[Gluster-devel] ls again

[Jordi Moles]

Hi,

yes, i realised that. The thing is... as i said... nothing has changed, 
a part from gluster version. Disk were and still are ok. Just in case... 
i performed a whole fsck of each disk, but no error was reported.

is there any other explanation for that issue?
