i don't think so, these low power procs will work just fine i think.. mine are second powerful in all range, and uses much power - when idle it uses about 100W without any hdd/controllers. at full load it uses over 200W.

I got mine board from ebay (DE) at 200 Eur without CPU/RAM, so your offer is very cheep(may be board are semi-broken ? remember to test.).. mine was with unknown bios password on arrival, so needed to re-flash latest BIOS, and yes flashed on-board SAS 2008 with IT firmware too - works like a charm. i'm not using it with unRAID but in different VM.

when i was on X9SCM-iif with same configuration of disks, the results are pretty the same. so i think it's not CPU related.. i have 4 vCPUs assigned to unRAID VM, and i see, parity check utilize approx one vCPU fully.. what is your CPU usage when doing parity check? and sorry - i have no more hdd's there, so can't test with more added.. one more question - you have 3 M015 - this mean one is working on x4 slot. - how many hdds you have connected to that slot? with 8 hdds using all at once, you will suffer for some bandwith bottleneck..

Yes, i have Raid0 array as parity, but for parity check it should be as fast as the slowest drive. for me it's not parity, but i have three 4TB data drives - all 1TB/platter "green" drives, so it works as expected. Two more messages, just for reference: Total size: 4 TB Elapsed time: 6 hours, 59 minutes Current position: 3,50 TB (87,6 %) Estimated speed: 105,2 MB/sec Estimated finish: 1 hour, 18 minutes Sync errors detected: 0 Parity check finished (0 errors) Description: Duration: 8 hours, 30 minutes, 38 seconds.

I have M1015 cards in my setup too, just started a parity check, after 9 minutes the results are: Total size: 4 TB Elapsed time: 9 minutes Current position: 83,6 GB (2,1 %) Estimated speed: 162,3 MB/sec Estimated finish: 6 hours, 42 minutes Sync errors detected: 0 see all hardware details in my sig below. i'm on unRAID v6B15 - did not upgrade further cos i'm on esxi with USB drops issue with V6 final..

Is there any documentation on how this is done with regard to UPS's attached to unRAID guest VMs? i'm connected my APC unit to Windows VM, but this is similar to unRAID i think. first, i'm telneting to unRAID and power it down with sbin/powerdown then wait some time (1minute for me) and ssh to esxi host and excute "/sbin/shutdown.sh && /sbin/poweroff" look at unRAID /etc/apcupsd/doshutdown you can ssh from here to esxi host and execute command above.. if you have VMWare tools installed on unRAID, esxi will do clean shutdown i think.. (not tried yet..)

ok, i just tested it on my test server (X9SCM-iif board) with 6.1 final and no change for me - issue are still there.. for me, a quickest workaround is to add second USB device - flash or UPS and then no issues..

have you connected more USB devices or this single one? looks something similar to esxi USB dropouts - when i add second USB device to unRAID, no more dropouts to me..

as i read somewhere on the net "error -110" usually means too much power for this USB - USB2 drive plugged in USB3 slot or similar..

Just added iperf to Nerd Tools. Enjoy! i'm just wondering why iPerf, it's very old tool! use iperf3 instead IMHO

Yes, may be but then you have to wait somewhere till the end of the year when more Linux distros(Ubuntu for example) start shipping kernel 4.

so, had some more time for testing today, some new observations: - since i added separate UPS to my test server, i plugged it in usb too, and added both unRAID flash and UPS to my Ubuntu test VM. and surprise, no more usb resets, leaved it for and hour, still no usb resets. then i restarted my Ubuntu VM with unRAID usb flash only and resets are back.. - next i tried unRAID v6 final VM with both usb's - booted and noticed resets started happening. then i setup UPS daemon, and voila, no more usb resets.. leaved it for an hour and half and no single usb reset. Have anyone some comments and/or ideas what to try next?

as i wrote above, my Sundisk USB2 flash works without reset errors for me too.. that's really weird if it's flash manufacturer dependent...

on Ubuntu it should be: cat "/boot/config-`uname -r`" | grep CONFIG_USB_EHCI not sure it's the same for unRAID, cos /boot is your flash drive..

ok, but with those two lines you mention above unRAID v6b15 works just fine.. everything else i should test with this issue? i have no idea...

