Hello,

I am using mdadm 2.6.3 on Ubuntu 8.04.3 32 bits. Sometimes I hit this 
error when I try to create a RAID1:

mdadm --create --force --assume-clean /dev/md73 --level=1 
--bitmap=/root/bitmaps/md73bm.tmp --raid-devices=2 /dev/vg1/vol1 
--write-mostly /dev/sdj

Continue creating array? mdadm: failed to open bitmap file 
/root/bitmaps/md73bm.tmp: Text file busy

The bitmap file exists, but lsof doesn't show that it is in use by any 
other process.

If I copy the bitmap file and try the create again everything works fine.

Any idea what might be happening here?


Thanks,
