[Moosefs-users] how to clean "reserved files"

[Fyodor U. <uf...@uf...>]

Hi!

I have one file in "reserved". The documentation says: "Beside the trash 
and trash/undel directories MFSMETA holds a third directory reserved 
with files intended for final removal, but still open. These files will 
be erased and their data will be deleted immediately after the last user 
closes them".

But no one user not have opened this file. Moreover, all users unmounted 
mfs share.

How to clean "reserved files"?

WBR,
     Fyodor.

I already had the same issue : Restarting mfsmaster solved the problem.

Unfortunately, restarting mfsmaster has not helped to me. :(

Hi!

I'm still about "reserved files".

Studying the sources I have come to the conclusion that the only way to 
delete this file - add a line "PURGE" to "changelog" file and execute 
"mfsmetarestore".

Has anyone made this?

WBR,
     Fyodor.

Hi

These files should eventually got deleted (and without restarting the
master). If you want to speed the process just remounting the folder should
help. Files can be "reserved" for even two weeks.

Hm. If I understand the source: If for any reason the client did not 
send (or master did not handle) CUTOMA_FUSE_PURGE - file will forever 
remain in reserved.

Question to developers - am I right or am I not watching closely the source?

WBR,
     Fyodor.
