Re: How to drop an inconsistant chunk?

I had to drop a chunk "manually" once by editing the CHUNK PAGE in the reserved pages. What you need to do is zero out the chunk info and move the other chunks info upwards. This was in V5.x though. I used dd to copy out the 12 reserved pages and then wrote a C (or Perl) program to edit the data. Then I used dd to write the pages back. *** BACKUP THE ROOT RAW DEVICE BEFORE STARTING *** You can use this method to bring offline chunks online in V5.
