NFS Eager Write

[Mauro Ferraro - G2K Hosting <mf...@g2khosting.com>]

Hi all, how are you?

we have been seeing that NFS has an eager write option to get better 
performance. Did someone test it in Cloudstack with QCOW2 ?.

What cons could be in this.

Thanks!

Hi,

The pros and cons of eager writes are not really related to ACS. I've personally used it when I needed high IOPS with NFS with data which I had a copy of.

NFS eager writes can be quite risky as it acknowledges write requests before data is written to disk. If the server crashes or loses power, any data in memory might be lost, leading to possible corruption.

Cheers
Alex
