Subject: raid5 - adding journal to an existing device?
Date: Sat, 25 Feb 2017 23:12:21 +0900 [thread overview]
Message-ID: <9447cf1f98aaade8ab5cd3f0ef724f79@admin.virtall.com> (raw)
mdadm manual specifies the following for create, build and grow modes:
--write-journal
Specify journal device for the RAID-4/5/6 array.
However:
# mdadm --grow /dev/md2 --write-journal /dev/sdc1
mdadm: :option --write-journal not valid in grow mode
Is it not yet supported, will never be supported, or am I simply trying
to use it in a wrong way?
Tried the following versions:
# ./mdadm -V
mdadm - v3.4-115-ge22fe3a - 29th November 2016
# mdadm -V
mdadm - v3.4 - 28th January 2016
