Re: [zfs-discuss] zfs dynamic lun expansion
If you are using the whole lun as your vdev in zpool and using EFI label, you can export zpool, relabel the luns (using the new capacity) and import that zpool. You should be able to see the increased size then. FYI, dynamic lun expansion feature is under testing and will be available soon.

Re: [zfs-discuss] ZFS, iSCSI + Mac OS X Tiger (globalSAN iSCSI)
Hey there - This is very likely completely unrelated, but here goes anyhoo... I have noticed with some particular ethernet adapters (e1000g in my case) and large MTU sizes (8K) that things (most anything that really pushes the interface) sometimes stop for no good reason on my x86 Solaris boxes. After it stops, I'm able to re-connect after a short time and it works for a while again... (Really must get around to properly reproducing the problem and logging a bug too...) I'd be curious to know if setting the MTU to 1500 on both systems makes any difference at all. Note that I have only observed this with my super cheap adapters at home. I'm yet to see if (though also yet to try really hard) on the more expensive ones at work... Again - Likely nothing to do with your problem, but hey. It has made a difference for me before... Cheers.

[zfs-discuss] zfs dynamic lun expansion
Hi, I had 2 luns in a zfs mirrored config. I increased the size of both the luns by x gig and offlined/online the individual luns in the zpool, also tried an export/import of the zpool, but i am unable to see the increased sizewhat would i need to do to see the increased size?...or is it not possible yet?

[zfs-discuss] Re: ZFS and Firewire/USB enclosures
Besides the one you mention, bug 6560174 also shows the problems I've seen with ZFS on firewire. (This bug also shows the blank status page.) Is there any way to know if these will be addressed?

Re: [zfs-discuss] data structures in ZFS

Well it's a nice picture, thanks! (could you also make a .svg version available?) As a zfs-code-illiterate interested bystander, it would be nice if the various objects were annotated with short descriptions of their intent. The same goes for the pointers to objects in other layers, what is the pointer keeping track of, what kind of information passes between the layers. I'd also love to see what happens on the block level when you take a snapshot. What objects end up pointing to the same things etc. And if you could make it into a 3d zooming movie with change-by-change animations that'd be awesome! ;-) But this is certainly a lot easier to grok than the linear descriptions in the on-disk format guide.

[zfs-discuss] ZFS, iSCSI + Mac OS X Tiger (globalSAN iSCSI)
I have set up an iSCSI ZFS target that seems to connect properly from the Microsoft Windows initiator in that I can see the volume in MMC Disk Management. When I shift over to Mac OS X Tiger with globalSAN iSCSI, I am able to set up the Targets with the target name shown by `iscsitadm list target` and when I actually connect or "Log On" I see that one connection exists on the Solaris server. I then go on to the Sessions tab in globalSAN and I see the session details and it appears that data is being transferred via the PDUs Sent, PDUs Received, Bytes, etc. HOWEVER the connection then appears to terminate on the Solaris side if I check it a few minutes later it shows no connections, but the Mac OS X initiator still shows connected although no more traffic appears to be flowing in the Session Statistics dialog area. Additionally, when I then disconnect the Mac OS X initiator it seems to drop fine on the Mac OS X side, even though the Solaris side has shown it gone for a while, however when I reconnect or Log On again, it seems to spin infinitely on the "Target Connect..." dialog. Solaris is, interestingly, showing 1 connection while this apparent issue (spinning beachball of death) is going on with globalSAN. Even killing the Mac OS X process doesn't seem to get me full control again as I have to restart the system to kill all processes (unless I can hunt them down and `kill -9` them which I've not successfully done thus far). Has anyone dealt with this before and perhaps be able to assist or at least throw some further information towards me to troubleshoot this?

Each pool has its own name. Then, later, you refer to each pool (and filesystem) using its name. Regards przemol -- http://przemol.blogspot.com/ -- O Twoich stronach juz się mówi...
