Re: Safely mount OS X UFS filesystem?

2007-07-07 Thread nawcom
Oh god i apologize for the unacceptable asnwer; i was probably 
half-asleep when i responded previously :-P


yes, theres no support as far as i know for darwin ufs for freebsd, from 
what i understand darwin ufs is gonna be the next filesystem for apple 
to ditch, and for 10.5 they will be using sun's zfs filesystem. theres 
also development going on for zfs support in the freebsd kernel.


the only thing ive done before in a situation like this is to backup the 
data (copy to alt disk) on the ufs, delete the ufs filesystem and 
replace it with hfs+ and restore the backup back onto it - assuming you 
didnt plan for that ufs partition to be bootable or anything. hfs+ is 
supported in freebsd.


I hope that's a more reasonable suggestion - looks like the coffee 
helped :-P

4k blocks and 1k fragments, and a few minor oddities in their layout;
they are pretty much exactly the UFS NeXT used on their workstations.

If so, Will such a filesystem be safe to mount under OS X after I use it
on FreeBSD?

I seem to be able to mount these under NetBSD though the snapshot code
complains that inodes 64 and 16384 are not dedicated to snapshots.

I've mounted OS X formatted UFS file systems just fine for quite some  
time.  I haven't been able to mount FreeBSD formatted UFS  
filesystems, however.

i usually use the ufstype=openstep for darwin ufs filesystems, they seem 
to work just fine.

That's a Linux mount option, isn't it?  I was asking about FreeBSD.
