I want to move my pool (consisting of five 1.5TB sata drives in raidz1) to a different computer. I am encountering issues with controllers - the motherboard (Asus P5BV-C/4L) has 8 sata ports: 4 on a marvell 88se6145, which seems not to be supported at all; and 4 on intel 82801G, which uses the pci-ide driver. I added a 4-port pci sata card, a Silicon Image 3114, which appeared to work after updating its bios to identify itself as ide. it also uses the pci-ide driver.
however, attempting to import the pool, it complains of corrupted data and fails to import. moving the pool back to the previous computer (where they are all on a Intel 82801JI SATA AHCI Controller, using ahci driver), the pool is in fact just fine. the size of the drives is 1500301910016 bytes. but, under both of the pci-ide controllers, the size is appearing to be 1500295200768 bytes - 6,709,248 less. why would it be misreporting by over 6MB? Is there a way to fix this? it doesn't seem to be the fault of either controller; I booted into linux and it sees the drives as the correct size. (as an aside, I am not sure how to properly get the size of the disk in opensolaris, so I did that by reading from the disk's p0 device with dd until I hit EOF. if anybody can tell me how to more easily get the size in bytes, I'd appreciate that.) -Ethan
