Cloning Proxmox VE hard disk to SSD with the same size.

[LeoTecno]

Hi! I would like to switch from a hard disk to an ssd with the same size, in my proxmox server. If i clone them with Clonezilla, does everything work or do i have to make changes? Thanks!

When cloning the whole disk on block level sector by sector this should work.

Ok, i will try that

Hi,

I would try to use zfs send/recive from hdd to ssd, this is much safe, simple and faster.

Good luck/Bafta!

He is probably not using ZFS when using a single system disk and even then stuff like the ESP/bootloader would be missing as this is never ZFS.
So I would stay on the block level for cloning it.

Or aren't we talking about a bootable system disk?

Hi,

Yes, it is possible ...!

I've never heard of ZFS and i have a single disk in my proxmox server. So if i clone it with Clonezilla is it ok?

Yes, then use a Live Linux with "dd" or boot a clonezilla if you want a UI.

you should check if blocksize of ssd matches blocksize of hdd, otherwise you may get performance impact

 

[LeoTecno]

Ok, thanks everyone

 

[LeoTecno]

Sorry, just some info. Is it normal that Clonezilla has been cloning Proxmox's disk for almost two days now ?

 

[_gabriel]

yes, if it's a cheap SSD.
moreover, dd copy all disk even zeroes

The SSD is a Crucial MX500

 

[_gabriel]

not the worst, then size of disks ?

 

[LeoTecno]

500GB

 

[Dunuin]

Then it sounds a bit long.

 

[_gabriel]

indeed, it should be done in less than 2h , if source disk is read at 100 MB/s ...

 

[Dunuin]

The question is if it would read/write with 100MB/s. I remember a "dd -bs=512B" not being fast...not sure what blocksize clonezilla will be using...

 

[LeoTecno]

(It's still cloning... two full days)

Which tool did you choose to use? "dd"? Please post the command you executed!

Without any explicit "status=progress" option "dd" runs silently and does not show what is happening.

Read (for example, first hit in my search engine) https://www.baeldung.com/linux/dd-monitor-progress to learn how to tell the running "dd" to tell the progress by using a signal called USR1.

Good luck
