Delayed logging will dramatically decrease IOPs to the log device via cleverly discarding duplicate metadata write operations and other tricks. Enabling it may solve your problem given your high metadata workload. Delayed logging design document: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/filesystems/xfs-delayed-logging-design.txt Delaylog was an optional mount option from 2.6.35 to 2.6.38. In 2.6.39 and up it is the default. Give it a go. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
