I am struggling with setting up RAID5 for my workstation running Ubuntu. Having read a plenty of guides and tutorials I managed to:
- create a RAID5 array from 3 disks in Intel RST ROM Utility
- setup RAID array in Ubuntu using
- create ext4 filesystem on the dedicated volume and mount it
However, after rebooting everything just disappears (except BIOS setup), despite I have saved mdadm configuration (
mdadm -E -s) into
/etc/mdadm/mdadm.conf. I cannot see
/proc/mdstat shows no arrays.
Am I doing something wrong? Maybe there is a secret how to make my RAID setup persistent?
Thanks in advance.
