I once had a volume that continuously indexed (or had high kernel/task/MDS activity). No matter what I did. FInally, I did a backup restore to fix it. I don't know what is going on with macOS sometimes.

I thought I'd reply here instead of creating a new post.

I've been experiencing this lately as well. I recently replaced a disk and reconfigured my system. One of my two 12TB ThunderBay RAID5's keeps writing constantly. I deleted the Spotlight index a couple of days ago and it rebuilt quickly, but now it just writes and writes. I check indexing status (by typing "indexing" in Spotlight) and it shows no activity after the rebuild.

"Main" is the one that keeps writing. It seems to coincide with that kernel task.

Any ideas?

I don't really know of any other tool to see what is accessing files than Activity Monitor, which is clearly not designed to be user friendly.

I'll keep an eye/ear on it, but are there specific utilities/tools (aside from the "Disk" tab in macOS's Activity Monitor) that allow seeing what is accessing the disk?

Thanks for your help, so far, and have a good weekend!

Perhaps you need to delete the spotlight index, and let it reindex over the weekend. Internal volume access is 100% controlled by macOS, not SoftRAID.

yes, the disk activity lights are lit up…I shouldn’t have called it rattling, but since my enclosure is standing on an IKEA desk that isn’t made from solid wood, but hollow material, the disk heads’ sound is amplified to sound quite disconcerting, or downright annoying.

I found this thread, that complained of constant noise, but it seemed inconclusive, save for some suggestion of disabling ownership, but why?

Where should I start troubleshooting? I'm on the newest version of SoftRaid 6.0.5 on a MacBook Air M1 with 16GB RAM and 2TB of internal storage, running BigSur 11.5.2

Kindly give me your suggestions, please.
