Unraid 6.2.4

This issue seems to have cropped up since 6.2, but I can't be sure because I rarely copy from my server.

 

I can copy files to my unraid server, but if I try to copy files from the server,  unraid seems to partially crash.  The crash seems to be random, if I try to copy 20 GB, I may get 1GB, 10GB or even all of it before the shares disappear. 

I can also stream video from it with no problem for days on end between crashes with the same symptoms.

 

I am copying to/from a Win10 machine.

 

I can copy hundreds of GBs TO the server with absolutely zero issues.  I have NEVER had this crash happen when copying to unraid.

 

The symptoms are as follows:

-the copy stalls

-all shares disappear from windows explorer

-server is unreachable by telnet and http

-if I unplug the ethernet cable from the server and then plug it back in, the web UI and telnet sometimes come back, but the shares never come back when doing this.

-I can do a clean powerdown from the local console

-parity checks are clean

-I have run extended smart tests on the drives with the files I'm trying to copy and they do not indicate any issues.

 

I rebooted, caused the crash to happen and then ran diagnostics.  I have attached the diagnostics file.

Do you have another computer to try to see if you can connect to the unRAID server after you have problems on the Win10 computer?

 

 

syslog only a few minutes long. Is this after the "crash" but before a reboot?

Try a powerdown (leave off for at least a minute)  of the Win 10 computer to see if access returns.  (If a laptop, make sure it is a true power-off and not a one of powered-down states.)

The diagnostic that I posted should only be a few minutes long.  I rebooted the server, then induced the failure and ran diagnostics.

 

I just induced the failure again to try the troubleshooting suggestions.

 

Tried from another W10 computer and could not access shares, telnet or http

 

Tried http from an android phone (just to rule out windoze), no response.

 

Rebooted the W10 computer that I was copying to.  No change

 

Cycled power on my router.  No change

 

Cycled power on my switch.  Now I can access telnet and http but no shares.  (Same that sometimes happens if I just disconnect and re-connect the network cable at the server)

 

Rebooted server and all services including shares are back.

I guess we can call this one closed.

 

I just changed the server patch cable from STP to a brand new UTP cable and plugged it into a different port on the switch.    Now the shares are back online and I just copied 100GB without inducing the failure....

 

I have no idea if it was the cable or the switch, but I'm done troubleshooting for now.  Thanks to Frank1940 for shifting my attention away from the server and to other pieces of the puzzle!
