Google first, ask later. I found this in the manuals:<br>
<h3 class="Head2">26.3.4 <a name="50438198_69657"></a>Fixing a Bad
LAST_ID on an OST</h3>
The procedures there spell out pretty well what I must do, so this
should be relatively straight forward. But, does this comment refer
to just this OST, or to all OST?<br>
<b class="TipNote">Note - </b><a name="50438198_pgfId-1296798"></a>The
file system must be stopped on all servers before performing this
procedure. <br>
<br>
So, is this the best approach to follow, allowing for the fact that
there is nothing at all left on the OST, or is there a better short
cut to choosing an appropriate LAST_ID?<br>
<br>
Thanks again, <br>

to completely remake a failed OST. I have done this in the past,
but this time, the disk failed in such a way that I cannot fully
get recovery information from the OST before I destroy and
recreate. In particular, I am unable to recover the LAST_ID file,
but successfully retrieved the last_rcvd and CONFIGS/* files.
<br>
<br>
mount -t ldiskfs /dev/sde /mnt/ost
<br>
pushd /mnt/ost
<br>
cd O
<br>
cd 0
<br>
cp -p LAST_ID /root/reformat/sde
<br>
<br>
The O directory exists, but it is empty. What can I do concerning
this missing LAST_ID file? I mean, I probably have something,
somewhere, from some previous recovery, but that is way, way out
of date.
<br>
<br>
My intent is to recreate this OST with the same index, and then
put it back into production. All files were moved off the OST
before reaching this state, so nothing else needs to be recovered
here.
<br>
<br>
Thanks,
