Hi list,

(Sorry for the length.)
I have this problem with sfdisk:

,----
> BLKRRPART: Device or resource busy

but fdisk and cfdisk report similar error:

,----
> Wrote partition table, but re-read table failed.
> Reboot to update table.

on this particular disk (IBM Deckstar 40Gb):

Doesn't matter _how_ I parition it. sfdisk:

,----
> # LC_ALL=C sfdisk -q /dev/hda < /tmp/fai/hda.sfdisk
`----

fails:

,----
> BLKRRPART: Device or resource busy
`----

I can:

,----
> # LC_ALL=C sfdisk -f -q /dev/hda < /tmp/fai/hda.sfdisk
`----

and it will do the job. But it will:

,----
> BLKRRPART: Device or resource busy
> This disk is currently in use.
`----

if I:

,----
> # LC_ALL=C sfdisk -R /dev/hda
`----

After a reboot, I can format and fsck the partitions on this particular
disk with no trouble.

I get _no_ such problems if I use another (smaller) ide-disk. I tried
Seagate and IBM.

Any idea what I might be amiss here?


Cheers,
Cristian
