Re: [zfs-discuss] Moving a pool from FreeBSD 8.0 to opensolaris
I don't know how much progress has been made on this, but back when I moved from FreeBSD (an older version, maybe the first to have stable ZFS) to Solaris, this couldn't be done since they were not quite compatible yet. I got some new drives since the ones I had were dated, copied the data to the new Solaris system with a network connection, and then tried to import the old drives to see if it could be done. If I remember correctly (which I might not), they imported, but the data wasn't there. I know it didn't work. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Moving a pool from FreeBSD 8.0 to opensolaris
This isn't an option for me. The current machine is going to be totally upgraded, New motherboard, new ram (ecc) new controller cards and 9 new hard drives. Current pool is 3 raidz1 vdevs with 4 drives each (all 1 tb) It's about 65% full. If i have to use some other filesystem that is an option, but i need to be able to use the 9 new disks to somehow backup the data on the FreeBSD 8.0 system, then destory the old pool, create a new pool using the same drives in Opensolaris with the new motherboard/controillers/memory and copy the data to the new pool Afterward i intend to create more vdevs (i haven't decided which way to go yeti could either do 5 4 disk raidz vdevs, 4 5 disk raidz vdevs or maybe something weird like 2 7 disk raidz vdevs with 1 6 disk raidz vdevi don't know yetbut that's beside the point) On Sun, Dec 27, 2009 at 2:07 PM, Austin shyguy91...@atwelm.com wrote: I don't know how much progress has been made on this, but back when I moved from FreeBSD (an older version, maybe the first to have stable ZFS) to Solaris, this couldn't be done since they were not quite compatible yet.

My Commodore 128D could boot CP/M but couldn't understand FAT32 - that doesn't mean that therefore FAT32 isn't OS independent either. PC partition table is also not OS specific and is OS independent. Most partition tables are OS independent, they ar often specified by how you boot the platform. On a PC EFI is very OS specific as most OS on that platform does not support EFI. EFI is platform independent for solaris. Solaris on sparc and solaris on PC uses different partition tables unless you use EFI as EFI is supported by Solaris on sparc and x86. This is manly a Solaris problem as there is no reason for Solaris on sparc to not read a pc partition table. The reason that EFI is used by default for zfs is that it is platform independent (and that it can handle bigger disks on sparc). Unless you have to boot from it, then it is very platform dependent... But the point was that ZFS on solaris have to have a partition table, so you must make a partition table on FreeBSD that solaris can read. It does not mater if the format is OS specific or not. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

There is nothing OS specific about EFI, regardless of whether any given OS supports EFI or not. Nor does it need to be a PC - I have several Mac PPCs that can read EFI partitioned disks (as well as some Intel ones). These can also be read by other systems that understand EFI partitioned disks.

What you mean by most OS on PC does not support EFI and what is PC platform anyway? There is some crappy i386 hardware that does not supports EFI booting — this part is true, but so what? — e.g. ACPI is also often screwed (remembering 0.5 year ago shouting on a Slashdot how one dude was trying to boot FreeBSD and it rendered that hardware was designed only for Windows and remembering that OpenSolaris pretends to be Windows in this case). EFI is a label, that differs from the VTOC mainly by supporting larger than 2GB disks (exceptions are SCSI and SSD drives), no information about cylinders, head or sectors is stored there and it is supported on x86 as well. The label is created by default when you format your drive in Solaris, using entire disk. Label is not any OS dependent. The only thing that if it comes to Linux, you have to enable GPT/EFI support in the kernel, because in x86 and amd64 kernels usually it is disabled by default. As of FreeBSD I have no idea about the status (because it is chronical challenge to FreeBSD community when nobody has any idea when things is gonna be done/released there anyway), but you might contact Rui Paulo (rpaulo@) on this topic. Although I don't know how things are moving forward in order to support ZFS on Windows. :-) Take care. -- Kind regards, BM Things, that are stupid at the beginning, rarely ends up wisely. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Moving a pool from FreeBSD 8.0 to opensolaris
guys! it's alll good. We don't need to argue about whether or not EFI is or isn't platform independentwhat would be nice, is if someone can explain the best way to create a zpool in freebsd that i can import into solaris so i can move my data. I've still got a week or two before i have to do this, so any info is likely to be helpful.

Re: [zfs-discuss] Moving a pool from FreeBSD 8.0 to opensolaris
On Thu 24/12/09 10:31 , Thomas Burgess wonsl...@gmail.com sent: I was wondering what the best method of moving a pool from FreeBSD 8.0 to OpenSolaris is. When i originally built my system, it was using hardware which wouldn't work in opensolairs, but i'm about to do an upgrade so i should be able to use Opensolaris when i'm done. I know i probably can't import my current pool into opensolaris, but i was thinking i could use the 8 drives and create a pool which i COULD import, using that to back up my data. Is the pool on slices or whole drives? If the latter, you should be able to import the pool (unless BSD introduces any incompatibilities). I'm not sure how to go about it. Basically, how should i format my drives in FreeBSD, create a ZPOOL which can be imported into OpenSolaris. I'm not sure about BSD, but Solaris ZFS works with whole devices. So there isn't any OS specific formatting involved. I assume BSD does the same. Also, is it possible to install opensolaris to compact flash cards? The reason i ask is that i know the root pool can't be raidz. Yes, I had a system booting of CD cards (in an IDE/CF adapter). -- Ian. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

If the latter, you should be able to import the pool (unless BSD introduces any incompatibilities). It's on whole disks but if i remember right those disks are tied to the highpoint raid card. I didn't know about passthrough at the time. This is why i'm asking about making a NEW pool. I figure i can make a new pool connected as passthrough devices. What i don't know is how i should partition the drives, or if i should at all. FreeBSD has it's own type of partitions, then it has internal slices. On the current pool, the drives showed up as /dev/da0 /dev/da1 /dev/da2, so on and so forth. The only thing i did was use glabel to make sure the zpool always used the same drive incase the letters changed. so my current pool is actually created using the glabel names and not the /dev/da0 /dev/da1 devices, but i'm fairly sure it's about the same. What i'm thinking is, if i add the drives to the current 8 slots i have free (i have 4 sata ports on the current motherboard and 4 more left on the raid card) and set the 4 on the raidcard as passthrough devices, then create a new zpool and copy the important stuff over, then i should be able to import that into opensolaris. What i DONT know iswill opensolaris recognized the drivesdo i need to use some sort of partioning scheme (Geom, GPT, whatever) or should i just try to use raw drives. I do not want to lose my datai figured this is the best place to ask. I'm not sure about BSD, but Solaris ZFS works with whole devices. So there isn't any OS specific formatting involved.
