[Ocfs-users] (28552) ERROR: err=-14, Linux/ocfsmain.c, 1887 ; error in mapping iobuf; need to fail out
we are running OCFS on 2.4.21-15.0.4.ELsmp ocfs-2.4.21-EL-smp-1.0.12-1 ocfs-support-1.0.10-1 ocfs-tools-1.0.10-1 I have been deleting datafiles, more than 3 times successfully for rman duplication, from a mount point /data1 (total 191G). Last week when I tried to delete datafiles from the same directory, it did delete datafiles but did not release (reclaim) all space. It still showed that 20G of space was occupied. Log also recorded the following message error in mapping iobuf need to fail out (28552) ERROR: err=-14, Linux/ocfsmain.c, 1887 error in mapping iobuf need to fail out (28651) ERROR: err=-14, Linux/ocfsmain.c, 1887 error in mapping iobuf need to fail out (28727) ERROR: err=-14, Linux/ocfsmain.c, 1887 error in mapping iobuf need to fail out (28965) ERROR: err=-14, Linux/ocfsmain.c, 1887 Please advise.

The msgs in the message file need to be silenced in the module. These are debug messages. They have nothing to do with your problem. As far as the un-reclaimed issue goes, it may not have to do with deletes. We had a bug in 1.0.10/1.0.11 due to which space was not released during truncate. If you had been running 1.0.10/11 at some point and did some truncates, that may explain the issue. Run... fsck.ocfs -nv /dev/XXX >outfile Check the alloc_size (size on disk) and file_size (logical size) of your file entries. Look for ones with big differences. See if the numbers add up... roughly speaking.
