- Subject: [PATCH 0/2] mdadm: setting device role of raid1 disk with failfast
I've found a case that failfast option of mdadm set a disk faulty wrongly.
Following is my test case.
mdadm --create /dev/md100 -l 1 --failfast -e 1.2 -n 2 /dev/vdb /dev/vdc
mdadm /dev/md100 -a --failfast /dev/vdd
If I use failfast option, the vdd disk was faulty wrongly.
If not, it was spare.
This patch fixes a corner case for setting device role and
prints device role if it's faulty.
This patch is based on "mdadm - v4.0-8-g72b616a - 2017-03-07".
