Re: [Bacula-users] Is Truncate just broken?

[Kern Sibbald]

Hello Shon

Well, maybe the Solaris NFS has additional quirks that we have not yet 
identified.
In any case, we have not changed the code concerning file truncation for 
quite

a few years as far as I can remember.

Good luck on finding the problem(s) ...

Hello,

ftruncate did not seem to work over NFS or at least on certain

fstat) is non-zero, Bacula will delete and recreate the Volume. 
This is not

ideal, because it may create it with different permissions and/or
owner,
group but it seemed to work.  If you drop the SD's user from root to
bacula, depending on how you have defined your NFS volume permissions,
the SD may be unable do the delete and recreate.

Nothing has changed in that code for many years.

happened in more recent Bacula versions that changed this again.

It is working fine, automatic or manually. I use it on a lot
of Bacula deployments without problems.

I'm looking forward to see a message that shows under which circumstance
truncate doesn't do what was expect. Mostly for the follow-up messages
that say how truncate in Bacula work.
