Subject: [2.6.0-test4] blocking access to mounted scsi devices
Date: Mon, 25 Aug 2003 17:04:53 +1000	[thread overview]
Message-ID: <3F49B515.6010107@torque.net> (raw)

A recent test of smartmontools on lk 2.6.0-test4 failed
miserably on my main SCSI disk. It would seem that
attempts to use either the:
    SCSI_IOCTL_SEND_COMMAND
    SG_IO
ioctls on a mounted SCSI "block" device fail with EBUSY.
These ioctls work fine on devices that don't have mounted
file systems on then. If this is a new policy then it needs
to be reconsidered. smartmontools still works ok on ATA disks
in lk 2.6.0-test4.

Both the ioctls in question still work via the corresponding
scsi generic device. Will scsi generic devices make a
re-appearance in sysfs (as indicated by Christoph when the
relevant code in sg was removed)?
