Neil,
I've noticed that the "check" operation no longer works for RAID10. It
works just fine for the other RAIDs. The ("data-check") sync_thread
kicks off just fine, sync_request_write() is called, but it never gets
past:
if (i == conf->copies)
goto done;
The test I am performing creates a RAID array, waits for it to sync,
shuts it down, writes random data to one of the devices, assembles the
array, and then runs a "check" - there should be descrepancies. The
descrepancies are found and recorded in resync_mismatches for all RAIDs
<= 3.9 and only for non-RAID10 3.10-rc1+.
I'm sorry I haven't tracked it down yet and I'm going to be on vacation
starting tomorrow with only intermittent access to e-mail. Sorry to
leave you hanging.
Thanks,
brassow
P.S. This also reminded me of a patch I have concerning tracking the
last sync action for the purpose of making mismatch_count more useful.
I'll post that before leaving.
