Vr2lo: The input voltage to both the laptop and the M2-ATX is 19V from the same PSU. Power usage measured at the mains as per the graph below, (Disk 2 rebuild finishing at the start of the graph, Mostly idle the 2nd half) The issues also seem to have happened when the disks were already spinning which I think counters the too little power and also too much power draw. I'll add a meter to monitor the output of the M2-ATX 12v line to see if it dips. My current thinking is to leave it to settle for 3-5 days and see if any errors show up, if all clear I might run powertop and see if anything changes. I know powertop has options to exclude devices from it's tuning. tower-diagnostics-20221227-1443.zip

Hi itimpi. I believe you might be confusing it with the JMB575 which is the multiplier. I've attached the datasheet for the 585. I did check the forums ahead of selecting the controller. JMB585.pdf

Thanks for your reply. I moved the drive that dropped to the other controller with a fresh sata cable late last night and started the rebuild process, it's about 50% so far. I'll post new diag's when I'm back home. Where/what in the diag's point you to the errors? I'd love to know what I'm looking for. Would you know if there's any known compatibility issues with the JMB controllers and drives? Are the errors showing for all drives or just the WD? The controllers are JMB582 and JMB585.

Good Afternoon (and happy xmas!) I'm having issues with my Unraid setup after changing to new hardware. My previous setup ran without issue but I'm re-scaling the hardware to reduce power usage. Everything was tested pre migration as my backup server (5 HDD and 1 SSD) without issue for over a month including full data copy between the servers and multiple parity checks. I moved the main server USB and disks to the hardware and started having issues within 2 days, 1 of the drives (10TB) kept dropping from the array without warning, I replaced the sata cable, redone the power to remove all splitters and ended up moving the drive to another controller. Nothing resolved the issue on the drive (which rebuilt every time and then dropped within 2 days). I replaced the drive in the end and done a parity swap. Fast forward to a week later and the old parity drive which is now in the same disk slot 2 (from an Unraid perspective) has just done the same. It's using the same sata/power cables/controller it's had from the initial move and has showed no issues until now. As an FYI the hardware is a laptop using M.2 sata adaptors, the PSU running the drives is an M2-ATX 160W the total power usage at the time of the failure was under 60w with a 130W power brick running both the laptop and PSU. Can anyone shed some light and point me in the right direction? Log below and diagnostic's attached. Many thanks in advance to anyone who can assist. tower-diagnostics-20221225-1407.zip

Thank you for your reply, I'll update it as soon as the array is rebuilt. I have loaded in the cold spare 8tb drive and it's rebuilding now, about 24 hours at a guess by which time the new parity 10tb drive should have arrived and i can look at the firmware and preclear the new drive. On a positive note the drive that has failed smart (Parity) looks to be within warranty.

Good Afternoon I done some work on my network the weekend and moved the server (very carefully), after getting everything fired back up everything was good and working. Before bed i started a parity check (about 16 hours to complete) and woke up to a ton of emails reporting issues on 4 drives (8 in the array), these drives are all on the same controller (and the only drives on the controller). These errors started with the parity drive (Time: 00:48), Disk 3 (Time: 00:50), Disk 2 (Time: 02:12) and Disk 1 (Time: 03:06). My thoughts so far, 1 - cable issue 2 - drive failed causing the controller to "glitch" 3 - 4x failed drives Post reboot i have one disk disabled by unraid (Disk 3) and another showing pre-failure smart issues (Parity) but the array is up. I have attached the smart reports and diagnostics (pre-reboot). I'm going to replace both drives, i have a spare which i'm going to replace drive 3 tonight and tomorrow i have a 10tb arriving to replace the parity. Can anyone advise on the drives that are showing errors or as to what caused the issue? Best course of action? Thanks to anyone who can advise ST8000DM004-2CX188_WCT00M8N-20200511-1157(Parity).txt ST4000DM000-2AE166_ZDH0JCWB-20200511-1327(Disk 3).txt tower-diagnostics-20200511-0822.zip

Well i'm not a Homeassistant guy, Openhab here (As i know at least one other Unraid user is). I was looking at doing some of this over ssh, but this works alot better from a home automation standpoint in general. Thanks for making it. As it is it works better for openHab, if your going to change it it might be worth giving the option ether way? I had a quick look and adding load values, cpu/memory usage would be nice (if its not in there and i didn't see it).

Good Afternoon, hope your all having/had a good weekend. My current server is now coming to end of life (well, getting over stretched!). It's a i7 3770, 32Gb ram and it's just not cutting it running the normal rack of docker containers with 3 VM (1 Gaming for the misses). Friday i cracked and ordered a Supermicro X9DRH-7TF off of ebay with 2x E5-2603 (£250), the processors are going to be too slow, but my though is it gets me up and running while not adding much cost. I can soon update them in a month or two with something with more meat to it. The board lists supporting non-ecc ram (not recommended i know) but i accept that i might have to order more. Down to the brass tacks, i'm running Unraid 6.7.2, all my drives are on a LSI SAS2008 card (connected to a SAS expander), networking is currently handled by a dedicated card. Any recommendations on the best way to proceed? I have twin unraid pro licenses (1 i'm not using atm) so my thought was to backup (plus screen shots) the config to the other unraid drive and move the hardware across to the new setup. Thanks for any help in advance.

