| # DESCRIPTION: |
| # Persistent L2ARC with an encrypted ZFS file system succeeds |
| # |
| # STRATEGY: |
| # 1. Create pool with a cache device. |
| # 2. Create a an encrypted ZFS file system. |
| # 3. Create a random file in the encrypted file system and random |
| # read for 10 sec. |
| # 4. Export pool. |
| # 5. Read the amount of log blocks written from the header of the |
| # L2ARC device. |
| # 5. Import pool. |
| # 6. Mount the encrypted ZFS file system. |
| # 7. Read the amount of log blocks rebuilt in arcstats and compare to |
| # (5). |
| # 8. Check if the labels of the L2ARC device are intact. |
| # |
| # * We can predict the minimum bytes of L2ARC restored if we subtract |
| # from the effective size of the cache device the bytes l2arc_evict() |
| # evicts: |
| # l2: L2ARC device size - VDEV_LABEL_START_SIZE - l2ad_dev_hdr_asize |
| # wr_sz: l2arc_write_max + l2arc_write_boost (worst case) |
| # blk_overhead: wr_sz / SPA_MINBLOCKSIZE / (l2 / SPA_MAXBLOCKSIZE) * |
| # sizeof (l2arc_log_blk_phys_t) |
| # min restored size: l2 - (wr_sz + blk_overhead) |
