I am trying to run the Code:
#include <stdio.h>
#include <unistd.h>
#include <lustre/liblustreapi.h>
#include <sys/types.h>
#include <pwd.h>
#include <string.h>
#include <errno.h>
int main(int argc, char *argv[])
{
struct if_quotactl qctl;
char szpath[FILENAME_MAX];
struct passwd *pw;
uid_t uid;
gid_t gid;
int rc;
pw = getpwuid(geteuid());
if (!pw) {
fprintf(stderr, "%s: getpwuid on geteuid failed!\n", argv[0]);
return -1;
}
uid = pw->pw_uid;
gid = pw->pw_gid;
sprintf(szpath, "/n/circelfs");
memset(&qctl, 0, sizeof(qctl));
qctl.qc_cmd = LUSTRE_Q_GETQUOTA;
qctl.qc_id = gid;
qctl.qc_type = UGQUOTA;
rc = llapi_quotactl(szpath, &qctl);
if (rc) {
fprintf(stderr, "%s: llapi_quotactl %s: %s\n",
argv[0], szpath, strerror(errno));
return rc;
}
struct obd_dqblk *dqb = &qctl.qc_dqblk;
printf("Quota for %s on %s: %ld\n", pw->pw_name, szpath,
dqb->dqb_bhardlimit*QUOTABLOCK_SIZE);
return 0;
}
Compiled using the Makefile:
CC=gcc
CFLAGS=-g
LIBS=-llustreapi -lm
RM=/bin/rm
EXECS = rquota
OBJS = rquota.o
all: $(EXECS)
$(EXECS): $(OBJS) Makefile
$(CC) $(CFLAGS) -o $(EXECS) $(OBJS) $(LIBS)
$(OBJS): Makefile
.c.o:
$(CC) $(CFLAGS) -o $*.o -c $*.c
clean:
$(RM) -f $(EXECS) $(OBJS)
The resulting executable is run as a regular user on a client.
Doing so however, consistently crashes the MDS server and the client. We are
running the current version of Lustre 1.6.5.1
Any idea what could be going wrong here?
Thanks.
Suvendra.
