Re: NFS mount backup failing after upgrading to 6.2.2



We've seen the same problem with the Linux 6.2.2.0 client (with the
server(s) at these levels: 6.2.2.0, 6.2.1.0, 5.5.1.1). Same results with
64 bit and 32 client and with SSL enabled or not.

The client reports this from dsmc:

tsm> i /some/nfsmounted/filesystem

Incremental backup of volume '/some/nfsmounted/filesystem'
ANS1228E Sending of object '/some/nfsmounted/filesystem' failed
ANS4021E Error processing '/some/nfsmounted/filesystem': file system not
ready
ANS1802E Incremental backup of '/some/nfsmounted/filesystem' finished
with 1 failure

... and this in the error log:

01/06/2011 14:54:33 ANS3417W nfsd: A system call psCollectMountTableInfo
failed with code 6201 - Invalid server name. Need format 'server:/volume'.

01/06/2011 14:54:33 ANS3402W psGetHostName(): A system call
gethostbyaddr() failed with code 1.
01/06/2011 14:54:33 ANS5250E An unexpected error was encountered.
    TSM function name : nsGetNasVolumeInfo():
    TSM function      : dmMapNfsVolume() failed to map remote volume for
path: </some/nfsmounted/filesystem>.

    TSM return code   : 6201
    TSM file          : snapcommon.cpp (378)
01/06/2011 14:54:34 ANS1228E Sending of object
'/some/nfsmounted/filesystem/*' failed
01/06/2011 14:54:34 ANS4021E Error processing
'/some/nfsmounted/filesystem/*': file system not ready
01/06/2011 14:54:34 ANS1802E Incremental backup of
'/some/nfsmounted/filesystem/*' finished with 1 failure


With everything identical (dsm.sys, dsm.opt, NFS mount parameters,
paths) and the client at 6.2.1.1 the NFS backups work perfectly.

Haven't got around to contacting IBM yet.
