Hello

I want to clear some question on this bug,

1. what's mdadm version fixed this bug ?

2. Did it just disable raid5 journal function, not raid4 and raid6 ?

Comment 5 Nigel Croxon 2017-12-13 11:42:17 UTC

Hello,

1.  mdadm-4.0-10.el7

2. Correct, it just disabled raid5 write-journal, and NOT raid4 and raid6.

Comment 6 guazhang@redhat.com 2017-12-13 12:07:18 UTC

Hello


from mdadm --create --help page, the  --write-journal has disabled, so I'm don't test journal function on raid4 and raid6.

my test script will run MD journal tests when "--write-journal" option in mdadm --create --help page

Is it Ok for you? 


thanks
guazhang

Comment 7 Nigel Croxon 2017-12-13 16:52:46 UTC

Yes, that is a good test to check to see if -write-journal is enable/disabled.

The second line below will NOT show up on mdadm-4.0-10.el7.

--delay=           -d : bitmap update delay in seconds.
--write-journal=      : Specify journal device for RAID-4/5/6 array
--consistency-policy= : Specify the policy that determines how the array

Comment 8 guazhang@redhat.com 2017-12-14 01:41:44 UTC
