pancho Posted March 13, 2019 Share Posted March 13, 2019 (edited) Hello! I have recently encountered an issue with one of my most reliable unraid 6.6.7 servers. Over the past week, this server has periodically "dropped off the network" where I can no longer access the ip (unable to ping) or use the console keyboard. The power is on, but without keyboard response, I have to shut it down forcefully. I have been trying to troubleshoot what exactly is causing the server to sporadically 'freeze' (hardware failure, etc.). Tonight, after an 'unclean' shutdown, I am now no longer able to load the array. The server will hang at 'mounting disks'. I have tried everything, but have had no success. I just see the following screen (shown in safe mode): I am stumped if this is due to an XFS disk error, or something else. Attached is the most recent diagnostics dump. mediahub-diagnostics-20190312-2031.zip Anyone have any suggestions? Thanks.

dgreig Posted March 13, 2019 Share Posted March 13, 2019 Have you tried a New Config and reassign the slots? Quote Link to comment
JorgeB Posted March 13, 2019 Share Posted March 13, 2019 Try grabbing the diags after starting the array, use the console if the GUI isn't responding. Quote Link to comment
pancho Posted March 13, 2019 Author Share Posted March 13, 2019 Here is the updated diagnostics file (captured right after I started the array). I also ran a memtest on the server (2 passes), no errors. mediahub-diagnostics-20190313-1317.zip Ideas? Thanks. Quote Link to comment

pancho Posted March 14, 2019 Author Share Posted March 14, 2019 (edited) Johnnie, Just wanted to give a big thank you for all the help. It was indeed my Seagate sata cache disk that went belly up. I tried everything to read the data, in the end the drive was faulty. Swapped it out with a new SSD and I am back online. Running a parity check to be safe. Have to rebuild my dockers tomorrow. Lesson learned for not backing up the appdata folder. Will make sure I have backups for the future. Thanks again. Pancho Edited March 14, 2019 by pancho Quote Link to comment
