looked at your board's manual, all seems correct, this slots is x16 electrically.. you can try second PCIe slot too, just for testing..

To answer your question, yes, I would want virtualization. However, admittedly, at the moment I know not a thing about it and so much so I wouldn't have thought that hardware made a difference other than maybe processing power. I just don't want to close any doors for myself. When I built the server I have now I thought a Sempron CPU was all the power I would need since the hard drives or the network might be the bottleneck for transferring files. Along comes PLEX and ruins that for me. So I'll be installing a CPU that can transcode PLEX well. then SUPERMICRO MBD-X10SL7 you mentioned before will be very good choice in combo with Xeon Processor..

Need more info about motherboard and PCIe slot you use with SM card.. are there another PCIe cards used? if yes, then which slots?

It depends first question to answer - what will be typical usage: NAS only or some sort of virtualization too?

if PCIe slot operate at x8 electrically then no speed difference compared to mobo SATA ports with 8 HDD on that card..

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..

if you plan run this PC headless then IMPI is a must have IMHO it's very useful too when you are away from PC location for a long time, like me when i'm at my summer house for all summer ..

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...

Hi, just my 2c i'm not seeing everyone about what RAID we are talking about: real-time on snapshot OK, according to Tom's first post, RAID6 is a real-time one, but unRAID currently implements both variants - writing to disk share is real-time, to cached user share it's more snapshot if you don't have a cache pool.. so, if you think in terms of snapshot where mover runs once(or twice..) a day, and all disks are up, then you must have an option to define more than dual parity - SnapRAID have maximum of six now.. BTW, have anyone tried combine unRAID with SnapRAID for additional parity? with VMs it's possible now i think... EDIT: thanks Trurl, corrected

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?

I have not considered that, but thanks for the idea. That being said, there isn't much cost difference between moving to a 24-bay case, and building a new 15-bay server, and I would still would get more expansion with the 15-bay server.. The only savings may be in power consumption. consumption of power and room for new server for me room is a problem cos i have no basement for my lab.. for now another option to expand more is to add second case with power supply only and then use expansion card from first server. if these two cases are close, that's an option and would use much less power compared with two full servers..

Steven, have you measured an option for large case but two or more unRAID servers as VMs? i'm always wondered about these huge unRAID arrays with just a single parity.. you can create two arrays and new unassigned drives plugin join them together.. mine server have two small arrays, ok, one unRAID and second with Snapraid over Ubuntu VM - more or less for learning

Plex was my first docker, when i started use docker at all so i think, just look at guide and all should go fine.. and i think you just need to copy your old plex config to new place after you setup your plex docker, and then all config should survive.

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?

Yes, those messages are on unRAID syslog - and keep repeating every 30 secs.. Quoted again myself - i can see those messages in vmkernel.log too.. 2015-06-17T13:17:23.385Z cpu2:41053)<6>usb 2-1.1: device is available for passthrough 2015-06-17T13:17:23.469Z cpu2:41053)<6>usb 2-1.1: reset high speed USB device number 3 using ehci_hcd 2015-06-17T13:17:23.591Z cpu6:41053)<6>usb 2-1.1: Device is allocated for USB passthrough use; not available for VMkernel use 2015-06-17T13:17:23.591Z cpu6:33149)<6>hub 2-1:1.0: resumed 2015-06-17T13:17:23.591Z cpu6:33149)<6>hub 2-1:1.0: suspended 2015-06-17T13:17:23.790Z cpu6:41053)<6>usb 2-1.1: reset high speed USB device number 3 using ehci_hcd

Hi, just upgraded plugin to latest version, smb mounts look promising but how about NFS? for me NFS between unRAID and Ubuntu workstation works approx twice as fast as SMB mounts.. if we use this to share files between two unRAID servers, then NFS works much faster i think..

Yes, those messages are on unRAID syslog - and keep repeating every 30 secs..

No, i think i will wait for some time to v6 final or more with production server upgrade, not decided jet i can setup test server with x9SCM-iif, but this will happen in the middle of the next week maybe, i'm not at my lab now.. but i'm sure, you can find v6b15 install(on limetech git? ) and give it a try.. Uldis ok, today i assembled back my test server with x9SCM-iif. esxi6 with unRAID 6b15 are working ok, then upgrade to unRAID V6 final and full syslog with similar messages as OP. and unRAID then is so unresponsive.. so i'm staying on b15 for a while....
