Hi!
On Sunday i sent a report about my whole home directory becoming orphaned.
Derrick J Brashear has guessed, that it may be the "CopyOnWrite failure" bug,
that several people on this list have experienced, however i could not prove this,
having lost the logfiles.
After reading several of those posts here and on openafs-devel, i am now pretty sure
that i
suffered from the same bug, because apart from the missing logfile entry, the behaviour
on my box was pretty much the same as reported by Marco Foglia in
<[EMAIL PROTECTED]>
and Matthew N. Andrews in <[EMAIL PROTECTED]> on the
openafs-devel
list.
Especially since the first report from Marco Foglia dates back to 10/31/2001, and i
intend
to use openafs on my home box and at work in a minor installation, which might serve as
a testbed for a larger installation lateron, i'd prefer not to wait for a fix, but
rather
like to know which workaround seems viable, especially if you want to have regular
backups...
If i fail to resolve this issue, i'd have to decide not to use afs, since regular
lossage
of this dimension is clearly not desirable. ;-)
>From the other posts, i noticed a few points which might be helpful:
- Don't use backup volumes. Marco Foglia clearly stated that the problem never
arises when the backup volumes are removed.
This probably means that in a smaller installation i will take regular dumps
directly from the home volumes, instead of using the backup volumes. Are
there
any negative side-effects to be expected, i.e. because a mail delivery
process
might hang in iowait for a long time, processes might timeout, etc.?
- I can't see clearly whether using a single threaded fileserver (is this the
same as the lwp fileserver?) will help. Several posters hinted in this
direction
but [EMAIL PROTECTED] in <[EMAIL PROTECTED]>
stated
that it might make things worse.
What else could help me get around the problem, whilst retaining most of afs's
functionality?
Best Regards
