May 21, 20242 yr Been working on this issue for a while and currently in the thick of it on the Unraid Discord if anyone can lend assistance (we've hit a dead end). All drives are regularly showing a read of approx 540kbps for 1 second, and it is happening every 60 seconds. Current setup is in safe mode, plugins/vms/docks/ disabled, SMB/NFS disabled, yet the issue still persists. Cant seem to find any entries in syslog lending an explanation either. maverick-syslog-20240521-1810.zip
May 21, 20242 yr Author @JorgeB UPDATE (Apologies for tagging you, I saw you had read the post already) Going through the terminal processes I was able to confirm the spike is coming from command: usr/sbin/crond The triggering command aligns perfectly with the reads happening on the array We don't really know what is happening there. Are you able to shed any light? Weird Read Spike.mp4
May 21, 20242 yr Author Further updates, but no solution as we need higher level assistance. We tracked the cron.d that was operating to the dynamix system monitoring that seems to now be embedded in Unraid. There is no way to block the command to test if it is the main issue and as soon as `update_cron` is run then the settings revert. Others dont seem to have the same issue despite this apparently being a new 'setting'. Not sure how to address this bug until we have a response from someone who understands whats happening.

It was the first we went to as it was the only one running every 60 seconds, but all the others that were there seemed normal as well. There were only 6 jobs running in safe mode, 9 total. Which of these do you believe could be the one causing an issue?
May 21, 20242 yr Community Expert You o not by any chance have the dynamix cache-directories plugin installed? That can cause excessive load if you have it badly configured so it not being limited in any way as to what it scans.

No sir the only dynamix plugins are currently System Temp and File Manager, but both are disabled in Safe Mode where the issue still persisted

May 22, 20242 yr Community Expert What do you have set in Settings -> Disk Settings -> Tunable (poll_attributes) ?

May 22, 20242 yr Community Expert Do the drives still spin down? It's normal for some drives, possibly only some brands/models, to show some activity when Unraid is accessing SMART, though in that case it should be every 30 secs, but as long as they are spinning down it's nothing to worry about

It's normal for some drives, possibly only some brands/models, to show some activity when Unraid is accessing SMART, though in that case it should be every 30 secs, but as long as they are spinning down it's nothing to worry about That's my main issue unfortunately. The drives will still spin down periodically, but only for 30-60 seconds at a time. They never stay spun down.
May 22, 20242 yr Community Expert To rule out any config issue, you can backup the current flash drive, then recreate using a stock Unraid install, only restore the key, super.dat and the pool folders, disable docker and VM services, start the array and retest.

Copy that. Will implement and report back.
