Thunderbay 4 TB3 48TB keeps having constant activity, after indexing
Not sure why my 48TB RAID5 (26TB used) had to re-index itself, but off it went, yesterday, and kept going all night, which does annoy quite a bit, after a while, with all that rattling of the drive-heads...but this morning, with indexing having finished, it just keeps rattling, for no apparent reason...what could it be?
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.
Are the disk lights active? if not, when you say "rattling" are you hearing rattle as in something loose?
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.
This morning, when I turned the TB4 on again (since my work-desk in the same room that I sleep in, I turned it off for the night so that I can sleep in relative silence), it went through its initial boot process with some disk activity and has now "settled down" for the first time since re-indexing.
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!
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.
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.
