Fun with Filesystems

I think there's a race condition in Solaris... we had a filesystem get full with Oracle archivelogs, so I removed them, then checked to see what effect that had:

# rm D*_60[012345]?_*.dbf
# df -h .
Filesystem             size   used  avail capacity  Mounted on
/oracle/D01/saparch    5.9G 16384E   6.4G 301049486643838% /oracle/D01/saparch

A moment later, it was happy:

# df -h .
Filesystem             size   used  avail capacity  Mounted on
/oracle/D01/saparch    5.9G   257M   5.6G     5%    /oracle/D01/saparch

This is not the first time I've noticed some wierdness with removing data on S10. Last time, I wiped out a copy of our big oracle database, (rm -rf sapdata*/*) which only took a few seconds, but to unmount the filesystem took over 8 hours.
