Hi,
I'm testing out gluster 3.2.4 with 2 bricks and a few clients using the gluster client. The clients are FC14 and the bricks are running CentOs 6.
The problem I'm seeing is that when I have/use 32 bit compiled binaries that have to open large files, they cant do it on gluster, but they can do it on NFS.
I'm wondering why this is....
A example.
>df -T /gfs
Filesystem??? Type?? 1K-blocks????? Used Available Use% Mounted on
fs2:/GFS
??? fuse.glusterfs?? 11368538112 2791284608 8577253504? 25% /gfs
>pwd
/gfs
>cat file.c
#include <stdio.h>
#include <stdlib.h>
#define BUFSIZE 1024
int main(int argc, char *argv[])
{
? FILE *fp;
? fp = fopen(argv[1], "r");
? if (fp == NULL)
? {
???? printf("Couldnt open file %s\n", argv[1]);
???? exit (0);
? }
? fclose(fp);
? return 0;
}
>gcc -m32 -Wall -O2 file.c -o file
>ls -hs file-0.txt
9.6G file-0.txt
>./file file-0.txt
Couldnt open file file-0.txt
>gcc -m64 -Wall -O2 file.c -o file
>./file file-0.txt
>
Then on the nfs mount...
>df -T /nfs
Filesystem??? Type?? 1K-blocks????? Used Available Use% Mounted on
nfs1:/nfs
?????????????? nfs?? 5184863200 4845371648? 76115680? 99% /nfs
>pwd
/nfs
>gcc -m32 -Wall -O2 file.c -o file
>ls -hs file-0.txt
9.6G file-0.txt
>./file file-0.txt
>
>gcc -m64 -Wall -O2 file.c -o file
>./file file-0.txt
>
I'm wondering why the 32 bit binary has no trouble on a standard nfs mount but it does have trouble on the gluster mount with the gluster client.
Thanks,
Brian
