And now the pool failed :( I'm very puzzled by the fact, that the 'checksum mismatch' errors seem to occur at the same offset on multiple disks: Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da0 offset=58350080 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da1 offset=58350080 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da2 offset=58350080 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da3 offset=58350080 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da2 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da3 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da4 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da5 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da6 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da7 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da8 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da9 offset=38010880 size=512 Aug 20 01:00:24 leibniz root: ZFS: checksum mismatch, zpool=pil path=/dev/da10 offset=38010880 size=512 Can anybody offer anything to help me with this? I'm pretty much at a loss as to how I can find the cause of this. -- Kenneth Schmidt pil.dk
