[Gluster-users] glusterfs missing files on ls

[Stefano Sinigardi]

Maybe I was not very clear in the previous email: even the forced rebalance
got stuck in the same folder (not many details in this case from the log),
counting million of files that were not existant, so I stopped that.

Then, before the following paragraph in which I described the fact that I
removed many files not on purpose, because I was stuck, the time suddenly
is skipped to "this past night" (I'm in japan)
