Upgrade Disks in a Thin Volume TVS-472XT

[obiwanKenobi]

I want to upgrade my 4 disks in this thin volume I set up
I thought I would be able to expand this volume along the lines of the upgrade to a RAID array as detailed here
https://www.qnap.com/en/how-to/tutorial ... ty-upgrade
But this does nto work for a Think Volume

Is there a similar approach to upgrading disks for this kind of volume?
Or do I have to back everything up and then upgrade the disks and then do a restore?

Thanks

thin/thick/static has nothing to do with the underlying RAID

Upgrade the RAID group
Expand the Pool
Expand the Thin Volume

Appreciate the insight/help @dolbyman
but I am a little lost (probably because I set this up wrong to start with?)
I see no raid option
All I see is all my disks and space assigned to the Thin Volume
I can see RAID group 1 and RAID Group 2' when I select individual disks on the 'Disks/VJBOD' menu option
Disks 1-4 are assigned to RAID Group 2 (Raid 5) 2 Tb each
My 2 SSD's are assigned to RAID Group 1 (Raid 1) 500Mb each

I use this as local storage via firewire to a Mac. Everything is backed up to another NAS at nighttime

I'd like to change out the 4 disks with new 4Tb devices I reclaimed from another NAS

Many thanks,

You change the 4 drives of your RAID 5 and go through the expand pool process (replace one by one> expand capacity)
That will expand the pool, after you can expand your volumes

[obiwanKenobi]

Just to confirm I am going to pull Disk 1 and replace with a new hard drive
Once I do that the QNAP settings panel will offer me an option to replace the missing drive with the new one and expand the pool

[dolbyman]

Just pull,replace,rebuild all 4 drives..then you go to the mentioned menu to expand the pool

[obiwanKenobi]

Many thanks @Dolbyman
Appreciate your patience with me. It all may seem obvious but my limited past experience and guidance has made me cautious in approach
Measure twice, cut once as they say
My Raid is currently rebuilding and I will progress through the sequence

[obiwanKenobi]

So all drives replaced with 4Tb but space remains the same
When you say 'Expand the pool' you mean re-size the volume option on Storage/Snapshot menu or is that 'Expand the Thin Volume'?
Currently it is allocated at 5.6Tb - the max it appears to allow in the option is 54,163 Gb or 54 Tb?
I forgot to mention I have x2 500Mb SSD devices in a separate Raid Group 1

[dolbyman]

pool expansion is done after all drives were swapped(see my previous post up on how to expand it)

thin volumes can also be overprovisioned ..so be careful what you set them to

[obiwanKenobi]

Thanks - I am trying but I just don't seem to make sense of this
When I access the resize volume I am presented with this screen (the values appear when I enter this screen)

And if I accept these values I get this error

2021-12-05 Resize Volume - Warning.jpg

All of which I am struggling to make sense of
Why would this overprovision
I have 16Tb (x4 4Tb drives)
Even in RAID5 I should have 12Gb

I read this thread viewtopic.php?t=116369
But struggle with the directions since they do not line up with the menu options I see
The manual https://docs.qnap.com/nas-outdated/4.2/ ... olumes.htm
Refers to Storage/Storage Space but that's not what shows up on my interface

If those links don't work I apologize I tried multiple times with the Img tag but it said it could not access despite them being public on my dropbox
What am I missing?

This is before I get into thick and think provisioning

[dolbyman]

please upload screenshots to the forum not 3rd party pages

also post a screenshot of the pool management ..not the volume

[obiwanKenobi]

My apologies - I originally tried but failed to find the mechanism hence using outside service
Seemed as if it was not available but now I see the 'attachments' section to link to the tags (so much easier!)
I think this is what you mean this

2021-12-06 Storeage Pool.jpg

or this

2021-12-06 Storeage Pool Managment.jpg

[dolbyman]

that is the volume management...I said pool managment! (rightlick on pool and hit manage)

[obiwanKenobi]

OK - now I have found it

So from this screen I hit 'Expand Pool'
Allow qnap to do its thing

Then 'Expand the thin volume' (is that in the same menu tree or elsewhere)

[dolbyman]

no .. as said further up you go

Mange > replace one by one > expand (on bottom)
