After McKusick's notice of change: Message-ID: <200211250511.gAP5BU59067794@beastie.mckusick.com> for 26 Nov, I installed the kernel and world sliced at 1200 GMT 27 Nov. As a matter of principle, I _always_ run fsck -y from single user at reboot of a new world (which means every day now) even though I have not had a crash --pardon me for too many years of BSD, but habits stick da1a was shredded; only lost+found: p1:da1a #535-> ll lost+found/ total 8 0 br-xrw--wT 1 root wheel 0, 0 Jan 1 1970 #00455 0 br-xrw--wT 1 root wheel 0, 0 Jan 1 1970 #00561 0 br-xr-xr-x 1 root wheel 0, 0 Jan 1 1970 #00813 0 br-xr-x--t 1 root wheel 0, 0 Jan 1 1970 #00865 8 d-wSr-x--T 2 root wheel 8192 Jan 1 1970 #01031 The directory is empty. No pipers for Last Post, but a rather good sendoff of 80MB to bit heaven. No other partition even whimpered.... and nothing really lost since it was a duplicate of da0a. I was about to convert the remaining 9 partitions to UFS-2 when I read Kirk's notice and decided to wait. I'll rebuild the da1a partition with UFS-2 (new and improved version?) and see what happens tomorrow morning with the 1200 GMT 28 Nov slice. If I do a 'disklabel -B da1' (I have a pair of dangerously dedicated 9G 160 SCSIs), I presume that /boot/mbr is now the correct "new" UFS-2 boot record? My intention is to convert all parititions one-by-one, except da0a, to UFS-2, and then 'boot -s' from da1 and 'dd' da0a since the disks are siamese twins. -- Sanity is the Playground for the Unimaginative To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
