Re: [Gluster-devel] Rsync failure problem

[skimber]

Further to my message below, I'm getting a lot (thousands?) of errors like
this in the glusterfsd server log:

2008-07-15 14:19:41 E [posix.c:1984:posix_setdents] brick-ns: Error creating
file /data/export-ns/mydata/myfile.txt with mode (0100644)

Nothing relevant in syslog or the client logs I don't think.
