hoping to find You all well.
I have a problem setting raid 6 onto my new CentOS stream 8...
Code: Select all
mdadm --create --verbose /dev/md3 --level=6 --raid-devices=10 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh /dev/sdi /dev/sdj
mdadm: layout defaults to left-symmetric
mdadm: layout defaults to left-symmetric
mdadm: chunk size defaults to 512K
mdadm: size set to 15625747456K
mdadm: automatically enabling write-intent bitmap on large array
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md3 started.

sudo mount -a
( any advice )
The doubt is that I have also update the sys... maybe I have an installonly_limit=3 that make problem on ssds ?
Code: Select all
cat /etc/yum.conf
installonly_limit=3
thx
