@appstore Disk Migration


Question

Hi,

 

I would like to know how I can move my App Disk from 120GB to 500GB Disk.

 

So what I mean is that i have the @appstore on the 120GB with all packages installed. Now i want to move this to my new 500GB Disk.

 

What is the best method for this please.

 

Thanks

OK. That will teach us to follow some guide on the internet!
So what do you have now?

First of all, did you take the original (120GB) disk out?

If the 500 is storage pool 2 is there a storage pool 1?

and what does it say for RAID type?

The 120GB is out and the 500GB is in.

 

It is on Storage Pool 2 and when i ran that command it fixed the RAID Errors and now it is just an Single Disk.

 

The 500GB is showing as an 120GB Disk.......

 

So what i want to try next is add a new 500GB Disk and set it up in RAID 1 and then see if it will allow me to Expand it if not then back to the start.....

When I restarted, the storage pool had crashed

 

Not to nit, but in Synology-speak, "degraded" and "crashed" are two very different things.

 

FWIW I think it started expanding automatically after resynchronizing operation completed, and was in the middle of it when you removed the second drive.  mdadm is pretty resilient so it didn't cause any problems.

Hi @flyride

 

It was degraded and i ran "sudo mdadm --grow --raid-devices=1 --force /dev/md3" Since it was on Storage Pool 2 It worked as it stated.

 

I setup the RAID 1, Waited for Re-Sync to be 100%, Shutdown and removed the 120GB, Powered up and got the degraded error and ran the command via SSH. - 
"raid_disks for /dev/md3 set to 1"
 

Once that was done the degraded error changed to Healthy and that was it. There was no option to expand or even seeing the disk to expand nothing at all.

 

Should i try this again ?

If I understand what you have done, you used the RAID1 to clone your 120GB to the 500GB drive and then dropped it back to a Basic volume.  My instructions were to replace the 120GB in the RAID1 with another drive which has to be 500GB or greater.  Only then will the volume be expanded.  After it is done expanding, you can remove the extra drive and drop the RAID1 back to Basic.  I think you skipped the part with the extra drive.

mmm Ok so there is 2 Different things here.

 

I tried the Single Disk Method and that failed so now will have to go buy 1 more 500GB and Try this..

 

Thanks

 

EDIT: I have started over now. My 120GB and 500GB is in RAID 1.

YAY :)

 

Finally it worked with 1x 500GB Disk. I found my issue and it is solved.

 

I had to Wipe the 500GB First and then make the RAID 1. Shutdown remove the 120GB run the command then Expand the Storage Pool & Expand the Volume.

 

Thanks alot both :)
