SymptomsPVC related tasks fail in PBA-S in 5 minutes after start with the following diagnostics logged in problem report and PBA-S log /var/log/hspc/hspc.log:
[2012/04/01 09:19:31] [DEBUG]  [HSPC::VZAgent::VZA25::Transport::recv_pkt] Using blocked read
As it may be seen in the example above backup of PVC container fails in PBA-S exactly in 5 minutes after PBA-S sent request to PVC server to back up the container.
CauseThe task fails in PBA-S after timeout defined in the parameter VZ_HN_READ_TIMEOUT passed if PBA-S did not receive data from PVC server. The default value of this timeout is 5 minutes.
Resolution1. Increase the value of the parameter VZ_HN_READ_TIMEOUT in the main PBA-S configuration file /etc/hspc/hspc.conf to e.g. 21600 (in seconds), it is 6 hours and it is enough in most cases. Add the parameter to the configuration file if it is absent.
2. Restart PBA-S backend after parameter was changed:
# service hspcd restart
