It shouldn't be, 5.3.15 is missing an fsync after writing anything to
the log. So the messages are stuck in the stdio buffers. Either force a
logswap (volutil swaplog), or shut down the server and everything should
pop up.

Ok, rootvolume name is root-vol, this is looked up in the VRDB (i.e.
post-processed VRList) and gives replicated volumeid 7f000000, and
replica id 1000001. Then the replicaid 1000001 is looked up which id
found, although that is actually a volume ftwo.0 which itself believes
it is part of the replicated volume ftwo (volid 7f000002).

So this will cause some serious failures at some point.

Ok, so starting your client 'wiped' the server and the whole VRList is
basically useless because it describes a server state that doesn't exist

Returncode 22 is EINVAL, returned in some places when the lookup doesn't
turn up an entry in the VRDB (list of replicated volumes) or VLDB (list
of volume replicas). Once the volume is found the server that hosts the
volume according to the VLDB is queried for information and it responds
with 103 (VNOVOL) when it doesn't know about the volume.

We try to turn off resolution logging for singly replicated volumes,
however it passes the wrong info. I already got a fix for that checked
