[pve-devel] pve-storage: add Glusterfs Plugin

[Alexandre DERUMIER]

Oh, I found 2 interesting volume options ! 

cluster.data-self-heal-algorithm  (default reset)

Selects between "full", "diff", and “reset”. The "full" algorithm copies the entire file from source to sinks. The "diff" algorithm copies to sinks only those blocks whose checksums don't match with those of source. Reset uses a heuristic model. If the file does not exist on one of the subvolumes, or a zero-byte file exists (created by entry self-heal) the entire content has to be copied anyway, so there is no benefit from using the "diff" algorithm. If the file size is about the same as page size, the entire file can be read and written with a few operations, which will be faster than "diff" which has to read checksums and then read and write.


cluster.self-heal-window-size	  (default 16)

Specifies the maximum number of blocks per file on which self-heal would happen simultaneously.	



maybe cluster.data-self-heal-algorithm = diff could help ?

Not sure we can have the progress. 

We can only see files which need to be repair

That does not really display any useful info (progress).
