Bulk upload on mounted disk : operation not support

Support Bug
1

Dear all,

Bulk upload on mounted disk seems not working with large input files
on Stardog Version 7.8.3 / Mac OS X 11.2, Java 16.0.1

stardog-admin db create -n watdiv2 /Volumes/Samsung_T5/watdiv-skew-10M.ttl
Exception during index bulk loading for watdiv2

in the the log (operation not supported):

WARN 2022-02-19 16:03:31,930 [Stardog.Executor-21] com.complexible.stardog.index.disk.rocks.RocksIndexUpdateRunner:run(151): Error updating index

java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.io.IOException: IO error: while link file to /Volumes/Samsung_T5/stardog/data/\

000070.sst: /Volumes/Samsung_T5/stardog/tmp_sst_data/t__index_sst_file_82396815783552_0_99.sst: Operation not supported`

As you see, the data are written on a SSD mounted disk.

The same bulk upload on the native disk on the mac works:

stardog-admin db create -n watdiv2 /Volumes/Samsung_T5/watdiv-skew-10M.ttl
Bulk loading data to new database watdiv2.
Loaded 9?481?161 triples to watdiv2 from 1 file(s) in 00:01:40.479 @ 94,4K triples/sec.
Successfully created database 'watdiv2'.

What's going wrong on mounted disks ??

As per System Requirements | Stardog Documentation Latest, Java 16 is not supported.

Does the error occur with Java 8 or 11?

Dear Serge,
