Thanks, indeed it helped a lot. I also noticed that other zones have non-zero failure counters: UMA Slabs: 64, 0, 2666, 1051, 128676, 127 128 Bucket: 524, 0, 1455, 316, 82489, 97401821 g_bio: 132, 0, 0, 3190, 11471737, 3 ata_request: 192, 0, 0, 1880, 2905852, 378 rtentry: 124, 0, 2513, 1765, 802803, 132 pffrent: 16, 5075, 175, 3073, 48983719, 6 pffrag: 48, 0, 39, 3081, 15699916, 216 I'm quite anxious about "ata_request" failures.
