Summary: why are idle RAID1 devices using CPU?
I have a Sun Netra X1 (ultrasparc @ 440MHz) running 2.6.19.1.
There's one little modification I made to it: instead of 2 SCSI disks,
it has one SCSI and one SATA disk (and a PCI SII 3512 card to connect
it).
Both disks are basically partitioned identically except for the
remaining space on the SATA disk (200GB whereas the SCSI is 72GB), that
space is a separate partition.
I've made a couple of RAID1 devices, using the "pairs" of partitions,
with a bitmap for quick resync in case of problems.
This works fine, but I noticed that quite some time was being used by
the mdX_raid1 threads; even on a partition that's not even being used at
this time... (it was an empty mounted filesystem, but I umounted it to
be sure the filesystem code wasn't causing some IO).
My question is: why is CPU being used by the RAID1 threads, even for
those devices that are otherwise unused? What are they doing?
I even started distributed-net to check that it wasn't just idle CPU
cycles that were being used :-)
Note: it did seem that the activity was a bit more during the first
day after booting; in fact, the mdX_raid1 threads together had used
about one hour's worth of CPU in the first 24 hours, i.e. 4% CPU
(according to ps and top).
thanks,
Paul Slootman

First-time synchronization (if applies), otherwise I suspect some
housekeeping (bitmap perhaps?).
Otherwise it seems like a question who does what. On a raid5 array (i.e.
cpu-heavy), both smbd and mdx_raid5 accumulate time for, of course, xor
calculation.

No, I had rebooted after the initial synchronization was complete.

On those devices that are actually in use, I'd understand CPU being
used; but where the device is not even mounted or used for swap or
whatever, I find that amount of CPU usage very high for just checking
the bitmap... I may take the idle device apart and reassemble without a
bitmap to see whether that makes any difference.

Sounds like a bug to me. My box is x86_64, but it's been up for 2 days and one
unmounted md_raid5 has used 0 minutes, 0 seconds of CPU, which is what I'd
expect.
Maybe it's some sort of accounting problem on SPARC?
