Upgrade from 6TB to 10TB drives

[dturner71.dt]

So I have 8 x 6TB drives currently installed and want to upgrade to 10TB drives. I could create another ZVol and move the data, but considering how many issues I had getting my plex going, I'd rather avoid a reinstall on the new volume. Current data :

[root@Server ~]# zpool list

Is it easy to upgrade each drive, or should i just move the data? Anyone have instructions on the upgrade process?

Thanks guys.

If you have the drive bays, you should be able to use ZFS send/recv to move the datasets, rename the old pool and rename the new pol to mach the old one, reboot and that should do it.

Also you see that CMD button when you making a new post? Click that and then paste you contents in between the tags ;)

Use the CODE buttons for terminal output, it keeps the formatting better.

Yes, easy to do. You can just replace one drive at a time in the same way you would replace a drive that was defective and once all the drives are replaced, you get the benefit of the extra space. Or, if you have room, you can just add a second vdev to your existing pool and have two vdevs of 8 drives each all in one pool together. Or, you could do the first option and then come back and add the 6TB drives as a second vdev. So many options.

If you put that text in code tags, it looks nicer:

Did that answer your question?

How do i go about replacing one drive at a time? Commands needed or is it automatic? Thanks.

Also, have you looked at the manual? I feel like it might be covered in there: http://doc.freenas.org/11/freenas.html

 

[pro lamer]

If you are a bit careful reading themanual you will be able to replace in-place. In-place = I mean: your pool doesn't get into degraded state even for a moment. As the others mentioned above: one drive at a time letting the pool grow (the manual, chapter 8, look for "grow" phrase there to make sure it is done in-place)

I could create another ZVol

No, you could not. You could create another pool. A zvol is a special type of dataset that provides a block device.

Yes, it is exactly covered in there.

The easy path to upgrade your capacity, although it will take some time either way, is to replace one drive at a time. If you chassis has sufficient space and power, you could have both sets of drives connected and create a new pool on the new drives using the zfs send | zfs receive that was linked above. That does work. I have done it, but given the amount of data you have, it will take several days to transfer it all to a new pool. It will also take several days to resilver one drive at a time. The advantage of the zfs send | zfs receive is that it would totally eliminate your fragmentation which the individual disk replacements will not do.

Please ask if you have any further questions about the process.