It seems your set firmly on the base, it comes back as clean. Mostly i use windows, but looking at it the command make more sense now. Which leaves me with more trouble shooting more to do.

Hello All Having a "small" storage issue i just upgraded my parity drive which i have done before with no problems, this time as soon as the array came online the web interface stopped working and the array would not online (flash share still worked tho). I have tracked the issue down to the plugins starting up, but the plugins themselves are all fine it seems to be the SSD that i use for storing them outside of the array i think. The SSD is 3 months old and formated with EXT4 outside the array to handle my downloads and plugin storage. My setup is a ESXI box running Unraid pro 5.0 setup as per the "ATLAS" thread on this forum. I have a IBM ServeRAID M1015 sas controller running all 8 channels into an Intel RES2SV240 sas expander. The unraid os has 4 cores of an I7-4770 (3.4Ghz) and 16GB Memory. Total number of drives in the system 9. Im at the final stages of rebuilding parity to the new 4TB drive (ST4000DM000-1F2168) i have no other 4tb drives in the system and all the other drives have spun down as its building past there capacity, but my rebuild speed is only 60MB/Sec at this stage which i would expect to be alot faster. Now whats this got to do with a faulty ssd your thinking? Well the activity light is always on for the bay the ssd is in (which now i think about it has always been on), which i think might be causing the slow rebuild? I have tried to run FSCK on the ssd and get the following: The logs dont seem to show anything i can find but ill attach them anyway. Any help or ideas anyone has would be gratefully received, i know its not strictly an unraid problem. Many thanks - Rick syslog-20141113-154600.zip

Not exactly the correct place for the question, but is there a list of controllers supported at the moment? I checked the wiki and it seemed very out of date. I was looking at http://www.lsi.com/downloads/Public/MegaRAID%20SAS/MegaRAID%20SAS%208408E/MR_SAS_8408E_PB-Final.pdf Unraid compatible? and tho its not listed im guessing it will take 3tb drives?

Your correct in that these are pci-x cards, tho they are in normal pci slots which i knew would limit them to a point. During the rebuild its accessing all 4 drives at once which i knew would cause a hold up. But i would have thought once the rebuild is done and its running under normal conditions (90% read only) that it should be alot faster unless being written to (unless i get a cache drive?). Could somebody recommend a card which does not cost the earth? i have pci-e slots free to use. Rick

Ok i have it. Its one of those things that wakes you up at 3am and you just have to work on! First of all i thought it might be my removable caddys, so out came the hard drives and they for plugged direct into the controllers and the rebuild was restarted. No change, rebuilding at sub 1 Mbps and errors in the logs. In my sleep state i had a crawl through the syslogs and noticed that the same ports (ata1 and ata3) were listed as resetting time and time again. Then it hit me, with 6 ports (3 per controller card) with cables in, and 4 hard drives, what would the chances be of plugging the same drives into the same cables be when i removed the caddys. I checked the first logs and the current ones for which drives were plugged into ata1 and ata3, different drives from before BUT the same errors and also the only 2 drives plugged into that card. A quick re-cable later and this morning after less sleep then i would have liked: Total size: 2 TB Current position: 276.38 GB (14%) Estimated speed: 19.53 MB/sec Estimated finish: 1471 minutes Its not the 40+mb/Sec that itimpi suggested but its alot better and in line with what what i was getting on my old server. Once i have full rebuild i might have to look at what might be slowing it down. The only hardware recycled from the old server in this case were the removable drive caddys, thumbdrive (unraid) and the drives. The case, motherboard, some memory and psu (XFX 750W gaming psu) were from my old "main" pc. With new hardware being some memory, cpu (i7-3770) and hard drive controller cards (Adaptec 1420SA x2) I include the current syslog for 2 reasons, first so somebody with more experience in these things can confirm the issue is resolved and second if you can see anywhere in them that the performance is being limited. Thank you all for your help. syslog.zip

I hadn't thought of somebody not having heard of the magic smoke. (http://en.wikipedia.org/wiki/Magic_smoke) I did ponder trying to fix it with the magic smoke kit but nobody had stock! (https://www.sparkfun.com/products/retired/10622). All joking aside, the failed drive was about 18 months old and i couldn't locate a replacement controller from our stock (i work in a computer store). I have attached the syslog, the current rebuild rate is: Total size: 2 TB Current position: 7.47 GB (0%) Estimated speed: 1.2 MB/sec Estimated finish: 27783 minutes Thanks Rick syslog.zip

