Just Give Me the Beans!
Hello, I have been using ZFS where available for years so I'm not extremely familiar with MDADM but I do have 3 machines using it and have a question regarding it. By default 2 of these machines have a consistency-policy set to resync where the other is set to bitmap. I have read the manpage and see how to change it but I'm wondering what the pros and cons of each are? Thanks!
<--- Run xman to see that window.
Every month, I have mdadm do a consistency check on my RAID1 arrays. Don't remember where I read that was a best practice, just that it was. /usr/share/mdadm/checkarray is the command. I don't check what type of policy the array has.
I also run weekly SMART short tests and monthly SMART long tests across all non-laptop disks. I don't keep anything important on laptops. They are never the "system of record" for anything.
