Hi,

I get an error when I try to increase pgpènum, because the first command doesn't work:

#ceph osd pool set Backup pg_num 1024
set pool 6 pg_num to 1024
# ceph osd pool set Backup pgp_num 1024
Error EINVAL: specified pgp_num 1024 > pg_num 64

Than you,

Cabeur

HI,

Always increase the pg_num and pgp_num ...

Ex:

$ ceph osd pool set rbd pg_num 512
$ ceph osd pool set rbd pgp_num 512

Usually from what I know you can ONLY increase the pg and pgp number...

What error do you get ?

Thank you,

Bogdan

Hi all,

I am using ceph 14.2.1 (Nautilus)

I am unable to increase the pg_num of a pool.

I have a pool named Backup, the current pg_num is 64 : ceph osd pool get
Backup pg_num => result pg_num: 64

And when I try to increase it using the command

ceph osd pool set Backup pg_num 512 => result "set pool 6 pg_num to 512"

And then I check with the command : ceph osd pool get Backup pg_num =>
result pg_num: 64

I don't how to increase the pg_num of a pool, I also tried the autoscale
module, but it doesn't work (unable to activate the autoscale, always
warn mode).

Thank you for your help,


Cabeur.
