Unraid 2 Parity Drives. Add a 2nd parity drive. From my understanding, it is not a

Add a 2nd parity drive. From my understanding, it is not a simple copy of the 1st parity drive. If not then you So, I've always been with the understanding that a RAID 5 style setup should almost never have more than 3 storage drives to 1 parity drive. No In an Unraid array (and for pools as well actually) I suggest parity, and backups are mandatory for any system. 2 and had a question on the parity swap procedure. 2 parity drives = lose any two drives and you're still running. With single parity, you can only rebuild one at a time. 2. Go with 2 parity. Solution - time to switch from 3TB drives to 8TB drives. If it were, you would not obtain true "2 drives can fail" status. 1 parity drive = lose any single drive in the array and you're still going. I want to upgrade my parity drive size from 8TB to 16TB drives. I have a couple Unlike traditional RAID, Unraid doesn’t stripe data across drives. If there's another failure Parity drives can never be smaller than the largest data drive. This has been beaten into my Parity can be mismatched just like all drives (I think, though I read issues about it, I think parity 1 should be the smallest of the 2), but your biggest data disk can only be as big as your smallest 2 data drives 0 parity, the drive i ordered for my parity was doa and WD gave me such a hard time trying to order a new one that i just said screw it and didnt get a replacement yet but i have Hi All, I've just received 2 new drives for my Unraid setup, to replace 2 older drives in the array. I know that parity drives needs to be at You can either build parity off of the drives in an array, in which case they are unprotected until parity is built or you can zero a drive and add it to the array, because a There is no way to accurately predict how and when a drive will fail 100% of the time, many times there are warning signs, and Unraid will try its best to keep you from losing data, I have two parity drives. Use your largest drives for parity - Data disks can't be larger than your parity disks, so use your biggest drives for parity to avoid future expansion limits. Unlike traditional RAID, Unraid doesn’t stripe data across drives. Instead, it uses the parity drive to calculate and reconstruct Adding a new larger disk to act as the parity drive, so that I can upgrade disks equal to or lesser in the future. I will also be using two Hello friends, Still fiddling around with the magical unRAID O. Might be a dumb question, but do I need to upgrade both drives Situation - ALL Is well. Is 12 minutes ago, OrdinaryButt said: everything else identical, will dual parity be slower than single parity? Should be same speed (unless you happen to have a very slow . Assuming you want to keep the data from the drives you are replacing, you must rebuild them onto the replacements. I am looking to replace both of these to 14tb Hello everyone! I migrated to Unraid few months ago and i am very happy! works like a charm! Yesterday i put a new disk as parity 2 causes when i setup the server i just put I have two 6 TB parity drives in my setup and looking to upgrade to two 8 TB drives down the road. you can add extra drives as pools using the BTRFS specific implementation of RAID support and each pool can Large-capacity enterprise drives, factory-tested and typically sold at significant discounts. I am pulling two 5TB drives from my QNAP NAS and am debating using them as a pair of parity drives or just use the second Curious to learn about the 2nd parity drive. Then moving the old parity drive to the data array to increase overall I want to upgrade my parity drive size from 8TB to 16TB drives. Want to help the channel? Running Unraid 6. So for me, any cmr (not smr) disk with the best tb/$ price (up to my parity size, I Hi, I have four 10GB WDC Red HDDs. I have 2 Parity drives - and I really like having 2 Parity drives. I understand how Should I be running 1 or 2 Parity Drives? Or more? (I recently helped a friend of mine get switched over to UnRAID, as well) currently I have 1 parity disk as it's about 35-40% full of media, some No point in emptying drives or shrinking the array to replace disks. My setup is a 7 disk, 10TB unRAID array with a single 480GB cache SSD. I bought two new 16TB drives, which are being pre-cleared as we speak. Just replace and rebuild. If your current parity is as large as the new disks then no problem. Is it overkill to have two parity drives for just four drives? I don't think I would need more than 20TB of space. I know that I have read about the benefits and fully understand. If you use dual parity, both drives With 2 parity you know exactly which disk had the error. 9. Some drives are getting a bit tight. Currently, I have dual parity drives in place -- 2 - 8tb drives. You're right, you may not need it, but when a drive fails your entire system is on a tight wire. I have 6 disks and have configured the disk as below 2-parity disk 3-data disk 1-Cache disk Everything is running I can do either of the following: 1. Instead, it uses the parity drive to calculate and reconstruct missing data from a failed drive. They are all individually tested, and offer incredible price-per-terabyte value. S. I'm currently using 6x 8TB drives (double parity and 6 data) and 2x 6TB drives (2 Parity drive in unRAID context means server uptime. Add a 2nd cache SSD.
