mirror | TrueNAS Community SOLVED Drive backup using mirroring: how to restore? Hello! My setup is the following: 1 vdev with 3 HDDs, all 3 mirror of each other (so 3 x 3TB HDD, total available space = 3TB) 2 Drives are just going to spin all the time, mirror of each other, that's the redundancy The 3rd drive, I'll plug it in once every now and then (say: once per
SOLVED - Change stripe vdev layout to mirror - TrueNAS After confirming going from stripe to mirror was possible I went ahead and built my system with two storage pools An "main" pool with 2 x 8TB drives for bulk storage and a "fast" pool with SSD's At the time of building the "fast" pool I only had access to a single 750GB SSD Knowing that I could extend the pool later, I configured it as a stripe
Performance: RAIDz1 vs mirroring | TrueNAS Community For a personal computer (Unix) I have to decide between mirroring 2 SSDs or RAIDz1 3 SSDs After some reading, I found places that say mirroring is faster than RAIDz1 This doesn't make any sense to me Yes, RAIDz1 has to compute the parity info for the third disk But, CPU times (for
Reword pool Extend to Attach a Mirror to be consistent . . . - TrueNAS It may not be deliberate, but we do plan to support RAIDZ expansion in 2024 in this case adding a drive to a VDEV is an "extension" Makes even more sense to distinguish the 2 features! Make the "Extend" button actually extend a RAIDZ pool and a separate "Attach" button attach a mirror, as per under the hood CLI terminology
How to set up 2-way and 3-way mirrors. | TrueNAS Community A "3-way" mirror would have three columns and two rows, and would consist of two mirrors, of three disks each, striped together If you wanted to keep the same level of redundancy, this would be correct But there's nothing inherent in ZFS that would keep you from striping a two-disk mirror with a pair of three-disk mirrors, or vice versa
Protecting bathroom mirror from corroding around the edges In my bathroom I have a beautiful illuminated LED mirror It's now 10 years since I originally installed it - and over time, the edges have become de-silvered as the backing coat has corroded and p
How can I dispose of large glass mirrors? As far as getting someone one to pick it up and dispose of a large frame-less mirror properly, I found out (at least) in Houston, TX that Purple Heart, Salvation Army, Goodwill, and Habitat for Humanity (Restore) do not pick up frame-less mirrors of any size There was a local glass shop that was willing to pick it up, but they charged a fee
troubleshooting mirror vdev wont expand | TrueNAS Community The problem is that SCALE (using the GUI) to replace drives in a mirror vdev incorrectly put the swap as the second partition The first partition (a zfs-member) is now limited to 7TB, and thus the vdev can only provide 7TB
3 Drive Configuration | TrueNAS Community The drive prices for 16TB drives (specifically Exos) are pretty decent compared to 10TB I think, thus why I want 16TB Are there any downsides to a 3 way mirror? Would it allow two out of the three drives fail without incident? Also if you know any documentation on it that would help a lot Also with RAIDZ, adding drives to a pool later requires resilvering, does a mirror 3 way mirror require