Sorry for the lack of a syslog, the system is at home and im at work. Yes i did have smoke from the server. I checked the hard drives and have found a very burnt looking chip on its controller board. This drive is dead. Over lunch i went home and switched out the drive i was rebuilding onto with another new one which seems to have done the trick. The array is rebuilding, but at less then 2MB/Sec. I dont have the full syslog here but its full of the below errors: Aug 20 15:53:52 Tower kernel: ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Aug 20 15:53:52 Tower kernel: ata3.00: configured for UDMA/33 Aug 20 15:53:52 Tower kernel: ata3: EH complete Aug 20 15:54:26 Tower kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Aug 20 15:54:26 Tower kernel: ata1.00: failed command: WRITE DMA EXT Aug 20 15:54:26 Tower kernel: ata1.00: cmd 35/00:00:c7:5c:37/00:04:00:00:00/e0 tag 0 dma 524288 out Aug 20 15:54:26 Tower kernel: res 40/00:01:01:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) Aug 20 15:54:26 Tower kernel: ata1.00: status: { DRDY } Aug 20 15:54:26 Tower kernel: ata1: hard resetting link All the drives are sata 2 (3 Gbps) and the controller cards are Adaptec 1420SA. bad cables or drive caddys? Hope this helps clear it up. Rick

I have now moved over to the new hardware after some issues. The upgrade from 4.5 to 4.7 went well and had no issues for the testing week. The upgrade from 4.7 to 5 tho was problematic. After upgrading the files as per the guide i still had a no access over the network to the unraid. Further investigation pointed to the network card not being loaded. Test booted the thumb drive on the new system and all was fine, until i moved the drives. But thats for another post http://lime-technology.com/forum/index.php?topic=28990.0

Hi, I have just upgraded my software and hardware at the same time (http://lime-technology.com/forum/index.php?topic=28716). After issues with the new unraid not liking my old network card i have now moved to the new hardware. I checked the thumb drive booted and could see the controllers ect and all was fine until i moved the disks over to the new system. 3 (parity, disk 2 and 3) out of the 4 disks moved without issue, the 4th (disk 1)decided to let out the magic smoke and burned a hole in a chip on the pcb. Not an issue i thought as the array was still seen fine just missing one disk. Replacement disk in and started the rebuild which stopped within 30 seconds with errors (128 of them) on disks 1 and 2. Disk 2 is running seatools hard drive diag as i type but no errors as yet. Any ideas or pointers?

Thanks for your reply That was the one i was trying to avoid, the new array is to use some of the older drives. Currently the nas stands at 5Tb (2Tb cache drive), the new one is starting off with a 3Tb cache drive. If i wanted to avoid option 3 totaly im guessing that i can upgrade from 4.5 -> 4.7 -> 5? I have no plugins at all.

Hi all. I'm running Server plus V4.5 currently and the time has come to upgrade the system as im running low on space. At the same time im planning on moving my unraid to an esxi box (as per Johnm's Atlas post) which i have up and running with the newest V5 RC. Is it possible to 1: move the current setup (4.5) to the new system and then upgrade 2: would i be better to upgrade the current box and then move it over to the new hardware 3: the painful way which is to build a new array from scratch and x'fer the data. Many thanks to anyone that can help. Rick

They look like nice board and i know the power load on them is low. I like to build to what i might need, i like the idea of being able to max it out.

I looked around for a duel core atom board with enough slots but have not been ablt to find one. Hane you got a model number of link? I think you will fine the Supermicro 8 Port SATA 2 Card (PCI/PCI-X) AOC-SAT2-MV8 works with unraid, i have seen people using it on the "pimp your rig" post

Asus P5G41-M is the board im thinking about using

Hi, Thanks for your reply. Yes one of my main goals is for power, with performance being a very close second. Im looking to be able to got the full 22 sata ports as i get extra drives, I know by using pci its going to be a bottleneck but i dont think it will be a problem as the most im going to need is for media playback (feel free to correct me if im wrong). The motherboard in question has 1x PCIXx16 slot, 1x PCIX x1 and 2 PCI slots. I plan on getting a 8 port ssata PCIX card, two PCI 4 port cards on the pci bus, and a 2 port sata card on the PCIXx1 slot. This would give me a total of 22 ports. The parity and cache drives being on the onboard ports. The caddys i already have and i was lucky enough for them to have cost me nothing as they were going to be put in the bin where i work. Rick

This is nice, looking at this i might have to have a rethink 1x Asus AT3GC-1 mini-ITX, Motherboard, Atom 330 CPU On Board £ 66 1x PCI RAID 5 Controller SATA 2 II 300 SiI3124 £ 50 4x SerialATA Backplate NA910C 5x SATA DEVICE - 1x Multiplier-x5 port (eSATA) SiI3726 £225 Throw in the ram, cables and drives of choice you have a setup that can take 22 SATA drives with Gigabit LAN, duel core 1.6Ghz cpu and not be loading up the elec bill! Use the 20x ports for data drives and the 2 onboard for cache/parity.
