Issue: When coping a large file (like 8GB) from Win 11 to Unraid 7.0.1 via SMB, Unraid freezes. Windows reports this as the network location being unavailable. The unraid webGUI and all dockers stop responding. The CLI seems to still be running because I can "gracefully" shut down the system by pressing the power button on the case. Rebooting doesnt start a parity check, so I assume its shutting down fine. The system wont recover on its own and must be restarted.

 

Any help or ideas would be greatly appreciated. 

 

Hardware:

AMD 5900x, 64GB DDR5, 2x LSI 9211-8i

 

Things ive tried:

• Error logs dont show anything at the time of the feeze (Apr 3 10:12 AM in the attached diagnostics)
• Ive been able to repeat this about 10 times over the last month. 
• After rebooting the file that was copying is present on unraid, but half the file is corrupt.
• Its freezes up regardless of where the file is being transferred to. Ive tried directly to the array, ive tried using two seperate cache pools.
• The issue started around the time I moved from win 10 to win 11 and also starting messing around with IPv6 on my network. Not sure if these are related.
• SMB Settings: Netbios was originally enabled, but I disabled it. No affect.
• Its not the specific file, ive tried several large files ranging from 8GB to 25GB.
• Ive checked internal connections to the backplane and they all seem to be fine.
• I have moved files as big as 50GB within unraid using the webGUI to move them.

 

Things I havent tried yet:

• Memtest. Could it be a memory Issue
• Copy from another computer.

See if it also happens transferring to a disk share (or exclusive share)

After enabling disk share, the same thing occurs during a large transfer to the disk share.

 

Then, and assuming it happens writing to an array disk and pool, it suggests more a hardware issue to me, but I would recommend retesting with a clean Unraid install, copy just the key, super.dat and the pools folder for the assignments, to rule out any config issue.

Thats not going to be fun. Thanks for the help, itll probably be a while before I can get them time to do a clean install.

 

Updating to 7.1.2 resolved this issue, but my system clearly has other problems. I'm doing a Memtest and then going to do a fresh install of unraid.

Memtest showed over 200 errors within 40min. I have replaced the RAM and done a fresh install of unraid copying just the key, super.dat and pools folder. Thanks again.
