[PR] fix: Failed to remove unwritable directories when creating tsfile [iotdb]

["761417898 (via GitHub)" <gi...@apache.org>]

761417898 opened a new pull request, #16122:
URL: https://github.com/apache/iotdb/pull/16122

   The issue occurs because mkdirs() fails silently - it returns false rather than throwing an IOException when unable to create directories.
   ```
   try {
         return folderManager.getNextWithRetry(
             baseDir -> {
               String tsFileDir =
                   baseDir
                       + File.separator
                       + logicalStorageGroup
                       + File.separator
                       + virtualStorageGroup
                       + File.separator
                       + timePartitionId;
               fsFactory.getFile(tsFileDir).mkdirs();
               return tsFileDir
                   + File.separator
                   + generateNewTsFileName(
                       time,
                       version,
                       innerSpaceCompactionCount,
                       crossSpaceCompactionCount,
                       customSuffix);
             });
       } catch (DiskSpaceInsufficientException e) {
         LOGGER.error("All disks are full, cannot create tsfile directory", e);
         throw new IOException("Disk space insufficient", e);
       } catch (Exception e) {
         LOGGER.warn("Failed to create tsfile directory after retries", e);
         throw new IOException("Failed to create directory after retries", e);
       }
   ```
