And, after 19 days the problem has shown up again: Oct 7 17:34:24 olympic kernel: [1657429.788105] EXT4-fs (dm-2): pa ffff880004211a50: logic 512, phys. 10298368, len 512 Oct 7 17:34:24 olympic kernel: [1657429.790412] EXT4-fs error (device dm-2): ext4_mb_release_inode_pa:3773: group 314, free 497, pa_free 495 Oct 7 17:34:24 olympic kernel: [1657429.793168] Aborting journal on device dm-2-8.
