The last of the ICMS backbone servers were upgraded today to use the ext4 filesystem. Prelimilary testing shows that the time required to perform fsck’s has been reduced by almost 90% across the service. All servers will need to run a full filesystem check to reduce the time of subsequent checks. Many servers performed this during the last maintenance period and are already optimized. This process will be completed during the next 48 hours. Moving to ext4 will offer some other minor performance improvements as well.
