[Gluster-users] 'Transport endpoint not connected'

[Brian Candler]

This should be a pretty easy issue to reproduce, at least it seems to happen
to me very often. (gluster-3.2.5)

After storage backend(s) have been rebooted, the client mounts are often
broken until you unmount and remount.  Example from this morning: I had
rebooted storage servers to upgrade them to ubuntu 12.04.  Now at the client
side:

$ ls /gluster/scratch
ls: cannot access /gluster/scratch: Transport endpoint is not connected
$ ls /gluster/scratch3
dbbuild  DBS
$ sudo umount /gluster/scratch
$ sudo mount /gluster/scratch
$ ls /gluster/scratch
dbbuild
$ 

Note that /gluster/scratch is a distributed volume (spread across servers
'storage2' and 'storage3'), whereas /gluster/scratch3 is a single brick
(server 'storage3' only).

So *some* of the mounts do seem to automatically reconnect - not all are
affected.

But in future, I think it would be good if the FUSE client could
automatically attempt to reconnect under whatever circumstance causes
'Transport endpoint is not connected'; clearly it *can* reconnect if forced.

Thanks,

Brian.
