I have a filesystem created with this command:
mmcrfs gpfs01 -F discdesc_start -A yes -B 8M -i 4096 -m 2 -M 2 -r 2 -R 2 -K whenpossible -S relatime -T /tsm/back --metadata-block-size 256K
Because I have -m 2 and -r 2 I have two copies of data.
I changed my mind! I don't want two copies anymore :-)
How do I do that? The filesystem is in production...so I want to be safe with the commands :-)
Is it this command:
mmchfs gpfs01 -m 1 -r 1
I have two different faileregroups and one tiebreaker disk....I want to delete all the disks in faileregroup two and ofcause the tiebreaker disk
