Hi,
I'm running 4.0-STABLE from about May 17. I have a strange situation
here; I've got two sets of two disk drives chained to my SCSI bus here
that I use for data drives. (Not currently using softupdates.) From a
df:
Filesystem 1024-blocks Used Avail Capacity Mounted on
/dev/da1s1e 4050327 3644898 81403 98% /a
/dev/da2s1e 4050327 2933727 792574 79% /b
/dev/da3s1c 17253247 158881 15714107 1% /c
/dev/da4s1c 17253247 9725925 6147063 61% /d
They're connected like this, with "-->" representing cables connecting the
boxes:
(externalbox #1) (externalbox #2)
PC --> [SCSI 3, SCSI 4] --> [SCSI 1, SCSI 2]
Oh yea, dmesg might be useful. Attached at end. Anyway, here's the
problem: When I dismount and disconnect that last box, remove it from
fstab, put terminators after externalbox #1, I find that upon reboot
FreeBSD screams mightily, says I need to do an fsck on drives 3 and 4,
and dumps me in single-user mode. OK, re-attach the box, leave it
off... and I still get wild complaints. Lastly, turn on box #2, but don't
mount the drives -- and it boots up fine!
I'm completely puzzled here. Any suggestions?
Thanks,
Brian
