  1. My connection doesn't go up & down. Once it goes down, it won't come back up unless I reboot the server. The interface shows up on the server but it's not forwarding any network traffic. This was happening for the onboard motherboard NIC as well as the PCIE SFP+ card.
  2. The ipolex transceiver was installed back in early July & is only being used to connect a laptop to the network. I am indeed using a DAC cable to connect my Unraid server to the MikroTik switch. I've had no issues with any connectivity for the laptop & the transceiver. Nor have I had any issues with the Windows machine that is also connected to the same MikroTik switch via DAC cable. As I mentioned previously The Windows machine has the same model Chelsio T520-LL-CR 2-port SFP+ PCIE card as the Unraid server. The MikroTik switch isn't showing any errors for any interfaces or connections that may have indirectly affected the Unraid server's connection. Also I checked to make sure that the ipolex transceiver was compatible with the MikroTik switch before I purchased & installed it. I only mentioned the ipolex transceiver just to be thorough in describing my network environment. I highly doubt the ipolex transceiver is playing ANY part in the connectivity issues I've been experiencing with my Unraid server's network connection. Fortunately I haven't experienced any drops since my last post on 9/4, but as I mentioned previously there was about a two week period that I didn't experiencing drops before I suddenly started experiencing frequent drops again. I will continue to monitor & update this thread if I start experiencing drops again in the near future.
  3. @jonp Since setting the PCIE card's 10GBe interfaces to eth0 & eth1 and disabling the bonding group for eth0 after my last post on 7/29, I didn't experience any drops for almost two weeks. During that time period I continued adding HDDs to my UnRAID array without any issues. On 8/10 or 8/11 I added a M.2 NVME to PCIE adapter card along with a 2TB NVME SSD. On 8/13 I experienced another drop and had to reboot the server to restore connectivity. I went almost another two weeks before experiencing another drop on 8/24. Since then I've began experiencing drops more frequently again, occurring roughly every 1 or 2 days & in one case dropping less than 20 minutes after having just rebooted due to a previous drop on 8/29. Below is a list of times & dates that I received loss of connectivity alerts from software I have running on a VM running within the server: Aug 13, 3:54 PM Aug 24, 8:54 AM Aug 27, 2:42 AM Aug 29, 8:47 AM Aug 29, 12:18 PM (Server was only online for about 20 min after previous reboot) Aug 31, 12:36 PM Sep 1, 6:55 AM Sep 3, 2:00 AM Sep 4, 3:07 AM I've attached diagnostic files that I pulled after each drop listed above, while the network connection was still down before I rebooted the server. I may have pulled the 8/13 diagnostic file after I had rebooted. Your help is appreciated in helping me try to identify the root cause of these network connection drops. unraidsvr-diagnostics-20200904-1051.zip unraidsvr-diagnostics-20200903-1120.zip unraidsvr-diagnostics-20200901-0920.zip unraidsvr-diagnostics-20200831-1237.zip unraidsvr-diagnostics-20200829-1239.zip unraidsvr-diagnostics-20200829-1157.zip unraidsvr-diagnostics-20200827-1008.zip unraidsvr-diagnostics-20200824-1007.zip unraidsvr-diagnostics-20200813-1621.zip
  4. So I tried removing eth0 & eth1 from the bonding group but obviously you can't remove eth0 if the bonding group is configured on eth0. So I tried moving the static IP configuration to eth2 with no bonding group, but for some reason I couldn't configure DNS for any interface other than eth0. The UnRAID server apps & dockers were unable to resolve URLs with this configuration. I ran into some issues trying to revert back to the original eth0 network configuration & completely lost network access to the server. After spending a couple hours late last night troubleshooting trying to re-establish network connectivity I was able to get things working again by deleting the network config file on the USB flash drive & letting UnRAID auto regenerate the network config file during boot with a DHCP configuration & then reapplying my original static IP address on eth0 with the other interfaces included in the bonding group. I noticed after the network config file was regenerated by UnRAID interfaces eth1, eth2, & eth3 looked different on the network setting page. Before they just said unconfigured, but now it says they are part of a bonding group & to see eth0. I thought maybe an issue with the previous network config may have been the cause of the previous network disconnects. I was tired at this point & didn't want to continue tinkering with the network settings last night, so I left the config as is & started another large file transfer to run over night. The next morning the network connection dropped out again at around 8:51am this morning (Diagnostic file attached). This time I modified the network-rules config file so that the 10Gbe interfaces on the PCIE card were now eth0 & eth1 and the motherboard NICs are now eth2 & Eth3. I was then able to disable the bonding group for eth0. We'll see if removing the bonding group makes a difference. unraidsvr-diagnostics-20200729-1008.zip
