We see Solaris, Illumos, BSD and more recently ZFS on Linux questions all give the same respect. I do hope we can get another, platform agnostic, home for this list. Despite having a lists.illumos.org DNS name, the Illumos ZFS list isn't just about Illumos. We have regular contributions from the FreeBSD and ZOL folks, they are on the list and we frequently use it to exchange contributions.

From: cindy swearingen [mailto:cindy.swearin...@gmail.com] This was new news to use too and we're just talking over some options yesterday afternoon so please give us a chance to regroup and provide some alternatives. This list will be shutdown but we can start a new one on java.net. Thanks Cindy - I, for one, am in favor of another list on java.net, because the development is basically split into oracle illumos. While illumos users might have a small aversion to using another oracle list, I think oracle users will likely have a much larger aversion to using a non-oracle list. So I think there's room for both lists, as well as just cause for both lists. If at all possible, I would advise preserving the history of these mailing lists. Extremely useful sometimes, when referencing past conversations and stuff, and searching for little tidbits via google. I would also advise making some sort of announcement on any of the other opensolaris mailing lists that happen to be active. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I am making the informed guess, that you're using it primarily on non-laptops, which have second hard drives, and you're giving the entire disk to the zpool. Right? Actually, my usage is with a laptop, but I've pretty much given up on doing anything serious in ZFS without going whole disk, so I hadn't run across the partitioning issues or the lack of ZFS.cache for mounting file based pools. Back to the day to day usage. I'm using it primarily with my MacBook Air and I have Seagate GoFlex thunderbolt adaptor into which I plug SSDs holding VMs and sources. While on the move, I leave the external drive in my bag and use a 1m thunderbolt cable so I'm tethered to the bag, but it's usable. Eventually, I'll probably get one of the StarTech 4 disk toaster docks on USB 3 for while I'm at the office, and continue to rely on the thunderbolt SSD while on the road. On the partitioning front, after thinking a bit, you should be able to tell Zevo to use a second partition on the main disk. The trick would be creating the partition normally as an HFS+ volume, unmounting it with something like sudo diskutil unmount disk0s4, followed by sudo zpool create zevo disk0s4 Oh, other side notes I almost forgot. To ensure that you don't chew up all of your memory with ARC it's also a good idea to disable spotlight searching on ZFS volumes (sudo mdutil -i off /Volumes/Zevo) Cheers, Erik ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You didn't say which OS version created the pool (ultimately - which pool version is there) and I'm not sure about support of the zfs versions in that flash you linked to. Possibly, OI LiveCD might do you a better job - but maybe your disks got too corrupted in some cataclysm :( However, generally, recent implementations should have several useful zpool import flags: * forcing an import with rollback to an older pool state (-F) - which may be or not be more intact (up to 32 or 128 transactions); * import without automount (-N) * read-only import (-o ro) which should panic in a lot less cases and allows to evacuate readable data by at least cp/rsync * import without cachefile and/or relocated pool root mountpoint (-R /a) so as to, in particular, not damage the namespace of your system by this pool (not really relevant in case of livecd's) Hopefully, you can either import without mounts and issue a zfs destroy of your offending dataset, or rollback (irreversible) to a working state. However, it is also possible that the corruption is among metadata. If you're lucky and just the latest transaction got broken during the crash (i.e. disk firmware ignored queuing and caching hints, and wrote something out of order), then rollback by one or a few TXGs may point you to an older root of metadata tree which is not yet overwritten by newer transactions (note: this is not guaranteed by the OS, just probable) and does contain consistent metadata in at least one copy of each of the metadata blocks. Breakage in /var/crash remotely suggests that your system tried to either create a dump (kernel panic) or more likely process one (via savecore in case of Solaris), and failed during this procedure in a mid-write. i try to get http://mfsbsd.vx.sk/ flash and load from it with zpool import http://puu.sh/2402E when i load zfs.ko and opensolaris.ko i see this message: Solaris: WARNING: Can't open objset for zroot/var/crash Solaris: WARNING: Can't open objset for zroot/var/crash zpool status: http://puu.sh/2405f resilvering freeze with: zpool status -v . zroot/usr:0x28ff zroot/usr:0x29ff zroot/usr:0x2aff zroot/var/crash:0x0 root@Flash:/root # how i can delete or drop it fs zroot/var/crash (1m-10m size i didn`t remember) and mount other zfs points with my data -- С уважением Куклин Константин.

Re: [zfs-discuss] zfs raid1 error resilvering and mount
Also, adding to my recent post: instead of resilvering, try to run zpool scrub first - it should verify all checksums and repair whatever it can via redundancy (for metadata - extra copies). Resilver is similar to scrub, but it has its other goals and implementation, and might be not so forgiving about pool errors. //Jim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

This is patently false. There's a reason why anytime someone has an issue the response from the Oracle team that posts here is almost always open a support ticket and give me the number. And then we never hear about it again/get the fix unless the end-user happens to come back and update us. If you think that Oracle is going to change that stance with a list hosted on Java.net, you're sadly mistaken. Their (collectively, I'm not speaking of any individual) only goal is to help paying customers. Period. The way they've decided to go about that is by hoarding knowledge. I've dealt with the company for over a decade, there will be no open discussions. NetApp has historically been open with their user community (although at times in recent history they have made the mistake of turtling up), which is why the toasters mailing list did as well as it did. Hell, Dave Hitz used to be a regular poster. MS forums are active and thriving because they've got a massive user base full of extremely experienced admins. If there was an open and free version of the MS products, I'm willing to bet that you'd find the closed source version a ghost town. For all the bashing MS has taken throughout history, they're a very open company relatively speaking. I can both browse their knowledge base and download hotfixes without any support contract. If you're going to have to open a support ticket to get help with issues anyways, why bother with a mailing list/forum? Just go straight to support. The reason THESE lists have done so well is because the guys who wrote the code actively participate and give detailed help in the open. If the only responses that ever came here were the Oracle responses to open up a ticket beyond anything but basic problems, this place would've died a long time ago. I think the saddest part of the whole situation is Oracle is so backwards and broken they don't even allow their employees to tell us what they aren't allowed to talk to us about.
