Attach existing qnap disk without formatting

[alexstosic]

I wanted to restart from scratch
I've installed a new hdd and setup the nas as new.

I want now to add the old disk and copy over all files to the new drive
When adding a pool and a volume, qnap ask to format the drive.

I read somewhere add without format can be done vial shell/cli but can't find any info

TS-253 Pro dual slot, new disk is now system drive in bay 1
old system drive with data in it is now in bay 2

[alexstosic]

I can see the drive

Disk /dev/sdc: 4000.7 GB, 4000787030016 bytes
255 heads, 63 sectors/track, 486401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 1 267350 2147483647+ ee EFI GPT

that's exactly why you need external backups (and for other disasters)

see if you can recreate the old shares (under new names) and point them to the old volume (if it is mounted)

also a NAS doesn't need spontaneous reinstall .. any reason for the reinstall ? malware ?

[alexstosic]

Old disk is still bootable but kept crashing regularly (at least every week) that's why I wanted to start fresh,
I need to copy over to the new disk, without having to have a third disk/device to perform the migration.

[alexstosic]

QNAP support suggest to mount the hdd on an another PC and move it from there, I'll try soon and let you know.

currently recovering with r-linux (although the disk and partition was perfectly fine)
4TB will probably take a week
