Good morning,
I want know if possible clone the hd of nas with clonezilla.I have to replace disk 2 with one with more  space.The HD is configured RAID 0.

What are you actually wanting to do?

Since you say you have a RAID 0 array - that is two disks - and you want to replace one of them with a larger capacity disk.  If this is the case, adding a larger disk will not increase the array capacity but it might allow you to have a second standard volume in the free space of the larger disk.

Cloning the disk will not necessarily preserve the RAID array.  The safer method is to use your backup of your data (make sure it includes those things added since the last backup) to restore everything after you have formatted both disks.

Just remember a RAID 0 array can not be larger than twice the smaller disk (example: disk 1, 1.5TB disk 2, 2TB - array size = 2x1.5TB = 3TB)

Ok sorry I was wrong I don't have RAID.

No problem but it does make it simple for you to replace the disk with a larger one.  Depending on how much data you have on the disk you want to replace you can either just copy it to a USB disk or your PC if you have the space, replace the disk and copy it back or (not recommended unless you know what you are doing) remove the drive and put it in a USB/SATA caddy or adapter, install software that will read the Linux Ext2/3/4 file system on your computer, put the new drive in the unit and format it then copy from the old drive to the new one in the NAS.

Hello. I have two disk in JBOD mode. I want to replace one of them for a newer and bigger one. Is it possible to clone and replace it without losing all the info?

Thanks for your help

That is what backups are for!

Backup everything, replace disk, reformat and restore from backup.
