Hi<br>
<br>
In our case the unify volume appears completly empty altough the<br>
disks have data, also the server log shows some lines about activating<br>
auto-heal but nothing happens, so we have build a script to populate<br>
the namespace, in our case we have a folder that contains a subfolder<br>
named 'namespace' and 6 subfolders named 1 to 6 where each one is a<br>
brick of the unify volume, then running this on the main folder<br>
populates the namespace and creates appropiate folders in all bricks:<br>
<br>
#!/bin/bash<br>
<br>
for disk in 1 2 3 4 5 6 ; do<br>
for file in `find $disk`; do<br>
rel=${file#*/}<br>
if test -d $file ; then<br>
mkdir -p namespace/$rel<br>
for dsk in 1 2 3 4 5 6 ; do<br>
mkdir -p $dsk/$rel<br>
done<br>
else<br>
touch --reference=$file namespace/$rel<br>
fi<br>
done<br>
done<br>
<br>

Hi<br>
<br>
We have a similar problem. Our file system became unusable for some reason. It seems to me like GlusterFS believes that files are present on some nodes when they really are not. I want to try to regenerate the namespace from the data that is actually present on the nodes.<br>
<br>
Does anyone have information about how that can be achieved? Somewhere I read that:<br>
<br>
Namespace does not hold any crucial data, it is just like a cache. Infact you can wipe our your namespace anytime and it will rebuild again.<br>
<br>
Thanks for your help<br>

Hi<br>
<br>
i have setup a unify volume using glusterfs 2.0.1 using several<br>
disks with existing data, but once mounted in the remote client<br>
the volume appears empty where it was suposed to auto-heal it's<br>
contents automatically, is there any way to automatically<br>
generate the namespace so existing data is visible to clients ?<br>
<br>
-- Thanx & best regards ...<br>
