Subject: Unmounting a busy RO-Filesystem
Date: Tue, 17 Dec 2002 06:36:35 +0530 [thread overview]
Message-ID: <3DFE789B.9020507@ToughGuy.net> (raw)
I have 3 partitions. /dev/hda3 for '/' , /dev/hda1 for /boot and
/dev/hda2 for swap.
I boot & then i do a CTRL+ALT+SYSRQ+U. '/' and '/boot' are now
remounted ReadOnly.
1) cd '/boot'
2) umount /boot ----> This gives me an error "Device Busy"
3) cd /
4) umount / -------> No error
5) echo $? -----> outputs '0' indicating success. !!!!!!!!
When i do the above by skipping the Sysrq part, i get the usual expected
errors.
So is the above behaviour expected ? I tried this on 2.4.19 & 2.5.51.
Same results.
I am subscribed to the list
TIA
Bourne
