Re: [Moosefs-users] Strange chunk of goal 0, 1 copy

[Michal B. <mic...@ge...>]

Hi Leonid!

This is normal. This is a way to mark chunks belonging to the non-existing
files (i.e. deleted ones). Deleting of files is done asynchronously in
MooseFS. First a file is removed from metadata and its chunks are marked as
unnecessary (goal=0). Later the chunks are removed in an "idle" time. This
is much more effective than to erase everything in the moment of deleting
the file.


Regards
Michal

Subject: [Moosefs-users] Strange chunk of goal 0, 1 copy

Greetings, everyone!
Recently while experementing with MooseFS 1.6.19 on FreeBSD 7.2 I came to
the following strange state:
Web interface shows me that there is 1 copy of a chunk of goal 0.
What is the chunk?...
I have only files in the root directory of the MooseFS.

% sudo mfsfileinfo /mnt/mfs_test/* | grep chunk | wc -l
      16
So, these are 16 chunks of goal 2 which web interface correctly shows me.
Where the strage "17th chunk" comes from (All FS objects = 17)? Why has it
goal 0?...
How can I figure it out?...
-------------------------------------
Gzipped metadata.mfs.back is in attachments.
I'w greatly appreciate any help on the subject.
Best regards, Leonid.
