Trouble matching <client> to <catalog>, error -1,124

[Nigel Smith]

All,

 

Another variant on the "-1,124 ( invalid NTFS data)" error. Anyone seen this before?

 

Setup: Xserve running OS X 10.7.5 and Retrospect Server 11.5.3 (103) backing up a variety of Mac and Windows clients to a Disk Media Set stored on an attached Xsan volume. Using both Scheduled and Proactive scripts, all to the same media set.

 

Everything ran fine for the first week, but now the Mac clients are all throwing "!Trouble matching <client> to <catalog>, error -1,124 ( invalid NTFS data)". Windows clients are backing up as before. The Xserve and Xsan both pass volume  consistancy checks, as do all the clients I've checked. Failing Mac clients can also be backed up to a new Disk Media Set on the same SAN without problem and without re-registering with Retrospect or even a restart.

 

The only thing I can think of that changed over the weekend was that Retrospect bumped into what I assume is an 8TB volume limit for its Disk Media Set function -- despite more than 50TB of free space, there was a "New Media" request which was satisfied by simply pointing it to the SAN and letting it create a second directory.

 

I can't believe that Mac clients can't cope with multi-disk Disk Media Sets -- that would be all over the Forum! And also something that, surely, the server and not the client mediates. So what *is* going on here?

(Change in Activity Thread number is me triggering a schedule manually to instantly test another previously-failed machine with a fresh set).
