Neil Brown put forth on 8/4/2010 5:24 PM: > Both page-cache and read-ahead work at the filesystem level Are you referring to /sys/block/sdx/queue/read_ahead_kb? I'm pretty sure this works below the FS level and below the partition level. This read_ahead works at the block device level. At least for individual or JBOD. Are you saying this setting gets ignored by the kernel if/when mdadm, LVM, and/or crypto are used? -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
