Is that 0? 32? Anyways, that's just a sidebar. One of the other disks that failed this week (my laptop drive) is less sick and the dump succeeded. I now have a 50 gig dump file. Good. Now I have a machine that's been in production in my home network for a year or two ... and for this project I added a 250G drive. The 250G drive contains a single partiton and I formatted it UFS 2 with a 65536 blocksize and a 8192 frag size. I intend to put big files on this disk. Anyways, I created a directory on that disk (which also contained the filesystem images and dumps ... about 120G in 5 large files), cd'd into that directory and ran 'restore -rvf ../dumpfile'. This went along creating directories for awhile and then it stopped for a few momments ... then sputtered along for another few seconds and then hung. The other disks on the machine were also hung when I tried to access them in the shell. I rebooted, waited for the background fscks to complete and tried again. It appears to be repeatable. The disk that I'm restoreing is a typical laptop /usr ... it has /usr/ports and /usr/src (many directories). Dave.
