[Gluster-users] intresting issue of replication and self-heal

[Mingfan Lu]

I have a volume (distribute-replica (*3)), today i found an interesting
problem

node22 node23 and node24 are the replica-7 from client A
but the annoying thing is when I create dir or write file from client to
replica-7,

 date;dd if=/dev/zero of=49 bs=1MB count=120
Wed Jan 22 11:51:41 CST 2014
120+0 records in
120+0 records out
120000000 bytes (120 MB) copied, 1.96257 s, 61.1 MB/s

but I could only find node23 & node24 have the find
---------------
node23,node24
---------------
/mnt/xfsd/test-volume/test/49

in clientA, I use find command

I use another machine as client B, and mount the test volume (newly mounted)
to run* find /mnt/xfsd/test-volume/test/49*

from Client A, the  three nodes have the file now.

---------------
node22,node23.node24
---------------
/mnt/xfsd/test-volume/test/49

but in Client A, I delete the file /mnt/xfsd/test-volume/test/49, node22
still have the file in brick.

---------------
node22
---------------
/mnt/xfsd/test-volume/test/49

but if i delete the new created files from Client B )
my question is why node22 have no newly created/write dirs/files? I have to
use find to trigger the self-heal to fix that?

from ClientA's log, I find something like:

 I [afr-self-heal-data.c:712:afr_sh_data_fix] 0-test-volume-replicate-7: no
active sinks for performing self-heal on file /test/49

It is harmless for it is information level?

I also see something like:
[2014-01-19 10:23:48.422757] E
[afr-self-heal-entry.c:2376:afr_sh_post_nonblocking_entry_cbk]
0-test-volume-replicate-7: Non Blocking entrylks failed for
/test/video/2014/01.
