[gpfsug-discuss] GPFS_CLEAR_FILE_CACHE fails on Read-Only FS

[Hannappel, Juergen]

Hi,
in a program after reading a file I did a gpfs_fcntl() with GPFS_CLEAR_FILE_CACHE to get rid of the now unused pages in the file cache.
That works fine, but if the file system is read-only (in a remote cluster) this fails with a message that the file system is read only.
Is that expected behaviour or an unexpected feature (aka bug)?
