Indeed, my terminology is inexact. I believe you are correct; our diskless nodes use tmpfs, not ramdisk. Thanks for the clarification! On 11/4/11 11:00 AM, Rushton Martin wrote: There appears to be some confusion about ramdisks and tmpfs. A ramdisk sets aside a fixed amount of memory for its

There appears to be some confusion about ramdisks and tmpfs. A ramdisk sets aside a fixed amount of memory for its exclusive use, so that a file being written to ramdisk goes first to the cache, then to ramdisk, and may exist in both for some time. tmpfs however opens up the cache to programs so
