The statement is still valid for for both ext3 and ext4. Using barrier=1 may also affect disk speed, but I suspect that's more theoretical than noticeable. There are other options that may be useful that we don't mention. For example noatime,discard,data=writeback is useful for ssd drives. Perhaps a more general statement about mount options would be more appropriate than a mention of just barrier. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
