Jan 12, 2017 · A FUA command usually means the data needs to be committed to the NVM before signalling completion.. From my understanding, there is no requirement to flush the data before the FUA command to the NVM.. 1. If we have LBA0 (in Cache), LBA1(cache), LBA0 with FUA, Can LBA0 with FUA complete first and then LBA0 in Cache complete?

File systems supporting optimized Fua align SQL Server on Linux with SQL Server on Windows behavior and performance. Note: If DpoFua=0 is reported the Linux file systems revert to the write, flush behavior to support O_DSYNC. If you are unsure about the Fua support use forced flush behavior.

and REQ_FUA bits get stripped away if the queue does not advertise REQ_FLUSH or REQ_FUA support. But the REQ_FLUSH bit is also tested for when not merging requests (blk_queue_bio()) or when it comes to the elevator (blk_flush_plug_list()). So, since this patch the elevator reorders write requests on queues that do not have REQ_FLUSH or REQ_FUA set.

Mar 22, 2010 · At boot time on my new computer (eMachines 725-4250) I get 'doesn't support DPO or FUA' in reference to disabling the write cache on the main hard drive, a 250 GB SATA WD. It works, as near as I can tell. I'm just curious as to what the message means. Thanks for your attention. RandomTroll Slackware, updated to March 22 2010

Receiving message "doesn't support DPO or FUA", what does this mean? Why is disk write cache shown as disabled in "Write cache: enabled, read cache: enabled"? Receiving message "Assuming drive cache : write through", what does that mean? Do any of these messages mean there are problems with storage? Environment. Red Hat Enterprise Linux 6
