  1. @limetech Not wanting to dogpile on to you, but you would do well to go above and beyond in rectifying the situation with any communality developers that have issues. The community plugins and features that supply so much usability and functionality to unraid that are lacking in the base product actually make unraid worth paying for. if you start loosing community support, you will start to loose it all. with that I am sure I and others will not recommend people to purchase and use your software. @CHBMB @aptalca @linuxserver.io Maybe a cool down period is needed, but don't just pack up your things and go home, it's all too common for companies to ignore users and communities, a large part of the community is often invisible to them hidden behind keeping the business running and profits. it makes it easy for customer facing employees to make statements that might be taken as insensitive.
  2. The m.2 adapter is pci-e gen3x2 sata controller, not a port multiplier. JMicron makes ok chipsets, this adapter is likely fine, how well it holds up with time/heat would be interesting to see.
  3. I have a similar connection issue with my ups and get that error as well. It only works for me when the ups is plugged in from the start of a full cold boot. Warm reboots will get that error.
  4. I'll second the odroid N2 option. I have every sbc you can think of and the N2 is one of my favs, it's a great board. decently powerful, decent io, supports emmc. I did grab two pi4's though, it's a good upgrade finally for the pi scene, but as mentioned you need good cooling, check out the pi4 flirc case as a sleek looking passive heatsink case, it's quite good.
  5. Nice you got your issue solved at least. It would have been nice if trim solved the issue for me, i tried it early in the process of debug a few different ways and it just delays the problem slightly.
  6. Removed two files; Syslog had more private info in it since I have some more verbose debugging messages enabled. Lsof; had some Network connections and ip addresses that need not be public.
  7. Fast is subjective, the speeds of the drive are decent for the price and provide speeds faster then the platter drives. If i had the money i would have truly fast nvme drives. but that's not here nor there. No disrespect but please have something constructive when replying in this thread please. As requested above the debug logs are attached. i did remove a few files containing sensitive info found. tower-diagnostics-20190801-0115.zip
  8. The performance of the ssd's are not really in question, they are cheaper sata ssd drives, yes, but still way faster then any spinning disk media, especially for simple workloads like a sequential write. The system should not crumble and become unresponsive with large writes, as stated above this did not happen previously.
  9. I already looked at the smart data for the drives and other then the vendor unique smart data tables, things such as reallocated sectors and the media wear out indicator tables look to be fine, the drives are actually quite new upgrades from smaller drives; with about 3.4 months of power on hours. Even with a trim on the drive with it near empty (the most optimal state for writes on the drive) the issue is still seen albeit takes a short bit longer to appear, this is mentioned in above posts. I hate having to take the system down over and over again but i plan to pull the drives and test them individually for failure time permitting.
  10. I have tested with the cache drive at normal levels of use 60% full and tested with the cache drive at near empty around 60gb. with and without trim, and still see the issue. (post trim the issue will still happen but takes longer to appear as the drives written blocks are taken up.) happy to answer any questions, and i will get the zip file posted tonight. Note: I work in the storage industry, R&D of solid state drives. I have a good bit experience with this area, just don't know how/why this issue has appeared in unraid all of a sudden.
  11. True, and transfers to the array directly seem to be fine. But the entire point of 10Gbe is to reduce bottlenecks of 1Gbe with multiple users and allow for the quick offload of large files to the cache so it can move the large files at its leisure. Working with or moving files at near native ssd speeds is a featured goal. (And looked to work well/fine for about two weeks) You wont "question the wisdom of caching" after transferring +32gb files over 10Gbe to ssd's vs 1Gbe on spinning disks. 😂
  12. Hello. Started to get an issue similar in scope to the issues users were having here, more specifically the issue i am having started with large writes to the cache drive started to slow down to a crawl or near stop and cause dockers and vm's to become unresponsive (the unraid ui often still works) Everything was working fine for a week or two after one of the last changes i made being the addition/upgrade of 10Gbe. large transfers were fast and fantastic and well worth the upgrade but now things slow to a crawl then dockers and the vm's will freeze or possibly crash while the cache disk(s) attempt to write the large data. iowait crawls up to a very large value of like 70% as reported by netdata/top. The 10Gbe change does not seem to be at fault since even transfers limited at 1Gbe will still cause the issue albeit not as fast. Debug steps i have attempted so far with no positive results: Checked logs, Nothing outstanding seen in relation to drive read/write errors or health issues seen Converted from the original cache drive setup: brtfs raid 1 to single drive XFS Checked Ethernet cables Checked Sata cables Attempted to run trim on drives History: Upgraded from 6.6.6 to 6.7.2 shortly after release; had no issues Two weeks ago, Upgraded to 10Gbe, no issues until now. Hardware setup: Intel i7 4790k Asus Z97M-PLUS 32GB Ram LSI 9211-8i (Latest IT-Mode firmware, used with array drives) 1x Parity drive 4x Drives in array 1x unassigned random 512gb ssd for scratch use and other vm's (originally) 2x Sandisk SSD Plus 1TB's in brtfs raid1 for cache (now) 1x Sandisk SSD Plus 1TB XFS for cache 10Gbe Aquantia AQtion 10G Pro NIC, (AQN-107) Any help would be highly appreciated, i will try to post the debug data when i can tonight. Its very odd and confusing how everything was working fine up until now and for things to go bad with no outward changes or visible errors. and i'd like to go back to using a parity backed cache if possible.
