Hi Test case: calling getcwd(3) in a directory on NetBSD - glusterfs release-3.3 has no problem - glusterfs 3.2.7 has a funny bug when a node TTL is expired *and* if the getcwd program is stored in the glusterfs volume. # cd /gfs/manu/bugB4 && /gfs/manu/getcwd/getcwd && sleep 2 && \ /gfs/manu/getcwd/getcwd getcwd = "/gfs/manu/bugB4" getcwd = "(null)" # cd /gfs/manu/bugB4 && /tmp/getcwd && sleep 2 && /tmp/getcwd getcwd = "/gfs/manu/bugB4" getcwd = "/gfs/manu/bugB4" When it fails the client logs say: [2012-08-09 06:45:37.338851] W [inode.c:180:__foreach_ancestor_dentry] 0-: per dentry fn returned 1 [2012-08-09 06:45:37.339021] C [inode.c:232:__is_dentry_cyclic] 0-gfs/inode: detected cyclic loop formation during inode linkage. inode (-5514238854638478444/20958215-feaa-4648-acde-5f3e8da776e5) l linking under itself as .. [2012-08-09 06:45:37.339112] W [inode.c:844:inode_lookup] 0-: inode not found Is that a bug in glusterfs 3.2.7 or an inaccuracy in NetBSD FUSE? Here is getcwd sources for anyone willing to test: /* cc -o getcwd getcwd.c */ #include <unistd.h> #include <stdio.h> #include <sys/param.h> int main(void) { char buf[MAXPATHLEN + 1]; (void)printf("getcwd = \"%s\"\n", getcwd(buf, MAXPATHLEN)); return 0; } -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu@xxxxxxxxxx