  5. I did replace my NetApp X2065A-R6 Controller with an LSI 9200-8e controller on 7/23 per a recommendation due to multiple drive errors & missing disks after a reboot or shutdown. Here is the thread topic I started concerning that issue: That seemed to resolve the disk errors & missing disks issue so far. I can't say for sure if the network disconnects only started after the controller was replaced, but I believe it had occurred at least once before the controller was replaced. It has definitely become more frequent in the last few days since the controller was replaced with disconnects occurring at least once a day now. Other than that I've been continuously adding drives to my array, but I've been doing that since I first setup my UnRAID server. I started by converting the Windows OS running on the server into a VM. Then installed UnRAID on the server & passed through the SATA controllers on the motherboard to the Windows VM. I would then transfer data from the disks connected to the motherboard to disks in my UnRAID array which were installed in a NetApp DS4246 shelf. I would then move the empty disk to the disk shelf & add it to my array. I've been repeating this process starting with three 16TB drives (1 for the data array & 2 for parity) and have moved 7 disks from the motherboard to the disk shelf & array so far. I did notice that the disconnects seem to occur during large & long data transfers that had been running for several hours, but I've been almost constantly transferring data from the local motherboard disks to the UnRAID array since I've got my UnRAID server up & running with almost 100TB transferred & counting, So that might just be due to the fact that I'm usually transferring data than not. I've started large data transfers to run over night in the past without any issues. Also the data transfer between the VM & array don't appear to traverse the NIC as the transfers continue even after the network connectivity drops out. I often wait for the transfers to complete before I reboot the server. I did add a QNAP QNA-UC5G1T USB 5GbE adapter to a laptop on my network back on 7/8. Connected via a Cat6 cable, I plugged an ipolex 10G SFP+ RJ45 Copper Transceiver into the same MikroTik switch as the UnRAID server. I've had no connectivity issues with the laptop or the other Windows machine with the same Chelsio NIC that is connected to that switch. I've had two more disconnects since my original post occurring on 7/27 at 6:46am & again this morning 7/28 at 4:46am. The 7/27 disconnect occurred during a large file transfer from the Windows VM that I had started the previous night that was still running after the disconnect. The 7/28 disconnect this morning occurred after a file transfer that I started the previous night had completed maybe about hour prior to the latest disconnect. I've attached the diagnostic file I grabbed after the 7/27 disconnect. I've probably provided a lot of information that may or may not be useful but I just wanted to provide any & all information that maybe helpful in helping me diagnose this issue. I will try disabling eth0 and eth1 in the bonding group as you recommended. I currently have another large file transfer running that should finish in the next 2-3 hours. I will disable those interfaces once the transfer is complete. unraidsvr-diagnostics-20200727-1420.zip
  6. I've had my new UnRAID server running for about a month now, but in the last few days the network connection to my server suddenly disconnects and I have no network connectivity. Internal communication between the server & the VM I have running on it works fine, but the VM cannot communicate with the rest of the network either. The only thing that resolves the issue is rebooting the server. The connection will be fine for a couple or more days & then drop out again. It is a 10Gb connection to a Chelsio T520-LL-CR 2-port SFP+ PCIE card I installed. That is connected via a 5-meter 10G Twinax cable to a MikroTik CRS305-1G-4S switch. I have a Windows machine with the same Chelsio card connected to the MikroTik switch as well & haven't had any issues. I tried disconnecting & reconnecting the cable, using another cable, using the other port on the Chelsio card, using a different interface on the MikroTik switch. My motherboard is an ASUS Z10PE-D8 WS with dual Gigabit Ethernet interfaces which I don't use, but since the server is configured to bond all interfaces in active-backup mode, I tried connecting to the motherboard's Ethernet interfaces & neither of those got the connection to come back up even though the server logs listed the following: Jul 26 15:43:32 UnRAIDSVR kernel: igb 0000:09:00.0 eth1: igb: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Jul 26 15:43:32 UnRAIDSVR kernel: bond0: link status definitely up for interface eth1, 1000 Mbps full duplex Jul 26 16:07:58 UnRAIDSVR kernel: igb 0000:09:00.0 eth1: igb: eth1 NIC Link is Down Jul 26 16:07:58 UnRAIDSVR kernel: bond0: link status definitely down for interface eth1, disabling it Jul 26 16:08:04 UnRAIDSVR kernel: igb 0000:08:00.0 eth0: igb: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Jul 26 16:08:05 UnRAIDSVR kernel: bond0: link status definitely up for interface eth0, 1000 Mbps full duplex The 10Gb interfaces are eth2 & eth3 on my server. I've attached the diagnostics from the server. The most recent network connection drop occurred around 2:17 PM today. Any help would be appreciated. Thanks unraidsvr-diagnostics-20200726-1704.zip
  7. Thanks. I've ordered the LSI card & cable for it. I'll Let you know if that resolves the issue once they arrive & I get them setup.