ok, i spent much time on this issue, and there are my current observations: fo me, it looks like it's flash dependent, cos i have two servers with very similar Lexar flash devices and both of them are resetting. on one server i have some sundisk flash too, and this one don't throw usb resets. my tests are performed on Ubuntu VM's with various kernels, and i paste syslog fragments below from both working and non-working: working one: Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.669283] scsi 3:0:0:0: Direct-Access SanDisk Cruzer Glide 1.26 PQ: 0 ANSI: 5 Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.671284] sd 3:0:0:0: Attached scsi generic sg2 type 0 Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.686596] sd 3:0:0:0: [sdb] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.700103] sd 3:0:0:0: [sdb] Write Protect is off Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.700106] sd 3:0:0:0: [sdb] Mode Sense: 43 00 00 00 Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.712911] sd 3:0:0:0: [sdb] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA Jun 25 14:31:02 i5TestUbuntu kernel: [ 4.959287] sdb: sdb1 Jun 25 14:31:02 i5TestUbuntu kernel: [ 5.037076] sd 3:0:0:0: [sdb] Attached SCSI removable disk nonworking: Jun 25 13:22:46 ubuntu15 kernel: [ 2.884010] scsi 2:0:0:0: Direct-Access Lexar USB Flash Drive 1100 PQ: 0 ANSI: 4 Jun 25 13:22:46 ubuntu15 kernel: [ 2.884299] sd 2:0:0:0: Attached scsi generic sg2 type 0 Jun 25 13:22:46 ubuntu15 kernel: [ 2.900210] sd 2:0:0:0: [sdb] 15659008 512-byte logical blocks: (8.01 GB/7.46 GiB) Jun 25 13:22:46 ubuntu15 kernel: [ 2.909449] sd 2:0:0:0: [sdb] Write Protect is off Jun 25 13:22:46 ubuntu15 kernel: [ 2.909455] sd 2:0:0:0: [sdb] Mode Sense: 43 00 00 00 Jun 25 13:22:46 ubuntu15 kernel: [ 2.918925] sd 2:0:0:0: [sdb] No Caching mode page found Jun 25 13:22:46 ubuntu15 kernel: [ 2.919135] sd 2:0:0:0: [sdb] Assuming drive cache: write through Jun 25 13:22:46 ubuntu15 kernel: [ 2.978855] sdb: sdb1 Jun 25 13:22:46 ubuntu15 kernel: [ 3.015183] sd 2:0:0:0: [sdb] Attached SCSI removable disk i bolded one message above which seem make sense.. may be some of you with better Linux knowledge can comment it out?

ok, thanks for the info.. so you are using reader with flash card(which one? ) and if you have paid licence, then you must transfer your key?

Thanks a lot Dan, much appreciated! Will look into it shortly. Off to search for a microsd card.... I just used the same card reader with a generic microsd (32GB was all I had on hand). 20 minutes in, no more reset messages, whereas I was getting them about 40 seconds after booting, and then every 30 or so seconds. Running esxi 6, passing through the usb device, USB connected to a usb 2.0 port (wire from mobo header). Hi, can you show us a model of the MicroSD card reader?

quoting myself, just for reference: i setup my ubuntu 14.04 VM yesterday, tried various combinations with kernels 3.13, 3.19, 4.04 and all of them sooner or latter had USB errors.. tried Win8 too, worked, Esxi's vmkernel.log has no USB errors.. so, it looks like something weird for me with this..

Hi, i googled this with various combinations with no luck - i just think, there are not much Linux distros with kernel version 4 now.. for example, Ubuntu 15.10 (will arrive on October i think) will be the first Ubuntu release with kernel 4. so, i will try to setup ubuntu 14.04 with kernel 4 and see whats happening..

for me it's USB2. cos X9SCM nor x8DTG have no USB3 ports.. But is the flash drive a USB2 or USB3 flash drive? A USB3 unit will draw more power than a USB2 unit, even if it's used in a USB2 port. i have Sundisk SDCZ50-008G on my test server - i think it's USB2 flash.. sorry, for unRAID i use Lexar JumpDrive TwistTurn - USB flash drive - 8 GB - USB 2.0 - blue

for me it's USB2. cos X9SCM nor x8DTG have no USB3 ports..

BetaQuasi, are your unRAID v6 suffer for this USB glitch too?
