Description
The client reported that after the failure MCS cluster went into read-only mode. Here is the UM log excerpt:

The failed operation left systemFiles/dbrm/DMLLog_$txnid_1 file behind and got the cluster into read-only mode. Moreover this file called for DMLProc rollback at the cluster start so MCS reboot didn't help.
CS should either create the file after it gets enough space in VB or remove the file in case of a failure.
