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:
# getfattr -n trusted.glusterfs.pathinfo
./_base/1c1133f82c49bf66bde3625f3518bef159e3b6e2
# file: _base/1c1133f82c49bf66bde3625f3518bef159e3b6e2
trusted.glusterfs.pathinfo="(<DISTRIBUTE:gv-nova-dht>

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
