Hello, I started my unraid server in 2023. I am going on about 2 years now. I use all Windows PCs or laptops, so I access it through SMB. I feel I have done everything right, however, file read speed is very slow at times. Sometimes, if I want to open up a large file, it takes minutes to load, if it ever does. And then there are other cases where I will be accessing it frequently -- whether that's read, writes, or reorganizing files -- and it just goes offline. The server shows as unreachable through Windows Explorer and the terminal is unreachable through the IP address in the browser. This has happened enough times, but when it does, the diagnostics are wiped before I have a chance. I tried enabling the write diagnostics to flash but it doesn't appear to be there. The server is also just unreasonably slow at times, and while I understand SMB ain't great, I also get slow speeds when transferring directly within something like DoubleCommander. I just see people talk about how nice their UNRAID server is and I know that there is something I'm not getting. I have attached my diagnostics. In these diagnostics, I have a very large amount of reads from the flash drive. About 1,000,000 in an hour and a half. I know this is abnormal and is likely caused by the issue listed in the help documentation, where the OS is being pushed to being read from the flash drive. I know how to fix that, however, I figure now is as good as a time as any to finally maybe see if there is something else going on under the hood. ringo-diagnostics-20251103-0712 anonymized.zip

Old thread, but I finally got around to fixing the issue. I had 11 HDDs and 2 SSDs all chained on 2 SATA rails of my power supply. I suspect it was less to do with the splitters themselves and more the fact that I was just putting way too much demand on each PSU line. I solved this by upgrading to an RM1200x due to its 16 total SATA connectors and rebuilt the array and all is good as new.

Yes, the device shows as disabled, contents emulated. I say that because the reads/writes activity is 0 and I am getting all kinds of warnings regarding the drive. After your post I have looked into UDMA CRC errors (never heard of these before, so thank you for pointing that out) and read that power splitters can often cause this issue, and I believe the drive is connected to a power splitter (but is not the only one connected via a splitter). I will tinker around with it and post here with my results for future people looking for help. Thanks!

Sorry - to my own message preview, I was able to download the files from the links. But upon opening this thread in a private browser, it seems that the files are made available only to me when I'm logged in. Didn't think that'd happen if I did inline embeds. ringo-diagnostics-20241021-1858.zipsyslog-100.67.43.19.zip Try this. Thanks! ringo-diagnostics-20241021-1858.zip syslog-100.67.43.19.zip

Hello, One of my disks has become unreadable recently. My system has double parity so all data is safe. I ran both a short and an extended SMART self-test and both completed without error. This leads me to conclude the drive is safe (these are all Manufacturer Recertified drives from Serverpartdeals, and this one has been running in my system for about a year) but that there is an issue elsewhere. I suspect it could be an issue with the SATA cable (connected to SAS HBA) but I currently have no spares, stores here are closed at the moment, and I don't want to start unplugging working drives and plugging them in to troubleshoot for a cable, as I'm very wary of breaking something that is currently functional. I can test tomorrow but figured I'd post here in case somebody else notices something. I have attached my diagnostics to this post, but since my system was restarted two days ago, there are not many diagnostics, so I've attached the syslog that I set up on August 27th via the Settings --> Syslog Server option. Thanks in advance for any help! syslog-100.67.43.19.zipringo-diagnostics-20241021-1858.zip
