Re: [zfs-discuss] How to identify user-created zfs filesystems?
Thank you all for your help. It turns out that I just need to ignore the ones that have their mount points either not defined or are marked as legacy. It is good to learn about history command. Could come in handy. Regards, Peter -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] How to identify user-created zfs filesystems?
Folks, In my application, I need to present user-created filesystems. For my test, I created a zfs pool called mypool and two file systems called cifs1 and cifs2. However, when I run zfs list, I see a lot more entries: # zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 1.31M 1.95G33K /volumes/mypool mypool/cifs11.12M 1.95G 1.12M /volumes/mypool/cifs1 mypool/cifs2 44K 1.95G44K /volumes/mypool/cifs2 syspool 3.58G 4.23G 35.5K legacy syspool/dump 716M 4.23G 716M - syspool/rootfs-nmu-000 1.85G 4.23G 1.36G legacy syspool/rootfs-nmu-001 53.5K 4.23G 1.15G legacy syspool/swap1.03G 5.19G 71.4M - I just need to present cifs1 and cifs2 to the user. Is there a property on the filesystem that I can use to determine user-created filesystems? Thank you in advance for your help.

Re: [zfs-discuss] How to identify user-created zfs filesystems?
Hi Peter, I don't think we have any property that determines who created the file system. Would this work instead: # zfs list -r mypool NAME USED AVAIL REFER MOUNTPOINT mypool 172K 134G33K /mypool mypool/cifs131K 134G31K /mypool/cifs1 mypool/cifs231K 134G31K /mypool/cifs2 Or, take a look at user properties, which is text that you can apply to a file system for whatever purpose you choose.

Re: [zfs-discuss] How to identify user-created zfs filesystems?
You can use 'zpool history -l syspool' to show the username of the person who created the dataset. The history is in a ring buffer, so if too many pool operations have happened since the dataset was created, the information is lost.
