In an effort to go through older on list bugs I'm wondering about the
relative importance of this compared to the fspool series. Shall I
assume this is dropped in favor of that?
Tks -
Hello, no, this won't be dropped.
We want Vortuozzo storage to be to one of storage pools backend's.
John
FWIW: It compiled, but failed syntax-check. Also the name "vstorage"
would seemingly be a bit too generic. I saw and thought virtual storage
not Virtuozzo Storage
At the moment we use this name while working with the
storage,
this is likely to change and I will update it as soon as the name will
be completely defined.
