L.S.,It is not possible, at least I am not aware about any such solution yet.
I was wondering if it would be possible to turn an existing filesystem with data
(ext4 with files en dirs) into a GlusterFS brick ?
you are right !
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 ?
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.
No, it is possible. You just need to be a bit creative.
Could you let me know how many such bricks you have which you want to convert to glusterfs. It seems like you want replication as well. So if you give me all this information. With your help may be we can at least come up with a document on how this can be done.
Thanks,
Saravana
