Bulk Expand Pool

I want to expand my Pool on Truenas scale. I have added 5 new drives of the same size to my systems and all are detected. The GUI gives the option to expand 1 disk at a time. Is there any way to expand multiple disks (all 5) at a time instead of doing one by one?

Hi and welcome to the forums.

Please share your existing pool layout and system specs for better advice.

Unable to share ss here.

No, but you can initiate all five replacements at (almost) the same time; you don’t need to wait for one to finish in order to begin the next. Start all five, wait for them to finish, remove the old drives.

I am not replacing the original drives. All are of 2 TB, the old ones as well as the new ones. I am just adding new drives to expand the pool. Instead of doing one by one, wanted to see if it could be done in parallel.

Indeed, my bad. I don’t believe it can. But a 14-wide RAIDZ1 vdev is bad news in any event.

what config would you recommend in this case then?

A mirrored pair of 24 TB spinners would be much more sensible–I don’t see any reason to be putting 2 TB drives into production for the last several years.

Or maybe two 7wide raidz2 vdev striped together?
