Well done Avi! I’ve done a video on this with a 2 bay Synology a few years ago and have gotten many positive comments over the years. I’m sure this 4 bay version will be very helpful to folks out there. Your delivery eases any potential stress users may anticipate. Great job!
Just upgraded two of my drives over the holidays and this video helped explain a few of the steps that Synology's website isn't giving enough context to, so I really appreciate your tutorial. Thanks!
Great video! Easy to understand and right to the point 👍👍 I'll be swapping my 4x8TB drives for 4x20TB drives and this is exactly what I was looking for
Good Video! The following comment is aimed at home users (like me!), for whom upgrading an entire NAS-Full of drives may be too expensive to do in one hit, so they look to take advantage of SHR's ability to handle different sized drives and plan to upgrade over the course of several months, as funds allow. This is a clarification of Avi's point about SHR allowing only expansion after half of the drives in his 4-Bay unit were replaced: When the first drive is replaced (with a larger drive) you will NOT see any increase in available space. This is due to the way SHR works - the parity drive will only contain data equivalent to the largest drive in the active volume, any additional space will be unused. So for example in a 4-Bay unit with 4 x 4TB drives - the available space will be 3 x 4 = 12TB with the other 4TB drive used for parity. If you replace one of the drives with a 10TB drive, you WILL NOT see the extra 6TB. This is because SHR will use the new 10TB drive for parity to hold a 4TB parity image - because it cannot hold a 10TB image on a 4TB drive - Only when one of the remaining 4TB drives is replaced (with another 10TB drive) will the "missing" 6TBs become available - SHR will now be able to use one of the 10TB drives for parity and be able to hold an image of largest drive (the other 10TB unit) in the active volume. As I noted above, for Home users upgrading one drive at a time, they have to look at the first drive replacement as an "investment" - or they budget for 2 drives in the initial upgrade.
Great video! I could really use some help with some direction/advice... 1. I have a 6-bay NAS in RAID10/BTRFS. 2. I just added a 5 bay expansion chassis and 2 new 18TB drives, identical to the main NAS drives. 3. In storage > Volume 1 I am only seeing the option to replace a drive, but not add a drive 4. Everything is healthy, however I'm getting a low space warning. (Down to 10% remaining capacity) Is RAID10 configuration not able to expand? I'd much prefer expanding the current storage pool vs adding a new one, and having to change my file structures and shares. I'd be grateful for any advice!
Thanks for the video mate, just upgraded from 4 x 8TB drives to 4 x 12TB drives, which turn up tomorrow. I would recommend (if you haven't done it already) that you explain to people how to "shuck" external drives to internal drives for a NAS, WD Elements drives for example :) people can save money buying the WD Elements drives for NAS purposes, that's what I've done! Well explained video, thank you, I've got low drive space at the moment, so I get a Warning on the Storage Pool due to low available space, but if I follow the steps how you explained I should be fine I think.
Thanks this is almost all the information I wanted to confirm. The only thing I wanted to hear someone with experience tell me is if it is true that when doing this upgrade to higher capacity drives, do the newer, higher capacity drives have to have the same RPM as the older, lower capacity drives? For example, my RAID 1 has 2 4TB drives with 5400RPM and I wanted to upgrade to 2 12TB drives with 7200RPM. So do I need to get 5400RPM drives instead or is it possible to make this migration? My file system is btrfs, in case it matters. Thanks!
My storage pool 1 has 1 drive with 8tb volume. Yesterday i did expand drive and already added new drive 8tb. Now my storage pool 1 has 2 drives, but the volume didin't change. Still has 8tb. i would like to know how to solve this case and and my volume 1 change to 16tb.? thank you so much
Is this possible even if all drives are nearly full? I just bought 224+ with two slots and two 4TB drives. What if both are at lets say are at 90% capacity and i want to replace one with a 8 or 12TB drive?
@@TechMeOut5 Thx for the fast answer, still dont understand the logic behind it that its possible to restore data on a new drive even if the data is absent...
Going from 3TB to 4TB doesn't seem like it's worth the risk or the cost per TB gained. A larger jump in size has the same risk and effort but a lower cost per volume and is more future proof.

Loved the video, Avi! Get this question all the time and will be pointing people straight to this video! Great work!

why is my Volume missing the "Modify Size' option??

If the you configured raid1 or shr1...then yes
@@TechMeOut5 Thx for the fast answer, still dont understand the logic behind it that its possible to restore data on a new drive even if the data is absent...
Its possible only (in your case) if your volume is configured in raid1 or shr1

This was mostly for demonstration purposes. Just to clearify the process. The numbers are pretty irrelevant actually
Agreed, the comment is mostly for others that read the comments to encourage them to "go big".
