Description Nir Soffer 2014-07-02 12:20:15 UTC
Description of problem:

When using jsonrpc, reconstractMaster send 8 arguemnts instead of 9 as specifed in the schema. The missing argument is the *first* one, the hostId.

The schema:

# @StoragePool.reconstructMaster:
# Recover a Storage Pool by reconstructing its Storage Domains.
# @storagepoolID:           The UUID of the Storage Pool 
# @name:                    A human-readable name for the Storage Pool 
# @masterSdUUID:            The UUID of the Storage Domain that will be used as
#                           the master domain
# @masterVersion:           The Storage Domain version of the master domain
# @domainDict:              Storage Domain statuses to be restored
# @lockRenewalIntervalSec:  The number of seconds to wait before renewing lease
#                           (Should be less than @leaseTimeSec).  0 selects the
#                           default value.
# @leaseTimeSec:            The maximum number of seconds that the leaseholder
#                           may retain the lease without renewing it.  0 selects
#                           the default value.
# @ioOpTimeoutSec:          The maximum number of seconds that an I/O operation
#                           may take to complete.  0 selects the default value.
# @leaseRetries:            The number of times to attempt lease renewal before
#                           failure.  0 selects the default value.
# Since: 4.10.0

error: reconstructMaster() takes exactly 10 arguments (9 given)

Becasue reconstract fails, data center is unusable and there
is no way to recover from this.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start reconstract flow

Comment 1 Nir Soffer 2014-07-02 12:41:51 UTC
Note: the schema is *incorrect* - the missing parameter is the hostId 
and not storagepoolID.

See vdsm/

    def reconstructMaster(self, hostId, name, masterSdUUID, masterVersion,
                          domainDict, lockRenewalIntervalSec, leaseTimeSec,
                      ioOpTimeoutSec, leaseRetries):
        lockPolicy = None   # Not used
        return self._irs.reconstructMaster(
            self._UUID, name, masterSdUUID, domainDict, masterVersion,
            lockPolicy, lockRenewalIntervalSec, leaseTimeSec, ioOpTimeoutSec,
            leaseRetries, hostId)

The pool id is is self._UUID and is not needed in this verb.

Comment 2 Petr Beňas 2014-08-06 08:31:20 UTC
Can you please provide more detailed steps to reproduce? How can one start the reconstract flow?

Comment 3 Allon Mureinik 2014-08-06 08:34:21 UTC
(In reply to Petr Beňas from comment #2)
> How can one start the reconstract flow?
1. Create a DC with two or more storage domains.
2. Move the master storage domain to maintenance - this should force the master to be reconstructed on another domain.

Comment 4 Petr Beňas 2014-08-26 13:46:58 UTC
Verified in  oVirt Engine Version: 3.5.0-0.0.master.20140821064931.gitb794d66.el6  with comment 3 steps

Comment 5 Sandro Bonazzola 2014-10-17 12:41:18 UTC
oVirt 3.5 has been released and should include the fix for this issue.
