L.S.,
I was wondering if it would be possible to turn an existing filesystem
with data
(ext4 with files en dirs) into a GlusterFS brick ?
It is not possible, at least I am not aware about any such solution yet.
I can't find much info about it except the following remark at [1]
which seems
to indicate it is not possible yet:
Data import tool
Create a tool which will allow importing already existing data
in the brick
directories into the gluster volume.
This is most likely going to be a special rebalance process.
So that would mean i would always have to:
- first create an GlusterFS brick on an empty filesystem
- after that copy all the data into the mounted GlusterFS brick
- never ever copy something into the filesystem (or manipulate it
otherwise)
used as a GlusterFS brick directly (without going through a
GlusterFS client mount)
because there is no checking / healing between GlusterFS's view on the
data and the data in the
underlying brick filesystem ?
Is this a correct view ?
you are right !
Once the data is copied into Gluster, it internally creates meta-data
about data(file/dir).
Unless you copy it via Gluster mount point, it is NOT possible to create
such meta-data.
