Bug 26305

Summary: Cannnot restore partions with FreeBSD 4.x through network
Product: Base System Reporter: masaki <masaki>
Component: binAssignee: Matt Jacob <mjacob>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: 4.2-RELEASE   
Hardware: Any   
OS: Any   

Description masaki 2001-04-03 02:10:01 UTC
When trying to restore dump file (about 500MB) from other machine's
harddisk by way of network, OS (FreeBSD 4.2) always freezes.

Machine: Dell's Optiplex XMT 5133
HDD: 4.3GB IDE harddrive (Western Digital Caviar 43AA)
Memory: 16MB fastpage nonparity SIMM x 4 (64MB total)

Fix: 

If using FreeBSD 3.5.1-RELEASE, the problem never occured.
How-To-Repeat: In FreeBSD 4.2-REL's signle user mode, do (1) and (2).

(1) dump FreeBSD partition stored large size data (more than 500MB)
    onto the other machine.
    eg# dump 0af other_machine:dump.file /dev/ad0s1f

(2) restore it from the machine in signle user mode.
    eg# cd /usr; restore rfv other_machine:dump.file

And then local machine freezes.

I'll see if this is still broken.

I could not reproduce the hang. I restored over the net the entire contents 
of a /usr partition. 

It's just possible that if you restore into a live /usr partitition that 
there might be issues, but basically you shouldn't be doing that. If you 
have separate root and usr partiations, restore your usr partition to another 
directory and then remount it later as /usr.
