When you rename a directory, it should check for it being a mountpoint and warn appropriately. (adding ZFS specific code to DTRT is perhaps asking for a bit too much.) evidently it got an error for the rename(2) and instead started to copy/delete the original. *inside* some filesystems, this is probably correct behaviour, but when the object is a filesystem, I don't think anyone want this behaviour. if they want to move data off the filesystem, they should go inside, mark all files, and drag (or ^X ^V) the files wherever they should go. So, I removed cloud/movies with zfs destroy --- BIGGER MISTAKE I see the reasoning behind this, but as you've learnt the hard way: always double-check before using zfs destroy. -- Kjetil T.

Yes, I am glad that I learned this lesson now, rather than in 6 months when I have re-purposed the exiting drives...makes me all the more committed to maintaining an up to date remote backup. The reality is that I can not afford to mirror the 8TB in the zpool, so I'll balance the risk and just backup the important items like music, document and photo's. ISO's and DVD's I can always recreate. Thanks guys for the support. I'll do alot more reading on ZFS/datasets etc. befor I mess with the server again!...hmmm, actually, I just had a thought, I will also create a playpool when I can try out things before using them on the main pool. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

In that regard, you can use a file based zpool, no need to slice your disks that way.

Re: [zfs-discuss] Oops, ran zfs destroy after renaming a folder and deleted my file system.
well, both I guess... I thought the dataset name was based upon the file system...so I was assuming that if i renamed the zfs filesystem (with zfs rename) it would also rename the dataset... ie... #zfs create tank/fred gives... NAMEUSED AVAIL REFER MOUNTPOINT tank/fred 26.0K 4.81G 10.0K /tank/fred and then #zfs rename tank/fred tank/mary will give... NAMEUSED AVAIL REFER MOUNTPOINT tank/mary 26.0K 4.81G 10.0K /tank/mary It's all rather confusing to a newbit like me I must admit...so please post examples so I can understand it. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
