Hi ,=20
I have observed the following on SuSE 9 sp2
vcslinux25:~ # uname -a
Linux vcslinux25 2.6.5-7.187-default #1 Tue =20
Jun 21 14:03:10 UTC 2005 i686 i686 i386=20
GNU/Linux
=20
Server notifies client.
client tries to reclaim lock.
But if servers ip goes down due to
some reason , client gives error
"failed to reclaim lock".
Shouldn't lockd retry to reclaim lock.
On RedHat , lockd retries while on=20
SuSE it doesnt.
It seems that on SuSE 9 sp2 , client
gets error EIO while on RHEL4 , client gets
ETIMEDOUT and hence retries
(Shouldnt rpc call return ETIMEDOUT even on=20
SuSE?).
=20
Which is the correct behavior ?
Or is the implementation dependent?
