Re: How do I get /dev/sdb1 back without rebooting?

I am running udevd

/dev/sda1,2,3 are my Raid controller and my "/", swap, and "/export"
partitions.
They always mount as sdax.

My removable SATA drive, used for backup, is EXT3 and always mounts
as
/dev/sdb1.

As it transpires, the bad drive was not formated (I must have been
really tired).
It showed up in dev as /dev/sdb, with no numbers. Now it is formatted
and
mkfs.ext3'ed.

udevd finds USB drives but not SATA drives. I have to reboot for
that.
I am always sticking USB stick into the thing, I know udevd is
working.

Which brings up a question: if the operator leaved the removable
drive out of
the carriage, then reboots, the removable drive will not show up until
the next
reboot. Is the a way to rescan my SATA drives and get me back my /dev/
sdb1
without rebooting?

Many thanks,

I may have a similar problem, so you have my sympathy. The problem is so
slight that I have never tried to fix it.

I have a CD-ROM burner that is connected to a SCSI controller. If I boot my
machine with the CD-ROM burner turned on, it appears as /dev/scd0.

If I boot my machine with the CD-ROM burner turned off, it does not appear
at all. And turning it on at that point does nothing.

Perhaps your SATA drives act like my SCSI CD-ROM burner. I seldom boot my
machine, so I just leave the CD-ROM burner turned on all the time. But it is
too bad to do this, since I go for months between burning CDs.
