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