[Gluster-devel] cp taking 100% cpu and never terminating

[Mickey Mazarick]

Heh yes sorry on the server side I'm seeing errors like:
2008-05-11 17:02:22 E [posix.c:1982:posix_setdents] system-ns: Error 
creating file /mnt/gluster/system-ns/scripts/drbl/drblupdateusr.sh with

.
The times don't correspond to the errors on the client. This is from the 
storage brick "system1" mentioned in the client logs below.

Thanks!
