Hello !

I'm experiencing a data imbalance issue with one of my nodes within a
3-nodes C* 2.1.4 cluster. All of them are using JBOD (2 physical disks),
and this particular node seems to have recently made a relatively big
compaction (I'm using STCS), creating a 56Go SSTable file, which results in
one of the disks being 94% used and the other only 34%. I've looked around
for similar issues, and this was supposed to be fixed in 2.1.3 (
CASSANDRA-7386 <https://issues.apache.org/jira/browse/CASSANDRA-7386>). DSE
docs
<https://support.datastax.com/hc/en-us/articles/204226239-DSE-can-run-out-of-disk-space-using-JBOD-even-with-disks-available->
suggest
stopping the node and moving some SSTables around between the disks to
force a better balance, while trying to make as few moves as possible. Can
I just stop the node, move the 56Go SSTable (so I guess the Summary, TOC,
Digest, Statistics, CompressionInfo, Data, Index and Filter files) and
restart the node?

Thanks a lot for your help,
Best,

Axel
