Yup...it went away for a LONG time...maybe 30 seconds...
Does that mean there was that much unsynchronized data being held in memory
that wasn't being written out??
It DID fix the space allocation issue.
When I read the value before changing it, it said '0'.
when it finished, I tried to set it back to '0', but got an invalid argument.???
Was it really '2' or something else?
BTW -- it had been in the weird state for 13 hours before I issued the
order to drop_caches... seems like a long time not to cache data...?
