Subject Fwd: [jira] [Created] (CLOUDSTACK-7003) Arithmetic exception while creating a vdi on nfs volume in managed storage.
Date Fri, 27 Jun 2014 06:32:49 GMT
hi mike,

can you take a look at this logic, today i met an arithmetic exception(/ by
0) while creating a nfs volume.
any suggestions to calculate the maxNumberOfTries if the unavailableSrSpace
is equal to zero.

thanks

----------------------------------

             Summary: Arithmetic exception while creating a vdi on nfs
volume in managed storage.
                 Key: CLOUDSTACK-7003
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7003
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the
default.)
          Components: Management Server
    Affects Versions: 4.5.0
            Reporter: punith


it seems we have a bug while creating a nfs disk on managed storage,

file - CitrixResourceBase.java
api - createVdi

long unavailableSrSpace = sr.getPhysicalUtilisation(conn);

6216    long maxNumberOfTries = (totalSrSpace / unavailableSrSpace >= 1) ?
(totalSrSpace / unavailableSrSpace) : 1;

since while creation nfs disk does not have a meta data written on it like
in iscsi , unavailableSrSpace might turn out to be 0(zero), hence throwing
an divide bt zero exception.
sometimes the unavailable
