June 12, 20215 yr 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.

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?
June 18, 20215 yr Author 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, 20215 yr by amateur_wizard Additional Information
