amateur_wizard Posted June 12, 2021 Share Posted June 12, 2021 md_write_method when set to Auto or Reconstruct Write causes instability. To be sure of this I set the system to the classic read/modify/write and allowed the uptime to continue to 40 days. I then set it to auto and within two days the system was inaccessible and required a restart. Quote Link to comment
Squid Posted June 12, 2021 Share Posted June 12, 2021 Can your power supply handle all the drives spinning up? Quote Link to comment
amateur_wizard Posted June 12, 2021 Author Share Posted June 12, 2021 (edited) Yes, I checked that the rail that powers the drives has enough and it's well within margin. 750W PSU with 12 drives. Edited June 12, 2021 by amateur_wizard Additional Information Quote Link to comment

JorgeB Posted June 13, 2021 Share Posted June 13, 2021 You can enable syslog mirror to flash than post that after a crash, might be something visible there. Quote Link to comment

Are you using the Auto Turbo-Write plugin, which modifies the Auto option? 16 hours ago, amateur_wizard said: The rail info they show is at the bottom. I checked the specs. It has a single +12 volt rail, which is good, but can your power distribution cope with 12 drives? Are you using splitters? Quote Link to comment
amateur_wizard Posted June 18, 2021 Author Share Posted June 18, 2021 (edited) I did it twice and got the same result. I am not using the turbo-write plugin. I'll try enabling syslog mirror to flash and see what happens. Edited June 18, 2021 by amateur_wizard Additional Information Quote Link to comment
