<DIV><FONT face=Arial size=2>I have some basic lustre questunes wich i didnt get
answares from lustre official maulals</FONT></DIV>
<DIV><FONT face=Arial size=2>and think maybee people here allready run into
some of those issues and can be of help .</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Asuming an OST is gone and a new server (new
install need to replcace it) </FONT></DIV>
<DIV><FONT face=Arial size=2>On my tests after formating the new OTS with
--index=0002 for example</FONT></DIV>
<DIV><FONT face=Arial size=2>when trying to mount it it cant / error code say
that this OST index id allready in use</FONT></DIV>
<DIV><FONT face=Arial size=2>so i may missing a procedure maybee on the MDT
etc..</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- I tested the dump/restore utility wich suppose to
make a minimal dump including the EA of file systems</FONT></DIV>
<DIV><FONT face=Arial size=2>the MDT is dumping ok but on the OST it say that
the file system isnt supported</FONT></DIV>
<DIV><FONT face=Arial size=2>I just explore all options of backing up a single
OST/MDT drives including LVM backup</FONT></DIV>
<DIV><FONT face=Arial size=2>but the dump/restore looks better seens its backing
up only the data rather then the entire drive</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Just want to make sure that the default policy(if
not mentioned otherwise on the format) is not to stipe files</FONT></DIV>
<DIV><FONT face=Arial size=2>My tests show that this is the case but i just want
to make sure</FONT></DIV>
<DIV><FONT face=Arial size=2>If soo where is the --param="lov.stripe.count=...."
need to come ? OST's or MDT</FONT></DIV>
<DIV><FONT face=Arial size=2>on MDT for example its making the MDT
unmoutables</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- If i want to stripe a single file i need to
create it first (not existing file) so if i create it with a stripe policy then
how can</FONT></DIV>
<DIV><FONT face=Arial size=2>i use the real file with this policy , will
overwrite the file with the real file will work ?</FONT></DIV>
