Upload freeze when no 'keep' chunkservers available

[struthio]

Hi,

I think I found incorrect behavior in moosefs. I will explain it on example. For test I used 2 chunk servers and 1 master.
Label A - Chunk server 1
Label B - Chunk server 2

I created SC Class with definition:
Mode - Strict
Create - A
Keep - B
Archive - B

Next I have file around 2GB.

Scenario 1: Both chunk server online - Everything works fine.
Scenario 2: Only chunk server A is online.
In this scenario when I upload file to MFS it goes till around 15% then hangs - and stays that way (no uploading is done).
If I start chunk server 'B' while transfer is hanging, everything starts and upload continues as nothing happened.

Shouldn't this be that in absence of 'B' file is successfully uploaded to 'A' (as this is the 'Create' class). After file (or chunk) is on A, SC class of file is changed to B, and redistributed internally in MFS ?

I mean shouldn't client receive confirmation that 'file is uploaded' after it is successfully transferred to 'Create (A)' chunk server ?

Thank you for that report. It's not an expected behaviour, we will run tests to confirm/resolve this issue.
