That is your problem right there. Solaris doesn't recognise this partition type. FreeBSD I think does. I'm not sure what you can do to get Solaris to recognise this.

ZFS should just find this as /dev/dsk/c?t?d?p1 if the structures really are unrecognizable as a zpool device (on x86 only - won't work on sparc). I haven't tried importing in this way, but I'm pretty sure I have created zpools on raw primary fdisk partitions.

There was a post from Ricardo on zfs-fuse list some time ago. Apparently if you do a zpool create on whole disks, Linux on Solaris behaves differently: - solaris will create EFI partition on that disk, and use the partition as vdev - Linux will use the whole disk without any partition, just like with a file-based vdev. The result is that you might be unable to import the pool on *solaris or *BSD. The recommended way to create a portable pool is to create the pool on a partition setup recognizable on all those OS. He suggested a simple DOS/MBR partition table. So in short, if you had created the pool on top of sda1 instead of sda, it will work. I'm surprised though that you can offlined sda and replaced it with sda1 when previously you said I see that if I try to replace sda with sda1, zpool complains that sda1 is too small -- Fajar ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

But I found that a standard PC/Linux partition reserves around 24MB at the beginning of the disk, and an EFI (or actually, GPT) disklabel and partition only uses a few 100KB.

I'm still confused as to why Solaris won't recognise them, but both Solaris and FreeBSD will happily import/export pools created on an EFI/GPT partition using FreeBSD's gpart(1), so if Linux understands GPT partitions as well that's probably the way to go for portable pools. FreeBSD 7.2-STABLE will NOT see pools created by OpenSolaris though, again I don't understand why this is since it should in theory understand EFI partition tables fine. I'll try importing a pool on a USB disk with a GPT table on my mac and see what happens. -- Alasdair Muckart | William de Wyke | http://wherearetheelves.blogspot.com Any sufficiently advanced stupididty is indistinguishable from malice -- James D.
