protocol/client: Look only for op_ret while handling a setvolume response.

2010-01-23T18:37:17+00:00

op_errno should not be looked up to stop processing setvolume_cbk().
This fixes the problem of 3.0.x clients crashing if they attempt to
connect to 2.0.x servers.

Server backend storage hang should not cause the mount point to hang.

Submitted-by: Krishna Srinivas 
NOTE: fixed compilation issues in posix.c introduced while merging

storage/posix polls for FS/kernel being functional by issuing
statvfs() call. In case statvfs expires the timer, storage/posix will
send CHILD_DOWN to upper translator. Ultimately this will cause
protocol/server to disconnect all clients connected and also cleans up
the data structures. Hence if soft lockup or other kernel bug causes
backend FS to hang, the clients will not be hung.

resolver: handle resolutions of paths

2009-12-06T19:44:48+00:00

support a new type of resolution where only the path is sent from the
client over the wire without inode/parent/generation numbers. this can
happen when cluster translators could not look up inodes on a server
and later when the server comes up applications issues operations on
the inode without a lookup (since they could be cd'ed inside). In these
cases the server makes the best attempt to resolve the path and perform
the fop on it

Revert "protocol/client: return ENOENT if inode context is missing"

2009-12-06T19:34:07+00:00

This reverts commit 4439876a34f2e5d19db0d8b05ce7d7722c1c466f.

This revert is necessary for path handle resolution to work over the
protocol where client/server talk only with the path, without inode
or parent inode and generation numbers
