Thanks for the info, itimpi. So maybe I'll need to look at switching over to 6.4 sooner rather than later. I haven't followed the development on 6.4, so I need to see where it is in the process. Thanks again!

I'm using version 6.3.5 and the Web GUI keeps crashing, but everything running on the server still works perfectly fine (I can access all the shares, VMs, and Dockers), I just can't access the unRAID GUI. I have another thread about the crashes, but in the mean time, I was wondering, is there any way to restart the GUI when it has crashed? I've searched and haven't found anything on it, so I was hoping posting the question would tell me for certain whether or not it is possible. Any insight you can give is greatly appreciated. Thanks!

So I let Memtest run for 30 passes (basically for 3 days) and it found zero errors. I restarted my server (running yet ANOTHER parity check) and it has been up for 2 days, but has crashed again. I was trying to start a Windows 7 VM when the GUI stopped working. Just like always, everything in the background is still running, but the web GUI is non-operational. I have run the diagnostics again and attached them. Thanks for any help you can give. On another note, as I'm running 1 to 2 parity checks a week because unRAID is being so unstable, I'm just curious if I need to start worrying about burning up drives? I have 15 drives in the system, most of which are WD Enterprise drives, so they should be pretty tough, but they are all a bit old (I moved them from a previous Windows machine where they were set up in a large raid 5). Thanks again. epcot-diagnostics-20180116-2212.zip

Thanks, Johnnie! I'll try that and see what I get.

Over the last few weeks I've been having a problem with the Web GUI crashing and not allowing me to do anything, but my dockers are still running (I can access my VPN, Minecraft Server, all the shares, and can SSH into the machine, etc.). I haven't been able to find a way to restart the GUI or to shut the system down gracefully through SSH, so I've been having to hard reboot the server every few days, which has lead to a crazy number of parity checks, so I'm afraid I'm going to start having drives fail. These crashes always seem to happen when I'm doing something mundane on the server. Today I tried to do a soft reboot from the UI (as the last 5 or 6 times the server was booted up was from these lockups and me having to hard reboot it), and I got the reboot message in my browser, but the server never came back online. I'm only a novice with Linux, so I've tried to understand the log file, but I'm not seeing anything that tells me what the issue may be. So with this, I have three questions...First, is there a way to restart the Web GUI through SSH if it crashes? If not, is there a way to gracefully shut down the system via SSH? And lastly, can someone with more knowledge than myself please take a look at the attached diagnostics file and tell me if there is something there I can change to make the server more stable? Thanks for any help you all can give. Cheers. epcot-diagnostics-20180112-0037.zip

Is it normal for this to lock up the web GUI when the backup is running? I started it about an hour ago and since then, I can't access my server via the GUI, but I can SSH into it and when running htop I see that it is pinning the CPU usage at 100 (though only on a single core). I can still access my shares from other systems, and my dockers are still working (my MineOS server and OpenVPN are still running anyway), but I can't access the GUI. Was just wondering if anyone else has experienced this issue? I'm going to let the backup run overnight and check back on the server tomorrow. Thanks for any input you guys can give. EDIT: This has now been running for 14 hours and continues to peg the CPU at 100% load and I am still unable to access the unRAID GUI. Still wondering if this is normal? Should I let it continue or should I hard reboot the server (as I've tried killing the process and can't seem to kill it)?

I was able to resolve my issue. If you have bonding enabled to allow multiple NICs to work together, you have to set Key1 to "bond0" (or whatever the connection name is). After doing this, I was able to get into the GUI w/ no issues.

Hey all, I'm trying to set up OpenVPN on my unRAID server, I'm following the video from Spaceinvader One (here), but when I try to open the WebUI I get the page below (The site cannot be reached) and I'm hoping you guys can help me out. Sorry, I'm very new to unRAID and I've never used any type of VPN except what I use for work. Any help would be greatly appreciated. Thanks.

Here is the text from the file or you can look at the file itself, as it is attached as well. Thanks for your help, Squid!! Edit: Removed syslog text in code box (I thought it would put a set size box, not lengthen the thread to the size of the code). Sorry about that. syslog.txt

Squid, thanks for the info. Below is the info before the Call Trace. How would I know which drive to check?

Thanks, tdallen, that is good info. Very helpful! I'll try to look into passing a user share into the VM because very large disk sizes are something that I need to have. The current backup file for one of my systems is sitting at 4.2TB and right now I'm running a RAID 5 on the i5 machine which allows me to have 1 "drive" that is about 10TB (only 6 of my drives are currently being used). Edit: So I'm trying to find out how to do this, but while I'm looking, I guess I should make sure having a user share larger than any single disk in the "array" is possible, i.e. what I was stating above?

So I'm about 5 days into my 30 trial run with unRaid and I'm really finding it fascinating and hoping to switch my home server to it if I can figure out a few keys things... First, my current home "server" is just an old i5-3570k (not currently overclocked) system, 4-core/4-threads, 16GB RAM. I'm wondering if this will be enough to run a Plex server (in a docker as I understand, but I haven't investigated this yet)and 1 Windows 7 VM that is only used for video transcoding and backing up other systems? I don't really care too much about speed, I usually set the transcoding to run at night, but I don't want it to take days. Right now (using it as just a straight Win7 system), it takes about 45 minutes to transcode each hour of video, which is fine. If not, I do have a small budget for an upgrade in hardware, but nothing too crazy. Second, I tried last night to create a disk that was larger than my largest hard drive to be passed to the Win7 VM, but when I started the VM, the drive didn't show up? Is it possible to create a virtual disk that is larger than the largest physical hard drive (i.e. I have 10x2TB Hard drives (2 parity, 8 storage) and I want to create one 5TB drive on the Win7 VM, is this possible?). I'm sure I'll have more questions as I continue to play with unRaid, but these are the ones that are vexing me now. Thanks for any help you can give!!
