this sounds like the exact issue i have! havent looked at your diag but are you on 7.1.4?

Hey All, unfortanetly i couldnt get many logs as i needed the get the system back online, but i just want to raise a possible bug. Running all the services of unraid(Docker, VMs, file shares) have a decent size pool I cant boot to unraid GUI version. it throws a "Kernal Panic: VFS cannot open root device" i searched the forums and it suggested to replace all the bz* files on the usb which i did. I tried to use the GUI boot version again as i didnt know why it crashed. Still couldn't boot using GUI rebooted and just selected normal boot(CLI) and it booted. if i can get any logs out after the case happy to forward, but thought i would raise maybe the GUI boot is broken. Also still dont know why it crashed. all back online happy Symptoms of crash: Lost access to GUI Lost access to SMB shares Docker and VMs still running ssh still working Noticed 1 Windows 11 vm maxing most cores(htop) used virsh to stop VM CPU stablaised to like 7% all other docker and vms working SMB and GUI still not working tried to stop several docker containers via ssh(just to be safe) but they failed to stop with i/o error from memory issued a reboot via SSH and it just said system shutting down. Waited 15 mins and got nothing logged into idrac and hard powered Its a Dell R750 fully patched. Also i went from V6 to V7 very quickly a week before or so. But the server has been stable for years

LEGEND!!! thank you so much!!!!

Hi All, struggling with an issue. My array is telling me i have 10TB free but i can not move anything onto array as i get No Space Left on Device. Cache is fine, but cant do anything with the array. Have attached my diag. mattaverse-diagnostics-20240701-2032.zip

same issue here.. seems like a dns issue with plex.tv added 99.80.18.66 plex.tv to /etc/hosts in the docker container

everything was fine. turned out to be unraid not linking the full 1TB mem. have just enabled the first slot on each CPU will diagnose in the future. Thanks your your help!

Thanks for the reply Vr2Io but i just worked it out.. kinda i disabled 14 of the 16 dim slots via bios and its now freaking fast! Its a beast of a server brand new Dell R750, dual 6330, 1Tb memory, 10 x 1.92tb NVME, 2 x 9400-16e talking to 12 x 16tb, 8 x 10tb can work with 128gb mem for the moment, just been without for 2 weeks so keen to get everything set back up! once online ill then start playing with the memory config as i think its a server issue.. while dell shipped the server with all memory populated in the first 8 dimms and dell can "optimised" thats not the actual channel config.. ill change the memory into the channel groups when i get back home in a couple of weeks.. idrac has been so handy while building haha

Hi All, still trying to diagnose my speed issues with a Dell R750 dual Gold CPU 1Tb memory NVME, etc tested alot and my final test i think i have gotten to is a fresh reboot and not start the array. I have then done a dd test to the ramdisk and i would have expected better speeds? Writing to the 18 disk array i get about 10-15MB and reading i get 20-30MB Installed windows server 2022 as a test and speeds are fine can max out the 10GB nics...

parity runs normal, but everything is so slow even the gui. Dockers are painfully slow. Only started after a reboot which took 20-30 mins to mount the array and then instantly received the btrfs cache disk error. have nothing installed on the cache and just navigating unraid is slow.

mattaverse-diagnostics-20221028-2024.zip fresh reboot and mount then logs collected

just removed all plugins, ill reboot and then do a fresh grab and upload.

HI Team, Been a long time user of unraid and currently on my 4th generation Dell R750 dual Gold 6330 1TB ram 10 x 1.92Tb SSD on the internal raid marked as non raid disks(using as cache 4 drives as cache, other 6 not mapped currently) 2 x 9400 HBA connected to 12 x 16Tb, 5 x 10Tb, 1 x 8Tb dual 16Tb parity 1 x dell M2 PCI-e 480Gb in mirror for downloads pool The issue im now randomly having and not sure why is it takes almost 20 mins to start the array. all drives are encrypted ct 27 06:31:56 HOSTNAME*** emhttpd: shcmd (203): udevadm settle Oct 27 06:31:56 HOSTNAME*** emhttpd: Opening encrypted volumes...
