Jason Huynh created GEODE-8282:
----------------------------------
Summary: Creating diskstore with size appened to name doesn't seem
to work as documented
Key: GEODE-8282
URL: https://issues.apache.org/jira/browse/GEODE-8282
Project: Geode
Issue Type: New Feature
Reporter: Jason Huynh
The create diskstore --dir option is documented with:
...Optionally, directory names may be followed by {{#}} and the maximum number
of megabytes that the disk store can use in the directory. For example:
{code:java}
--dir=/data/ds1
--dir=/data/ds2#5000
{code}
When creating a disk store through gfsh with the size appended, it does not
appear to limit the size of the directory. There also doesn't seem to be much
validation...
for example, when using a negative value we can see that the size described
does not match what we expected to be our limit.
{code:java}

It also appears in code to only affect calculation of disk usage etc, but I
didn't dig very deep. If it is used there, the negative value will probably
mess with that calculation.
