Error description

• In the event an out of space condition at the operating system,
  the FlashCopy Manager local snapshot database can be corrupted
  and lost.  This out of space condition is against the drive on
  which the adsm.sys\vss_staging folder is stored (by default this
  is the system drive).
  
  The initial out of space issue will exhibit the following
  failure during a backup:
  
   FMV1768E TSM was unable to find space for a new snapshot.
     FCM function name : vssInitBackupSpec
     FCM function      : No Space available for new backup.
     FCM return code   : 115
     FCM file          : ..\..\common\winnt\vssback.cpp (1604)
  
  The failure can result in the corruption of the local snapshot
  database.  The next attempt to use the local snapshot database
  will detect the corruption, but will fail to recover from the
  saved copies even though those copies are present.  Further
  backup attempts will result in FMV1236E (RC115) and FMX5060E API
  failures.  The restore tab will no longer show historical
  backups available for restore.  The following additional entries
  may be present in the dsmerror.log:
  
    cuGetBackQryResp: Server aborted txn, reason: 255
    FMV5250E An unexpected error was encountered.
     FCM function name : vssQueryBackup
     FCM function      : cuGetBackQryResp() returned '255'
     FCM return code   : 255
     FCM file          : ..\..\common\winnt\vssquery.cpp (964)
  
  Versions Affected: FlashCopy Manager 3.1, 3.2, and 4.1 on
  Microsoft Windows
  
  Customer/L2 Diagnostics: A trace of the backup attempt will show
  the following entries confirming that the database is corrupt:
  [020660] [12804] : ..\..\common\vs\fmdb.cpp( 391):
   fmDbReadCtrlRec(): Reading cacheObject control record for db
   file
   C:\adsm.sys\vss_staging\.TsmFmDatabases\TsmFm__<NODENAME>_0000.

  [020660] [12804] : ..\..\common\vs\fmdb.cpp( 522):
   fmDbReadCtrlRec(): corrupt database detected .
  
  The recovery phase then starts and fails to recover the
  database.  This indicates that the database has not been saved,
  however review of the vss_staging shows there are copies (these
  are listed with a .saveDb extension):
  [020660] [12804] : ..\..\common\vs\fmdb.cpp( 182):
   fmDbCheckRecovery(): corrupt database detected.
