Hey everyone. This is probably Unraid 101, so I'm sorry if it's a "go read the wiki" kind of question. But I want to make sure I do this right the first time. Until now, I've been using Unraid with only one 2TB HDD in my array. Today, I added a 1TB NVME disk for cache + VM images (already set up) and a 4TB HDD that I want to use for redundancy. Being that the new drive is larger, I understand it has to be the parity drive. What is the process I should follow here? Currently, both HDDs are assigned to the array, with the new one being empty. Thanks!

Thank you! I'm going to try this immediately after I install some upgrades in my server. Doing a 1TB M.2 cache drive and that's the perfect place to put this raw image file.

That sounds like exactly what I need! Can you post instructions?

Good call. That will at least let me sync the files, so that's a start. But I'd really prefer to keep their files where I keep all my other projects... on the array. I wonder if there's some way to do this.

I'm a graphic designer and I just took on a new client. They use Dropbox to manage their assets. To give me the things I'll need to do work for them, they shared some folders with me via Dropbox. Now, because Dropbox is basically a file-sharing extortion racket, I was forced to register a paid $12/mo account myself just to access the files my client is already paying them to store. Straight up robbery, but whatever, right? Cost of doing business. I can live with that. The real problem is, how do I sync my client's files? My PC is a Windows VM running in Unraid. I keep all my files on the array, with scheduled backup via SpiderOak. Aside from a passed-through SSD used solely for games, my VM doesn't have a physical disk to speak of. Just a disk image with enough space to hold the OS. And that's a problem because Dropbox's desktop client doesn't let you use Samba shares, even if you mount as a network drive. My first instinct was to use a Docker container instead, and give it paths to my array. There are Dropbox docker images available on Dockerhub. I tried this one. But it doesn't work because apparently, Dropbox's latest requirements cause their headless client to reject anything but an EXT4 filesystem. Somehow, it's able to detect that the container path is actually a directory in a BTRFS filesystem. So it throws an error and refuses to sync. Someone did a workaround for the filesystem restriction, but it specifically says "This is an experimental fix not supported by Dropbox. It might cause data loss.” My client will not be pleased with me if my machine corrupts or erases their files. So this really is not an option. I would just download the files from the web browser, but the folders are so large that the Dropbox web interface gives an error when I try it. The hell should I do?

Yikes, just kidding. I ran memtest86 for longer and did indeed get memory errors. Going to try to isolate which module now.

Sure enough, it happened again with no VMs or Dockers running. I ran memtest86+ and got no errors in the memory... Is it definitely hardware? What would cause this?

Any idea what hardware I need to replace if it does?

I believe I've done all the workarounds. And, as I said, the system was stable with uptimes of several months until just recently. Here are the AMD optimizations I did. At least, all the ones I can remember. I should have made a note. BIOS: Global C-States set to DISABLED Power Supply Idle set to TYPICAL SVM set to ENABLE UnRaid: Set rcu_nocbs kernel parameter

