setting up RAID 1 with mdadm
by Gilles Detillieux 18 Oct '18

18 Oct '18

Circumstances finally forced me to bite the bullet and learn something I had been putting off for too long: setting up a RAID array under Linux. I'm almost embarrassed, now that I've done it, that I waited so long because it was way simpler than I'd imagined. I thought I'd have to figure out all kinds of magic with LVM, parted, and mdadm, but I found this tutorial that showed a simple set of mdadm commands to set up RAID 1: https://www.digitalocean.com/community/tutorials/how-to-create-raid-arrays-… This was actually one of the simplest scenarios: the system had an SSD for the root/boot partition, and two 2 TB hard drives for data storage (/dev/sdb & sdc), so I just needed to set up RAID 1 and not worry about the intricacies of booting from RAID. So, software RAID seemed like the quick & easy way to go with a minimum of fuss. Now the nagging question: is it really this simple, or does the tutorial above oversimplify and omit some important steps? Can someone with ample RAID and mdadm experience advise or provide tips on anything else I should do or lookout for? Thanks, Gilles -- Gilles R.

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, October 9. The meeting topic for this month is as follows: Reproducible Builds Many of us run some amount of Free and/or Open Source Software, but how can we ever be sure that what we're actually running was built from the allegedly published source code? Whilst not a complete security solution in and of itself, find out how this project helps influence and improve security and development as part of a wider set of policies. Presented by Muz. RTFM: netcat, with Wyatt Zacharias A look into a computer networking utility for reading from and writing to network connections using TCP/IP protocol, designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ******************************************************************* Please note our new meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.
