I’m spinning down part of my drives because they are only used periodically and I want to save power (and reduce noise).
This worked perfectly for a year or so but after upgrading from Freebsd-14.3-p7 to FreeBSD 15.0-RELEASE something is pulling them out of sleep with an interval of (what looks to be exactly) 10 minutes. Funny thing is that it doesn’t start directly after a re-start. In the beginning the drives are sleeping uninterrupted for somewhere between 30m to 1h15m (for the re-starts that I’ve checked).
I’ve disabled smartd (not starting it) and this did not change anything so I assume it is not responsible.
The drives that I put to sleep are used for two ZFS pools and one NTFS file system.
The NTFS drive is not affected by this issue. Does not matter if it’s mounted or unmounted.
Only one of the pools is in part made available as a samba share. The other is not, leading me to believe that samba has nothing to do with the problem.
Unmounting the pool
An exported pool
And yes, reverting back to 14.3 removes the issue.
Any idea on what it could be? Or how I could find out what’s responsible?
Has something changed with ZFS that could be responsible for this behavior? I have not upgraded the pools.

Unmounting the pool
zfs unmount pool1 does not change anything. Drives are still periodically waking up.An exported pool
zpool export pool1 does not wake up any more.And yes, reverting back to 14.3 removes the issue.
