Hi all Operating big capacity HDD such 8TB with complex filesystems like BTRFS in RAID mode endup in dmesg get flooded by this log, due too many capacity checks (opaque to the filesystem itself) The logs come from here: https://elixir.bootlin.com/linux/latest/source/drivers/scsi/sd.c#L2508 The general guideline tells that KERN_NOTICE (which is the default log level for dmesg in most distribution) should report information for any user interest I think that this information is not really of user interest, rather more of DEBUG interest So my suggestion is to lower this log to KERN_DEBUG Do you agree? Bye
