This works fine except when there is a hard-link to the file being renamed to the target file. In this case the reading thread hits file not found errors (not always but often). This seems to break the sped for 'rename'. The test is: #!/bin/bash touch target; for ((i=0; i &lt; 1000; i=i+1)); do echo "snafu$i" &gt; $1/file$i; ln $1/file$i $1/link$i mv -f $1/file$i $1/target; done; and the reading side: #!/bin/bash while(true);do cat $1/target; done if the linking step is removed from the writing thread, then no errors are seen as expected.

Ext4 has superblock fields to store RAID 5 parameters, but the code to fully take advantage of those RAID parameters is not fully implemented. You should also take a look at your RAID parameters. If your RAID stripe size is too large, it will impact workloads such as mail servers which typically involve small writes. Have you considered using RAID 10 over RAID 5? It's not as efficient from a space perspective but if you are primarily concerned about throughput and latency, it's the way to go. - Ted </pre> Ted Ts'o 2011-09-29T13:08:32 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.file-systems.ext3.user
