[zfs-discuss] hierarchical share of zfs filesystem
I have a quick question about ZFS filesystems and snapshots and NFS shares. Is it possible to have one mount point for a set of ZFS filesystems? Lets say I have /export/homes as a ZFS filesystem and NFS shared, I create a new ZFS filesystem /export/homes/user1 I need to explicitly mount it. Only the mount point is visible under /export/homes. This has been standard NFS with devices mounted, ie. submounts are not exported, but that becomes very unhandy with dynamic ZFS and snapshots under NFS? Again, the question is if I can export all ZFS filesystems under a specific mount point. -- Jan Hendrik Mangold Sun Microsystems Senior Lead Staff Engineer 650-585-5484 (x81371) http://learning.central/wiki/display/~13922 idle hands are the developers workshop ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Now zpool import comes up empty. Have I lost all my data on that ZFS? Howcan I check? Sorry if I'm stating something too basic here -- no insult intendedno problem :)It sounds like the on-disk Solaris isn't aware of the new drives. Did youdo a reconfigure-boot after adding them? Do they show up as "configured"in a "cfgadm -al" list?I can see and access the disks with prtvtoc. cfgadm returnscfgadm: Configuration administration not supported --Jan Hendrik Mangold Sun Microsystems650-585-5484 (x81371)"idle hands are the developers workshop" ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] how do I find out if I am on a zfs filesystem
This may be a dumb question, but is there a way to find out if an arbitrary filesystem is actually a zfs filesystem? Like if I were to write a script that needs to do different steps based on the underlying filesystem.Any pointers welcome. --Jan Hendrik Mangold Sun Microsystems650-585-5484 (x81371)"idle hands are the developers workshop" ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Re: Re: zfs clones
Hey Mattwere you able to reproduce this? I am using the straight S10U2 bits. I can give you access to the system, if you want. One last piece of information should be that my pools are created of files, due to lack of disks for experimenting.On Sep 18, 2006, at 10:04 PM, Matthew Ahrens wrote:Jan Hendrik Mangold wrote: I didn't ask the original question, but I have a scenario where Iwant to use clone as well and encounter a (designed?) behaviour I amtrying to understand.I create a filesystem A with ZFS and modify it to a point where Icreate a snapshot [EMAIL PROTECTED] Then I clone that snapshot to create a newfilesystem B.

Or is this something not possible with ZFS? Hmm, actually this is unexpected; you shouldn't have to unmount the clone to do the rollback on the origin filesystem. I think that our command-line tool is simply being a bit overzealous. I've filed bug 6472202 to track this issue; it should be pretty straightforward to fix.Thanks for bringing this to our attention!--matt --Jan Hendrik Mangold Sun Microsystems650-585-5484 (x81371)"idle hands are the developers workshop" ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Re: Re: zfs clones
The initial idea was to make a dataset/snapshot and clone (fast) and then separate the clone from its snapshot. The clone could be then used as a new independant dataset. The send/receive subcommands are probably the only way to duplicate a dataset. I'm still not sure I understand what about clones makes you not want to use them. What do you mean by separate the clone from its snapshot? Is it that you want to destroy the filesystem that the clone was created from? To do that you can use 'zfs promote'. Is it that you want to guarantee space availability to overwrite it? To do that you can use 'zfs set reservation'. --matt I didn't ask the original question, but I have a scenario where I want to use clone as well and encounter a (designed?) behaviour I am trying to understand.
