Add 'noatime' or 'relatime' in order to reduce additional I/O that is
used to update access time for the files on the bricks themselves.
Also, you can use 'inode64' as a mount option.

You need to add the bricks in replica set (which means 'replica 2' -> 2
bricks at a time).
So it should be like:
gluster volume add-brick dbroot1
10.1.1.60:/usr/local/mariadb/columnstore/gluster2/brick3
10.1.1.61:/usr/local/mariadb/columnstore/gluster2/brick3

Removal of bricks is also done in replica sets (which means 'replica 2'
-> 2 bricks at a time).
So it should be:
gluster volume remove-brick dbroot1
10.1.1.60:/usr/local/mariadb/columnstore/gluster1/brick1
10.1.1.61:/usr/local/mariadb/columnstore/gluster1/brick1 start

> gluster volume remove-brick dbroot1

Status should be checked with the same command used for start:
gluster volume remove-brick dbroot1
10.1.1.60:/usr/local/mariadb/columnstore/gluster1/brick1
10.1.1.61:/usr/local/mariadb/columnstore/gluster1/brick1 status

Same for commit:
gluster volume remove-brick dbroot1
10.1.1.60:/usr/local/mariadb/columnstore/gluster1/brick1
10.1.1.61:/usr/local/mariadb/columnstore/gluster1/brick1 commit

Repeat for dbroot2 just like for dbroot1.

Yes, any node in the cluster.
P.S.: If you which , you can leave the old disks and just do a
rebalance :)
Happy hollidays to all!
