OK, some of the output scrolls too fast… since it can't load the filesystem it doesn't know to copy to serial console. But looking at the tail end, it's a lot of this: gpt_checkhdr: invalid entry size or number of entries gpt_checkhdr: invalid entry size or number of entries ptable_open: PMBR detected At least five sets of those, so I assume they are for at least disk2 - disk 7. Unfortunately I can't catch the output for disks 1 and 2, which are the only two bootable disks. :( Here's the bootparttest output: $ sudo ./bootparttest da0 GEOM provider "da0" opened Mediasize: 32296140800 Bytes (63078400 sectors) Sectorsize: 512 Bytes da0: read 1 blocks from the offset 0 [+0] da0: read 1 blocks from the offset 1 [+0] ptable_open: PMBR detected da0: read 1 blocks from the offset 1 [+0] da0: read 32 blocks from the offset 2 [+0] da0: read 1 blocks from the offset 63078399 [+0] ptable_gptread: new GPT partition added ptable_gptread: new GPT partition added ptable_gptread: new GPT partition added Partition table detected: GPT da0p1: FreeBSD boot 64k da0p2: FreeBSD swap 2048M da0p3: FreeBSD ZFS 28G GEOM provider "da1" opened Mediasize: 32000000000 Bytes (62500000 sectors) Sectorsize: 512 Bytes da1: read 1 blocks from the offset 0 [+0] da1: read 1 blocks from the offset 1 [+0] ptable_open: PMBR detected da1: read 1 blocks from the offset 1 [+0] da1: read 32 blocks from the offset 2 [+0] da1: read 1 blocks from the offset 62499999 [+0] ptable_gptread: new GPT partition added ptable_gptread: new GPT partition added ptable_gptread: new GPT partition added Partition table detected: GPT da1p1: FreeBSD boot 64k da1p2: FreeBSD swap 2048M da1p3: FreeBSD ZFS 27G $ sudo ./bootparttest da2 GEOM provider "da2" opened Mediasize: 1000204886016 Bytes (1953525168 sectors) Sectorsize: 512 Bytes da2: read 1 blocks from the offset 0 [+0] da2: read 1 blocks from the offset 1 [+0] ptable_open: PMBR detected da2: read 1 blocks from the offset 1 [+0] gpt_checkhdr: invalid entry size or number of entries da2: read 1 blocks from the offset 1953525167 [+0] gpt_checkhdr: invalid entry size or number of entries Partition table detected: None (Output for da3 - da7 are identical to da2.) So I'm guessing something doesn't like the metadata on the data drives. This is a raidz2, so I can certainly offline the disks one by one to rebuild the partition tables, though that'll take ages; the I/O performance of this system is awful. But I do wonder why the zfsloader from 8.4 can handle whatever's going on in there and 9.2 can't. Thanks!
