[Gluster-devel] What does it mean (unify bug ?) ?

[Amar S. Tumballi]

2008-06-09 11:04:49 E [posix.c:1984:posix_setdents] backupbrick-ns: Error
creating file
/var/lib/gluster/ns//hosting/****-databases/***/databases/mysql/db_iis_enfo_en/iis_mylinks_cat.MY
with mode (0100660)
This is a wrong error level for error. The error is EEXIST, and it comes
when unify does self-heal of a directory. Fixed in tla repo, will be coming
out with new release.

Working on rsync/rdiff creating multiple files. Yet to corner it down. Will
have 1.3.10 with this fix this week.

Thanks for the report, we will try to reproduce it locally.
