God, this is so damn useful to know! Thanks a ton for showing this.
Too bad we can't have Bacula do this translation for us and log it,
along with the original error code just in case. That would be a
huge help for people debugging prblems like this.
Luc> C:\>net helpmsg 8
Luc> Not enough storage is available to process this command.
Luc> Some other common ones:
Luc> C:\>net helpmsg 3
Luc> The system cannot find the path specified.
Luc> C:\>net helpmsg 5
Luc> Access is denied.
Luc> The upper part - 0x8007 - gives info about where the error originated, and
the sort of message (first digit 8 or C = error), but there's no such way to
quickly decode it at a command prompt.

Luc> Subject: [Bacula-users] Shadow Copy issue - Fatal error: VssOject is NULL
Luc> I have been running the same version of Bacula on a Windows 2k12 server
for over a year (5.2.10). A few weeks ago, we started getting all our jobs
failing over the weekend due to an apparent issue with VSS. Has anyone
encountered the following fatal error:
Luc> 20-Apr 19:30 bacula-zha JobId 5546: Start Backup JobId 5546,
Job=Software_Share_Backup_-_Encrypted.2015-04-20_19.30.00_41
Luc> 20-Apr 19:30 bacula-zha JobId 5546: Using Device "FileStorage-software" to
write.
Luc> 20-Apr 19:30 bacula-zha JobId 5546: Sending Accurate information.
Luc> 20-Apr 19:30 bacula-sd JobId 5546: Volume "zha-software-encrypted-vol0360"
previously written, moving to end of data.
Luc> 20-Apr 19:30 bacula-sd JobId 5546: Ready to append to end of Volume
"zha-software-encrypted-vol0360" size=1775302040
Luc> 20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS API failure calling
"CoInitialize". ERR=Unexpected error. The error code is logged in the error log
file.
Luc> 20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS was not initialized
properly. ERR=Cannot create a file when that file already exists.
Luc> 20-Apr 19:30 fs01 JobId 5546: Fatal error: VssOject is NULL.
Luc> 20-Apr 19:30 bacula-sd JobId 5546: Elapsed time=00:00:06, Transfer rate=0
Bytes/second
Luc> 20-Apr 19:30 bacula-zha JobId 5546: Error: Bacula bacula-zha 5.2.13
(19Jan13):
Luc> The only way to "fix" this is to reboot the client. Items I have tried:
Luc> * Restarted the Bacula service on the client - backups still failed
Luc> * Tested connection to client using the 'estimate' command, success. Issue
isolated to Windows server.
Luc> * List current VSS instances via cmd prompt (vssadmin list writers) - All
states reported as Stable / No writers reporting errors
Luc> * Manually create a shadow copy on the client (vssadmin create shadow
/for=e: ) and then manually remove all shadow copies (vssadmin delete shadows
/all) - backup still fails
Luc> * Ran System File Checker (sfc /scannow) - No issues found, backups still
fail
Luc> After rebooting the client, backups using VSS work fine for a few days and
then start failing with the same FATAL error. It is not always the same job
that fails first.
Luc> On the client, these entries are logged in C:\Program
Files\Bacula\working\zhfs01.trace
Luc> fs01: vss_generic.cpp:366-0 VSSClientGeneric::Initialize: CoInitialize
returned 0x80070008
Luc> If anyone has any ideas on how to further troubleshoot this issue, or have
encountered this before, I'd greatly appreciate it.[/img]