Hey everyone. My server had been solid up until recently, when I began experiencing new problems. Most importantly, the web UI stops working after a few days of uptime. Secondarily — and perhaps this is related — it's outputting messages I've never seen before, such as: May 25 17:10:12 ANDRAS4 kernel: Call Trace: May 25 17:10:12 ANDRAS4 kernel: lookup_fast+0x1d2/0x27a May 25 17:10:12 ANDRAS4 kernel: path_openat+0x2b6/0xc07 May 25 17:10:12 ANDRAS4 kernel: ? filename_lookup.part.16+0xa5/0xcc May 25 17:10:12 ANDRAS4 kernel: do_filp_open+0x4c/0xa9 May 25 17:10:12 ANDRAS4 kernel: ? _copy_to_user+0x22/0x28 May 25 17:10:12 ANDRAS4 kernel: do_sys_open+0x132/0x1ce May 25 17:10:12 ANDRAS4 kernel: do_syscall_64+0x57/0xe6 May 25 17:10:12 ANDRAS4 kernel: entry_SYSCALL_64_after_hwframe+0x44/0xa9 May 25 17:10:12 ANDRAS4 kernel: RIP: 0033:0x145931420380 May 25 17:10:12 ANDRAS4 kernel: Code: 25 00 00 41 00 3d 00 00 41 00 74 36 48 8d 05 87 c3 0d 00 8b 00 85 c0 75 5a 89 f2 b8 01 01 00 00 48 89 fe bf 9c ff ff ff 0f 05 <48> 3d 00 f0 ff ff 0f 87 84 00 00 00 48 83 c4 68 5b 5d c3 0f 1f 44 May 25 17:10:12 ANDRAS4 kernel: RSP: 002b:00007ffcdba6f960 EFLAGS: 00000246 ORIG_RAX: 0000000000000101 May 25 17:10:12 ANDRAS4 kernel: RAX: ffffffffffffffda RBX: 0000000000420f23 RCX: 0000145931420380 May 25 17:10:12 ANDRAS4 kernel: RDX: 0000000000000000 RSI: 0000000000664860 RDI: 00000000ffffff9c May 25 17:10:12 ANDRAS4 kernel: RBP: 0000000000628270 R08: 0000000000000000 R09: 00000000ffffffff May 25 17:10:12 ANDRAS4 kernel: R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000008 May 25 17:10:12 ANDRAS4 kernel: R13: 0000000000420f23 R14: 0000000000000000 R15: 00001459314fe4c0 May 25 17:10:12 ANDRAS4 kernel: Modules linked in: dm_mod dax xt_CHECKSUM iptable_mangle ipt_REJECT ebtable_filter ebtables ip6table_filter ip6_tables vhost_net tun vhost tap veth ipt_MASQUERADE iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 iptable_filter ip_tables nf_nat xfs md_mod it87 hwmon_vid igb i2c_algo_bit alx mdio edac_mce_amd kvm_amd kvm crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel pcbc aesni_intel aes_x86_64 crypto_simd cryptd k10temp ahci i2c_piix4 glue_helper i2c_core libahci wmi_bmof mxm_wmi wmi ccp button pcc_cpufreq acpi_cpufreq [last unloaded: i2c_algo_bit] May 25 17:10:12 ANDRAS4 kernel: ---[ end trace 08e156b27250f0bc ]--- May 25 17:10:12 ANDRAS4 kernel: RIP: 0010:__d_lookup_rcu+0x5a/0x12f May 25 17:10:12 ANDRAS4 kernel: Code: 89 ea 41 89 ee d3 ea 48 8d 04 d0 48 8b 18 48 89 e8 48 c1 e8 20 48 89 04 24 48 83 e3 fe 48 85 db 0f 84 c4 00 00 00 4c 8d 6b f8 <44> 8b 63 fc 4c 39 7b 10 0f 85 aa 00 00 00 48 83 7b 08 00 0f 84 9f May 25 17:10:12 ANDRAS4 kernel: RSP: 0018:ffffc90003f13bc0 EFLAGS: 00010282 May 25 17:10:12 ANDRAS4 kernel: RAX: 000000000000000c RBX: ffef88028cd56008 RCX: 000000000000000a May 25 17:10:12 ANDRAS4 kernel: RDX: 000000000006f25d RSI: ffffc90003f13d50 RDI: ffff88028fcc3440 May 25 17:10:12 ANDRAS4 kernel: RBP: 0000000c1bc97651 R08: ffffc90003f13d50 R09: 8e04502e0637f6d7 May 25 17:10:12 ANDRAS4 kernel: R10: ffffc90003f13c2c R11: 8080808080808080 R12: ffffc90003f13c88 May 25 17:10:12 ANDRAS4 kernel: R13: ffef88028cd56000 R14: 000000001bc97651 R15: ffff88028fcc3440 May 25 17:10:12 ANDRAS4 kernel: FS: 00001459314fe540(0000) GS:ffff88082ec40000(0000) knlGS:0000000000000000 May 25 17:10:12 ANDRAS4 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 May 25 17:10:12 ANDRAS4 kernel: CR2: 00000000006ab000 CR3: 0000000282d2e000 CR4: 00000000003406e0 May 25 17:10:27 ANDRAS4 kernel: general protection fault: 0000 [#19] SMP NOPTI May 25 17:10:27 ANDRAS4 kernel: CPU: 0 PID: 13062 Comm: lsof Tainted: G D 4.18.20-unRAID #1 May 25 17:10:27 ANDRAS4 kernel: Hardware name: Gigabyte Technology Co., Ltd.

Nice, thanks for these.

Thanks for the help, everyone. I finally fixed it. All I needed to do was change the IP assignment from static to automatic in network settings. The address is the same either way because the MAC is bound to the IP by the router. Still, it only works when Unraid is set to get the address from DHCP.

Well, I appreciate the effort to help anyway! I set up the bridge by following instructions given to me in this thread. But I didn't purposely create a vlan, nor do I know anything about them. I suspected the bridge might have something to do with the problem, but when I return the network settings to default, the problem still exists.

I did post diagnostics. See post #5.

My unraid UI isn't able to connect to the internet to update, get community apps, etc. I'm trying to fix that, starting with pinging my router. My router is 172.16.1.1 My server is 172.16.1.2 (also tried 172.16.1.18 in case the router was reserving the first IP in the DHCP pool, but it isn't) VM 1 is 172.16.1.3 VM 2 is 172.16.1.4

Bump

Here is the output of diagnostics. Is there any more information I can provide that would help someone assist me? andras4-diagnostics-20190109-2115.zip

Maybe if I manually update the files on my usb device to unraid 6.6.6, that will fix it? Are there dangers associated with this?

Thanks, I didn't know that. I renumbered my network, but the problem persists. It seems that wasn't the source of the issue.

I think something is misconfigured on my server. I can access the Unraid web GUI just fine from any device on my network. And both of my VMs connect to the internet without issue. But the server itself can't connect to the internet or even ping my router. I'm not sure when this happened, because it was working after I updated to 6.6.3. All I've done since then is set up an ethernet bridge between the two NICs so that I could connect a second computer to the network via the server's spare port. But if that is the cause, turning off the bridge and turning on bonding again does not fix it. In fact, when I do that, I can no longer access the server from any device except for the one plugged into the spare port, and it still can't ping the router. I've attached my syslog and a screenshot of my network settings. Any thoughts? Thanks! syslog.txt

I don't get it. You're saying you'd pass the sensor to Windows to read temp, and use the arduino to make up for the sensor's disconnection from the BIOS?

This problem obviously isn't going anywhere. Maybe another solution. Is it possible to pass the temperature sensors to a Windows VM?

Thank you!

My unraid machine has two ethernet ports. I want to use the second one as a bridge to connect a nearby device to my router. Is there a setting I can use in Unraid to do this?
