Re: Convert existing volume to shard volume

[Krutika Dhananjay <kdhananj@xxxxxxxxxx>]

If you want the existing files in your volume to get sharded, you would need to

a. enable sharding on the volume and configure block size, both of which you have already done,

b. cp the file(s) into the same volume with temporary names

c. once done, you can rename the temporary paths back to their old names.

Hi List,

i just upgraded from 3.5.8 to 3.7.8 and want to convert my existing VM
Images volume to a shard volume now:

gluster volume set dis-rep features.shard on
gluster volume set dis-rep features.shard-block-size 16MB

How are the existing image files handled?
Do i need to start rebalance to convert existing files?

Or is it better to start with an empty volume?
If so, why?
