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.

1 x RAIDZ1 | 9 wide | 1.82 TiB

13.64 TiB

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?
