Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?

Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?
It's not intuitive because when you know that -o sets options, an error message saying that it's not a valid property makes you think that it's not possible to do what you're trying. Documented and intuitive are very different things. I do appreciate that the details are there in the manuals, but for items like this where it's very easy to pick the wrong one, it helps if the commands can work with you. The difference between -o and -O is pretty subtle, I just think that extra sentence in the error message could save a lot of frustration when people get mixed up.

Well, I hadn't previously thought about the fact that the zpool create command creates both a pool *and a filesystem*. So the fact that casesensitivity is a filesystem property meant to me that it couldn't be used on the zpool command. I wouldn't have been looking at the man page to find the -O switch, because it's obvious from the structure that it won't be there -- zpool manipulates pools, zfs manipulates filesystems. So I'm not completely sure non-intuitive is how I'd describe it; but it's off in a weird corner I hadn't even noticed existed.

Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?
Yeah, I knew that zpool creates a root filesystem (since it's listed in zfs list), but I also knew these properties had to be set on creation, not after, so I figured zpool -o was the way to do it. Completely threw me when zpool -o said it wasn't a valid property, I'd never have thought to look for a different command to -o. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?
If you have an older Solaris release using ZFS and Samba, and you upgrade to a version with CIFS support, how do you ensure the file systems/pools have casesensitivity mixed? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?
You can check whether it's set with: $ zfs get casesensitivity pool/filesystem If you're using CIFS, you need that to return mixed or insensitive. If it returns sensitive, it will cause you problems. Unfortunately there's no way to change this setting on an existing filesystem, so if you do have the wrong setting you'll need to create a new filesystem and move your files over. If you have enough disk space it's relatively easy to do with CIFS: - Create a new filesystem on the server using zfs create -o casesensivity=mixed - Share it under a new name: zfs set sharesmb=name= pool/filesystem - Move all the files (I did a cut/paste with windows explorer since this preserves permissions, robocopy would probably work too, mv in solaris might but I've not tried that) - Delete the original filesystem and change the name the new one is shared under with zfs set sharesmb=name= - Rename the new filesystem if needed with zfs rename -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Any way to set casesensitivity=mixed on the main pool?
Well for one, occasional 'file not found' errors when programs (or shortcuts) check whether a file exists if the case is wrong. And you can expect more problems too. Windows systems are case insensitive, so there's nothing stopping a program referring to one of it's files as file, File and FILE. They'll all refer to the same thing. Under a case sensitive system however, those are three separate files, and there's no way to know what kinds of problems that could cause. Suffice to say that while you might get away with running ZFS and CIFS in case sensitive mode for a bit, sooner or later it's going to go horribly wrong. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
