Will safely detach volume do what I want?
I have a TS873 with five 8TB drives and one 16 TB drive (two free slots)
The system volume is on the M2 drives in raid one.
Each HD is in a separate static volume.
Each volume has a single shared folder.
I want to replace one of the 8TB drives with a new 20TB drive without deleting the data on the old drive.
My plan.
Put the new drive in a free slot.
Create a new static 20TB volume.
Use HBS sync to move(copy) the folder on the old drive/volume to new volume/folder.
Remove the old shared folder without deleting the data.
Safely detach the old volume, shut the NAS down and remove the old drive.
Each HDD has its own Volume, it means each HDD has its own Pool? Not making five 8TB HDDs into RAID like the system volume?
yes, each drive is a separate pool - no raid on the data drives.
Backups go to a TS462 that currently has three 20 TB drives
As share names cannot be the same, the new drive would have to get a different share name to copy to.
Yes, I understand you can’t have two shares with the same name.
This procedure for moving a shared folder explains that.
However, it tells you to rename the old folder before doing the copy.
If you do that the data won’t be available until the copy is complete.
It appears a better way would be to create a share on the new volume with a new name.
Next use HBS to copy the data.
When the copy is complete rename the old share and the rename the new share to the old share name.
However, I don’t know of HBS allows read access to the source during the copy (sync).
