Greetings,
I hope this is the correct place to post this, if not I apologize.
I'm attempting work with extended attributes on gpfs using the C API interface.
I'm wanting to be able to read attributes and then based off that value, change
the attribute.
What I've done so far is a policy scan that collects certain inodes based of an
xattr value. From there I collect inode numbers. Just to clarify, I'm trying to
not work with a path name of any sorts, just inode.
There are these functions:
int gpfs_igetattrsx(gpfs_ifile_t *ifile,
int flags,
void *buffer,
int bufferSize,
int *attrSize);
and
int gpfs_iputattrsx(gpfs_ifile_t *ifile,
int flags,
void *buffer,
const char *pathName);
I'm looking at how to use iputattrsx but the void *buffer part confuses me on
what struct to use. I've been playing with igetattrsx to try to attempt and
figure out what struct to use based off the data I am seeing. I've come across
gpfsGetSetXAttr_t but haven't had any luck using it.
My question is, is this even possible to manipulate custom XATTRs via the gpfs
api? If so any ideas on what am I doing wrong?
Thanks,
Christopher
