cache_purge: shake on cache 0x5880a0 left 8 nodes!?

[Paul Slootman <paul@wurtel.net>]

Hi,

I had problems due to the well-known endian bug.
I first ran xfs_repair on it from the standard Debian package,
version 2.6.20.  That gave a lot of output (which can be found at
http://www.xs4all.nl/~wurtel2/xfs_repair.out.4 ).

While that was running, I got today's CVS version and built that
(it reports version 2.8.11).  I ran that version against the
just-repaired filesystem, and got a number of additional errors,
notably:

empty data block 10 in directory inode 1343747104: junking block
empty data block 11 in directory inode 1343747104: junking block
empty data block 12 in directory inode 1343747104: junking block
free block 16777216 entry 10 for directory ino 1343747104 bad
rebuilding directory inode 1343747104

This 7 times; additionally, this was mentioned a couple of times:

cache_purge: shake on cache 0x5880a0 left 8 nodes!?

In fact, twice before the final "done.".

The second repair output can be found at
http://www.xs4all.nl/~wurtel2/xfs_repair.out.4b .

Should I be worried about that?  I tried a search for "shake on cache"
and found zero hits...

Additionally, the hash hit rates seem pretty bad. Anything to be
worried about, and could anything be done about it?


thanks,
