Hi, thanks for respose.
As this is close-source mailserver (CommuniGate pro), I can't say 100% answer,
but the writes that I see that take too much time (15-30secs) are writes from
temp queue to final storage, and from my understanding, they are sync so the
queue manager can guarantee they are on solid storage.
Apart from that however the interactive access to mailstore modifies filenames
( read/opened/deleted flags are part of filename for each file) a lot content
of files is not changed any more. Also moves abetween directories and deletions
are only dir operations ( don't know whether sync or not - you know OS
internals better).
From description of the error you mentioned, and also
6440499 zil should avoid txg_wait_synced() and use dmu_sync() to issue parallel
IOs when fsyncing
I think that this may be also my case.
So my question is: I run Sol10U2, is there a way to quicky test new ZFS,
without reinstalling whole system?
Please say there is....
Ivan,
Patches with the bug fixes should become available in couple of weeks.
We will let you know as soon as they are available.
