Dave-Kay Posted July 22, 2019 Share Posted July 22, 2019 (edited) Hello, I am using unraid for a bunch of years now and i am still delighted how good it works for me. So i suggested to a friend to use unraid, too. He bought hardware an began setting it up an ended up in a ton of problems, till i decided to take his hardware to my home and to start testing it. At first everything was good. i set up the system and began testing, disk, docker, vm all good. But then i added an ecrypted disk. immediately after everything was set up and i began to copy files on the encrypted disk, the system stopped responding. the copyprocess stopped, my explorer on the windowsmachine stopped working and i was unable to stop the array. I tried xfs encrypted, as well as btrfs encrypted. At the moment the system is clearing a disk again for the next try. i tried to find clues, about what i possibly could have done wrong, but i didn't find anything which would have been an explanation for the behaviour. what am i missing? what do i have to search for? Version is 6.7.2. As i said, the sytem ran just fine, till i tried to use encrypted disks. thanks in advance for your help Edited July 28, 2019 by Dave-Kay Quote Link to comment
Dave-Kay Posted July 23, 2019 Author Share Posted July 23, 2019 (edited) So i tried again, and ist seems to be failing again. hardware is ASRock C3758D4I-4L 32GB Memory 2x WD-Red 4TB 1 x WDC_WD20EZRX At the moment it seems to be endles syncing drives to stop array. 2 out of 8 cpus are at 100% I'm stuck with this. tower-syslog-20190723-1549.zip Edited July 23, 2019 by Dave-Kay Quote Link to comment
Dave-Kay Posted July 23, 2019 Author Share Posted July 23, 2019 So i had to hard reset the server because he wouldn't neither finish the sync, nor tell me what is going on in any way. after next boot this appeared out of nowhere. (see image) Quote Link to comment
Dave-Kay Posted July 23, 2019 Author Share Posted July 23, 2019 (edited) So it seems, there is nothing really written to the encrypted drive. As i said, i had to hard reset the server, as he told me, he was syncing the filesystem. after next boot i accessed the share and it was empty. i have never seen anything like that before. (of course there is no cache drive.) Edited July 23, 2019 by Dave-Kay Quote Link to comment
Dave-Kay Posted July 23, 2019 Author Share Posted July 23, 2019 found something interesting though... both modules show like this in dynamix System Information Memory Device Total Width:8 bits <<<<<<!!!

Dave-Kay Posted July 24, 2019 Author Share Posted July 24, 2019 as i wasn't able to pull diagnostic after the appearing Problems, i pulled one after systemstart now. Memtest didn't find anything tower-diagnostics-20190724-1504.zip Quote Link to comment
testdasi Posted July 24, 2019 Share Posted July 24, 2019 You might want to troubleshoot each variable one by one. Start with - does your array work WITHOUT encryption? 1 Quote Link to comment
Dave-Kay Posted July 24, 2019 Author Share Posted July 24, 2019 (edited) Thank you for your reply! 10 minutes ago, testdasi said: You might want to troubleshoot each variable one by one. Start with - does your array work WITHOUT encryption? Yes! After the friend failed to get it working and i suspected the encryption the first approach was of course to just test the system on this Hardware, without any encryption. I installed it and put plugins in it, VMs and Docker-instances. Everthing worked just fine, for 2 days. After that i wanted to add encryption and immediatels the sytem had gone nuts as described.

testdasi Posted July 24, 2019 Share Posted July 24, 2019 That's what I suspected. Encryption needs quite a bit of oomph on the CPU and I think yours is an Atom which may not be powerful enough. I have seen a lot of posts about hanging / slow performance with encryption and the consistent theme throughout is low-power CPU. 1 Quote Link to comment
Dave-Kay Posted July 24, 2019 Author Share Posted July 24, 2019 Oh, i didn't find anything here in the forum. But i didn't even consider performance-Problems in any way. So there shoulkd be Problems with any linux and luks on the machine, too? Quote Link to comment

Dave-Kay Posted July 26, 2019 Author Share Posted July 26, 2019 (edited) It's just the same, if i try to copy the files in MC. That's highly disappointing. Edited July 26, 2019 by Dave-Kay Quote Link to comment
JorgeB Posted July 26, 2019 Share Posted July 26, 2019 Sounds like some specific issue with that hardware and encrypton, but I never used encryption so not very familiar with it. Quote Link to comment

Yeah, thats what i think. but i really don't know which Hardware... however, next step, changing RAM. Quote Link to comment

You're right. That didn't help. I had 6.7.3.rc1 installed for testing, which didn't change anything. Now i downgraded to 6.6.7 and i am waiting for parity ceck once again...

Dave-Kay Posted July 28, 2019 Author Share Posted July 28, 2019 6.6.7 didn't work either. I'm lost. Quote Link to comment

If so, then a CPU upgrade is in order. 1 Quote Link to comment
limetech Posted July 31, 2019 Share Posted July 31, 2019 We include a lowly Atom D510 @ 1.66GHz for all testing and writing to encrypted volumes works just fine - perhaps a bit slower but certainly no hangs or time-outs. 1 Quote Link to comment
jbartlett Posted July 31, 2019 Share Posted July 31, 2019 I'm wondering if it has something to do with cross-drive shares. You have Drive 2 excluded in several of the shares. Which drive are you encrypting? I'm assuming that you're copying to the encrypted drive. Have you tried copying to an unencrypted drive? Have a telnet session open to "Tower" with "tail -f /var/log/syslog" running before you start to copy. Quote Link to comment
