Re: [Networker] Corrupt compressed (.bz2) file restores.

Are you sure its not what you are restoring to that is the problem?
Does it make a difference if you say restore them to /tmp or a non-CX disk?

Greetings, Have an interesting (if somewhat rather bizarre) issue.
Environment: RHEL 4.*, Networker Server 7.3.3. File system sets on a
Celerra/Clariion (CX700) combo.
User lets me know that he accidently partially deleted a subdirectly
containing many files. Not all of the files were deleted but that's not
relevent to this. I copied his old directory to a directoryname.orig. And
just restored the whole thing again, rather than trying to figure out what
had actually been deleted.
The user came back a day (or so) later and gave me a list of
553 "blast.bz2" files that were corrupted after my restore. In digging
into this and using bunzip2, I saw where some were indeed corrupt. And, I
could do some selective restores of a few and saw where they were not
corrupt.
How this has to do with Network, is that say I have a list of 100 of these
blast.bz2 files. I would put those in a file and have Networker do the
restore. When the restore finished, I would then do bunzip2 on each one,
and maybe 40-50 of 100 would be fine, while 50-60 would be corrupt. I then
would take the remaining that were corrupt, but them through recover
again, and then time maybe another 20-30 would be fine, etc. I would do
this until I got down to a single corrupted blast.bz2 file and then I
would be fine after another recover.
All of the data is being restored from the same exact SSID.
So why wouldn't the good files be restored the first time I tried it?
We've check for errors in the file system, and haven't found anything yet.
Thanks,
Randy
