Unraid 6.7.2 WebUI glitching, unable to access shares

[Dakota]

I am having issues with Unraid 6.7.2 Glitching out. This has been happening about every 2 days. When this happens the unraid webui says "Array Undefined" and shows no drives, not even the boot usb. lsblk still shows all of my storage devices.

The webui won't let me reboot, or download diagnostics. I have community applications, rclone, and user scripts installed as well as a plex docker.

Possibly the Flash has disappeared. Put it in your PC and let it checkdisk.  While there make a backup. 

 

Make sure to use a USB 2 port for booting from Flash.

Thanks for the suggestion. I ran chkdsk on the boot drive and it found no errors. I booted unraid again and about an hour into a parity check it glitched again. I ssh'd in and was able to access files both in the /boot directory, and in /mnt/disk1

Since you didn't mention it, I have to ask. Did you

The next time you reboot and before it glitches, go to Tools - Diagnostics and attach the complete diagnostics zip file to your NEXT post.

And turn on mirror to flash drive in Settings - Syslog Server  After it glitches, post the syslog file stored on the flash drive (logs folder)
