Ah, I see where that comes from. The inconsistency threw me off. I
always forget that the servers don't know their own peer names.
No no, pathinfo is computed on the same machine where the brick resides,
so this is not that issue. Brick will return the string returned by
hostname() on the machine where it resides which could be different than
what you are expecting is my feeling. Please give the output of that
program please.

Joe,
Could you send the output of following program on one of the
machines?
11:24:31 :( ? cat tmp.c
#include <stdio.h>
main()
{
char hostname[256] = {0};
int ret = 0;
ret = gethostname (hostname, 256);
if (ret == 0)
printf ("hostname: %s", hostname);
}

I can't see any place the hostname is getting mangled for
trusted.glusterfs.pathinfo output, but I'm getting this and wanted
to know if that's expected behavior:

./_base/1c1133f82c49bf66bde3625f3518bef159e3b6e2

It's confusing because we have hostnames like "storage06" and
"storage02" in that output but the hostnames in the volume
definition don't match as they're "storage06-stor" and "storage02-stor":
$ sudo gluster volume info gv-nova
