[HPDD-discuss] Adding Extended Attributes to a file in Lustre files system

Hiii, I was trying to add extended attributes to a file in Lustre file system using the following methods but could not succeed, as a normal user. Method #1 The below code fragment run from lustre client always shows "setxattr: not supported error" and asks me to be a root and modify the /etc/fstab file name = "user.test_name"; //value = (void) 0; value = 0; if (setxattr(argv[1],name,&value,sizeof(value), XATTR_CREATE)==-1){ if(errno==ENOTSUP) perror("setxattr: not supported error"); exit(EXIT_FAILURE); } Method #2 I tried using the below function (which does the same action as above), but lustre says "client code should not depend on md_object.h". static int mo_xattr_set ( const struct lu_env <cid:part1.03000405.01040203@calligotech.com> * /env/, struct md_object <cid:part2.05080409.07020805@calligotech.com> * /m/, const struct lu_buf <cid:part3.02020009.08090900@calligotech.com> * /buf/, const char * /name/, int /flags/ ) Is there any way to modify the extended attribute of lustre file as a normal user? Any help or guidance or tip would be appreciated. -- Thanks & Regards, Linda J
