I believe I was told something misleading a few weeks ago and I'd like to have this officially clarified. NFS on ZFS is horrible unless you have sync = disabled. I was told this was effectively disabling the ZIL, which is of course naughty. Now I stumbled upon this tonight: > Just for the archives... sync=disabled won't disable disable the zil, > it'll disable waiting for a disk-flush on fsync etc. With a battery > backed controller cache, those flushes should go to cache, and bepretty > mich free. You end up tossing away something for nothing. Is this accurate?
