cluster/distribute: Trigger selfheal only if rmdir succeeded once

2011-11-11T09:57:05+00:00

A EACCES error also should not trigger a selfheal.
Only if rmdir succeeded on any subvol, a selfheal should be triggered

cluster/distribute stat: Take ref on inode before to prevent crash.

2011-11-09T17:32:34+00:00

Possible situation is a forget call which unref's the inode, and the
layout gets freed before we access it in stat.
By taking a ref before we call ctx get, the layout is going to be
persistent till we unref it.

Also use local call_cnt var instead of layout->cnt when wind is
involved

cluster/distribute lookup: send revalidate calls to all subvols for directories

2011-11-09T17:27:58+00:00

If mkdir fails on a subvolume, layout is set taking into account
only the subvols where it was successful. stat does not trigger
selfheal, as its layout based.
Revalidate on directories needs to be sent to all subvols, to fix
the error, and not just on the layout.

stripe read: Wipe stat in reply to prevent truncated error.

2011-11-09T06:11:48+00:00

If the read request, does not fall to the subvolume with the largest
file size set, then we never return the correct size. This leads to
clients seeing a truncated file error.

The work around is to wipe stat being returned as part of read call.
