Operating Systems Solaris Can ufsdump create files that have a .vtoc and .dmp extension? Post 302980244 by hicksd8 on Thursday 25th of August 2016 12:18:13 PM

Hmmmmmm.......not being able to ufsrestore partition0 is a bit of a show stopper.

I've been looking at the file sizes that you posted again and coming to the conclusion that your .vtoc files are in fact probably archive files (dump table-of-contents) created by using the 'a' switch on the ufsdump command. If so, these should have the suffix .dtoc in my book. Mis-named by the previous sysadmin perhaps. Such files are used by ufsrestore to determine whether a file is, or is not, in a dumpfile when the restore of one file is requested (not the whole filesystem).

So how did you come by the .dmp files? Is there anyway that they could have been corrupted? Have they been ftp'd or otherwise copied from another system? Could they have been written to tape originally and subsequently 'dd' off to disk? If so, the blocking factor could be a very low number like 10.

On you post you didn't show that you tried other blocking factors like 8192, 3072, 20480 and the like. Although unlikely, any multiple of 1024 could just work.

pspp-dump-sav(1)						    PSPP Manual 						  pspp-dump-sav(1)

NAME

       pspp-dump-sav - dissect SPSS system file

SYNOPSIS

       pspp-dump-sav [-d | --data[=maxcases]] file...
       pspp-dump-sav --help | -h
       pspp-dump-sav --version | -v

DESCRIPTION

       The  pspp-dump-sav program reads each SPSS system file file and prints its contents.  The output format is useful for debugging system file
       readers and writers and for discovering how to interpret unknown or poorly understood records.  End users may find the  output  useful  for
       providing the PSPP developers information about system files that PSPP does not accurately read.

OPTIONS

       -d[maxcases]
       --data[=maxcases]
	      By  default, pspp-dump-sav does not print any of the data in a system file, only the file headers.  Specify this option to print the
	      data as well.  If maxcases is specified, then it limits the number of cases printed.

       -h
       --help Prints a usage message on stdout and exits.

       -v
       --version
	      Prints version information on stdout and exits.

BUGS

       Some errors that prevent files from being interpreted successfully cause pspp-dump-sav to exit without reading any additional  files  given
       on the command line.

AUTHORS

       Ben Pfaff and John Darrington.
