updates - 4 replicated worked fine while testing with gnfs with qa3,qa6 and qa7 releases.with qa9, dd command works with local machine.
checked with 3.1.0qa9 with gnfs with 4 replicate ,it works.
while checking with 3.1.0qa9 without any performance translator,dd command works!
write-behind seems like causing this issue. dd worked fine without any translator -when write-behind is added ..it hangs.
with 3.1.0qa9 worked when writebehind flush-behind turned off. with 3.0.5, dd worked,with default writebehind options.
logs file can be found under /share/tickets/1448. creating 1mb file hangs . creating empty file "touch f1" works.
tested with 3.1.0qa14 ,started nfs using dvm commands, and mounted using nfs. even here dd hangs for 25mb file creation.
tested with qa24 ,dd hangs.
tested with 3.1.0qa25 ,its not yet fixed.
(In reply to comment #9) > tested with 3.1.0qa25 ,its not yet fixed. checked with 3.1.0qa26 with nfs and fuse mount dd worked.
tested again,working.after testing against qa28 and this will be moved verified.
works with qa34.
