I'm repeating my posting of July 20th below, since there were no comments
last time.
Are "unknown stream type 15" and "this should not happen" an expectable
behaviour due to Linux ACLs or related to something else?


**1** While rebuilding the catalog with bscan, I'm getting a huge number of
messages like this:

bscan: bscan.c:735 Unknown stream type!!! stream=15 data=user::rwx
group::rw-
other::r--

In the beginnging, bscan was running nicely for a while. Then bconsole
screen started scrolling with these messages, no idea about how many there
were. Tens of thousands maybe, but I guess it's irrelevant. The whole backup
was appr. 160000 files.

Could this be related to linux ACLs ? Does bscan possibly get confused with
them?
The backup in question is a full backup from a file server, and the largest
partition had quotas and acls enabled.
While running the original backup, there was "aclsupport = yes" in the
fileset options.


**2** Before running the bscan, I also ran bextract with the same tape, and
it looks to me that those few files that had acls in use, had obviously lost
all acl information. At that time there also were messages that mentioned
"stream=15" and something like "this should not happen". I have no idea
about how many that kind of messages there were during bextract run, since I
just saw the final screen. Unfortunately I don't have the exact message from
bextract available.


Bacula version is 1.38.11-3, self-built from source rpm.
FC5 & MySQL, Exabyte VXA-320 Autoloader.
Backup was written with the same version of Bacula, but on FC4.

At least at this time this isn't an urgent issue. The only real problem I
know so far were the lost acls, and they were nothing important yet (but may
be at the next time) but mostly related to some experiments.
Mostly I'm just curious to know why software keeps saying "this should not
happen"...

Btw, a regular restore that was based on the rebuilt catalog finished right
now. It seems to have been able restore the acls too. Looks that bextract /
bscan don't support acls. Actually, I wouldn't be surprised if that's also
documented somewhere in the "Bacula Bible", but I just couldn't find it
there...


Regards,
Timo
