Description
java/nio/file/FileSystem/Basic.java may fail at looping the FileStore:

        // santity check method - need to re-visit this in future as I/O errors
        // are possible
        for (FileStore store: fs.getFileStores()) {
            System.out.println(store);
        }

Especially when NFS mounts has temporary issues.

The similar issue also reported against java/nio/file/FileStore/Basic.java in JDK-8058789
Comments
With the fix for JDK-8173910 in place, the test should not likely continue to fail due to attempting to access stale NFS mounts. If the test no longer fails after a significant number of runs, please add a comment to that effect to this issue. Thanks.

We've attempted in the past to use "df" and other tools to sanity check the environment but these tools also hang.