  8. So you think the card is causing the errors? Would you recommend I replace it with this card: LSI 9200-8e 6Gbps 8-lane external SAS HBA P20 IT Mode https://www.ebay.com/itm/LSI-9200-8e-6Gbps-8-lane-external-SAS-HBA-P20-IT-Mode-ZFS-FreeNAS-unRAID-NoROM/163534822734?epid=28034148027&hash=item26136f5d4e:g:5sEAAOSwdwlcX2E3
  9. As far as digging into the inner workings of the disk shelf is beyond my expertise or comfort zone. Do you see something in the diagnostic logs that would indicate the drives are disconnecting or losing power? I've never had an issue where a drive is missing while the array is running. It's only occurred right after boot up. Once a drive is recognized they are stable until a shutdown or reboot.
  10. The shelf has dual power supplies & are plugged into a UPS.
  11. I've setup a new Unraid server that I've been running for a few weeks now. I've been in the process of migrating my data & HDDs from a Windows machine to my Unraid array. I would transfer the files from an HDD to my Unraid array then preclear the empty drive before adding it to the array. I've been repeating this process until all of my drives will be added to the arrray. I've added 9 drives so far, but 4 drives have been disabled due to errors during data transfer. Two of the drives that have been disabled are brand new Toshiba MG08ACA16TE 16TB drives that were successfully precleared with pre & post reads. The other two are drives that had been running fine on my Windows machine for a while. It's hard for me to believe that I have 4 bad drives. The array drives are in a NetApp DS4246 shelf with a NetApp X2065A-R6 Controller that I bought both used. I'm concerned if maybe the shelf or controller are the root cause of the errors. I've attached diagnostics from the last two occurrence of errors. In one instance two drives had errors at the same time. One was a Parity drive. My other issue I'm not sure if it's related or not, but after a shutdown or reboot different drives would be missing after booting back up. It seemed random because a different drive or two would be missing each time. At first I would keep rebooting until all the drives came up, but as I added more drives to my array at least 1 or 2 drives would be missing. Soon I discovered that if I removed a drive for about 30 seconds then reconnected it in it's slot, UnRAID would recognize the drive. Once again I wonder if this is an issue with the shelf or controller. Thanks for any help unraidsvr-diagnostics-20200714-1614.zip unraidsvr-diagnostics-20200717-1511.zip
  12. I did just that & ran the preclear again skipping the pre-read & got the same error. I then moved the 3rd drive & put it in the slot that one of first two drives successfully completed in, to make sure there wasn't a hardware issue with one of the slots in the disk array shelf. I then ran preclear for a third time, still the same result. I've attached the latest logs. First Two drives finished successfully & I currently have them running in my array with one as a parity disk. Also one weird thing I noticed is that every time Zeroing gets to 50% on the drive I'm having issues with, the speed goes up to 1200+ MB/s. How is that possible on a HDD with a SATA3 interface? Does that indicate some kind of issue with the drive? Thanks for any help. Preclear Log 20-06-29.txt
  13. Setting up my first Unraid server. I bought 3 new Toshiba MG08ACA16TE 16TB drives. All three are in a NetApp DS4246 shelf. I Intend to use two of them as parity drives. I started a preclear on the 1st drive a little after midnight on 6/23. I started a preclear on the other two drives later that day around 5pm. The 1st drive is currently about 59% into the Post-Read phase and one of the other two drives is 48% into the Zeroing phase. Preclear on the third drive suddenly stopped with a message on the main page that says "Preclear in progress... unRAID's signature on the MBR failed - Aborted" Does this mean the drive failed & is bad? Or is there some other issue? I've attached the preclear log from my server Preclear Log.txt
  14. Temporarily moved cache drives to usb docking stations until I can free up more internal SATA ports. Cache Pool is working again. Thanks!
  15. I am new to unraid & currently building my first setup. I have a pair of 1TB SSD drives for my cache poole with currently about 262GB used & 738GB free so far. I installed SSD Trim & scheduled it to run nightly at 1am. After the 1st run last night my VM stopped working and I am unable to open or write files in the cache pool. Fix Common Problems found the following errors: Unable to write to cache - Drive mounted read-only or completely full Unable to write to Docker Image - Docker Image either full or corrupted When I try to run my VM I get the following error message: Hook script execution failed: internal error: Child process (LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ /etc/libvirt/hooks/qemu BitTorrentVM prepare begin -) unexpected exit status 126: libvirt: error : cannot execute binary /etc/libvirt/hooks/qemu: Input/output error If I try to edit the VM I get the following error message: VM creation error cannot create file '/etc/libvirt/qemu/BitTorrentVM.xml.new': Read-only file system I tried to run a btrfs scrub but nothing happens and the scrub status is immediately aborted I've attached my diagnostic file unraidsvr-diagnostics-20200623-1037.zip
