Hello, I have found, that ocfs2 is very slow when doing I/O operation without cache. See a simple test: ng-vvv1:~# dd if=/data/verejna/dd-1G bs=1k | dd of=/dev/null 1048576+0 records in 1048576+0 records out 1073741824 bytes (1.1 GB) copied, 395.183 s, 2.7 MB/s 2097152+0 records in 2097152+0 records out 1073741824 bytes (1.1 GB) copied, 395.184 s, 2.7 MB/s The underlying block device is quite

We just updated our configuratiosn to have multiple NIS servers, when we initiated a test of client failover, we were disapointed. It seemed that the only way to get a filaover was to /etc/init.d/ypbind restart.
