[Gluster-users] [Gluster performance tuning]how to determine the value of performcance.cache-size

[Jifeng Li]

Hi  ,

How do I  determine  the value of  performance.cache-size option  suitable for my glusterFS environment ? If I have large memory, can I set this value more larger ?

Now I have 6 nodes which have 4 bricks.

Volume info is shown below:
Volume Name: gv0
Type: Distributed-Replicate
Volume ID: 8968985c-9272-4b03-8078-cf3ed91f9fc2
Status: Started
Number of Bricks: 12 x 2 = 24
Transport-type: tcp
Bricks:
Brick1: adf-db1:/export/disk1/brick
Brick2: adf-db2:/export/disk1/brick
Brick3: adf-db1:/export/disk2/brick
Brick4: adf-db2:/export/disk2/brick
Brick5: adf-db1:/export/disk3/brick
Brick6: adf-db2:/export/disk3/brick
Brick7: adf-db1:/export/disk4/brick
Brick8: adf-db2:/export/disk4/brick
