[gpfsug-discuss] advanced filecache math

[Stijn De Weirdt]

hi all,

we are looking into some memory issues with gpfs 5.0.2.2, and found
following in mmfsadm dump fs:

>     fileCacheLimit     1000000 desired  1000000
...
>     fileCacheMem     38359956 k  = 11718554 * 3352 bytes (inode size 512 + 2840)

the limit is 1M (we configured that), however, the fileCacheMem mentions
11.7M?

this is also reported right after a mmshutdown/startup.

how do these 2 relate (again?)?

mnay thanks,

stijn
