Ok, that's interesting.
In the 1.4.4 openafs source I see; "Last Update" should never
appear as "Wed Dec 31 19:00:00 1969". A "0" date should instead
appear as "Never". However, "Creation" doesn't haev a check
for a 0 date and will show up that way.
My attempt to replicate your behavior failed; my newly minted volume
on a test server went offline instantly. This is intensely interesting
to me, but it is hopefully not related to your problem.
So here's some questions that might help:
/1/ what openafs version, os version, & CPU architecture
machine is your "vos" command?
Is your vos command built with any special options, such
as "--disable-full-vos-listvol-switch" ???
/2/ what openafs version, os version, & CPU architecture is
Is your fileserver built with any special options, such
as "--enable-fast-restart", "--enable-namei-fileserver", etc.?
normally I'd also ask about your db servers, but I don't think that's
related to this problem.
Also some experiments:
does running "vos examine" on a client machine with the
opposite byte sex change anything?
does running the "vos" commands (and creating a new volume) from
a client running the 'latest generation' of openafs change anything?
does "bos salvage fs1 fs1-a" fix this problem?
does "bos salvage fs1 -a" fix this problem?
Do either report anything in SalvageLog?
Does moving the volume to another server change anything?
Does touching a file in the volume change anything?
