Replacing drives with larger ones and gaining more space

[JohnnyD]

I have 4 x 6TB drives in a raid 6 with a btfs file system, can i replace the drives one at a time until each rebuilds with 14 TB drives, when and how many drives do i need to replace to get any extra space? How does the extra space present itself, is it just unnallocated space that I make a seond volune from?

Thanks

After you rotate all the drives you can use storage manager to expand the volume to its new maximum size

For me (I replaced first 4*8TB for 4*14TB in my SHR-2 combo at DS1817+ ) DSM did it automatically (expanded volume) after rebuild for each drive

I have 4*4TB and wish I could afford to upgrade to 4*8TB. How do you afford 14TB drives? I can’t just plunk down $1,600+ on a purchase like that.

How do you afford 14TB drives?

Some shuck drives from WD Elements or WD Easystore... For example, you can get 12TB for 240 USD, or 14TB for 290 USD... even better on promotions... but it is a gamble.

Then there is the question of how/where you back up all that stuff. RAID is not a substitute for backup.
