Here is where I will tinker with the Linux MDADM command “Multiple device admin”. I will make volumes both in Virtual environments, mostly Virtual Box by Oracle and physical sets. I want to do this to learn and write about performance and hardware failures. In case I ever encounter these error in the PROD environment I will have experience with it.
Virtual Sets are important for odd settings, long build and creation times. I can create virtual disks on an SSD for faster results. I also have the ability to roll back with VM snap shots when my tinkering had wonderfully unexpected results. That is why I do this, I love discovering things.
That moment when you say “ This is interesting….“
Physical Sets are important to build for testing performance and life expectancy of hard-drives, controllers, cabling and external cases. Some setups that may work in VM may be impractical as a physical set.
I will link all the resources that I found helpful here and give credit where credit it do as I build a repository of MDADM knowledge here.
I have a variety of hard-drives at my disposal and even a QNAP network device.
On my to-do list now:
- Desktop drives vs NAS drives
- Controller cards to host physical sets
- Branded Enclosures
- Troubleshooting a broken Volume
- Having a Cold backup – Why its best practice to have a backup of your data regardless of raid .
- Marvell Controllers
- Silicon Image Controllers
- LSI / Intel Branded Controllers
- The differences in shielded eSata cabling verses standard sata cabling.
- Performance differences
- Intentional breaking of volumes for the fun of repairing and testing for data integrity.
