[zfs-discuss] To reserve space
Is there a way to reserve space for a particular user or group? Or perhaps to set a quota for a group which includes everyone else? I have one big pool, which holds users' home directories, and also the backend files for the svn repositories etc. I would like to ensure the svn server process will always have some empty space to work with, even if some users go hog wild and consume everything they can. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

zfs set reservation=100GB dataset/name That will reserve 100 GB of space for the dataset, and will make that space unavailable to the rest of the pool. That doesn't make any sense to me ... How does that allow subversionuser to use the space, and block joeuser from using it? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

How does that allow subversionuser to use the space, and block joeuser from using it? Oh - I get it - In the case of subversion server, it's pretty safe to assume all the svnuser files are under a specific subdirectory (or a manageably finite number of directories) and therefore could use a separate zfs filesystem within the same pool, and therefore that directory or directories could have a space reservation. I think that will be sufficient for our immediate needs. Thanks for the suggestion. Out of curiosity, the more general solution would be the ability to create a reservation on a per-user or per-group basis (just like you create quotas on a per-user or per-group basis). Is this possible? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Is this possible? OpenSolaris's zfs has supported quotas for a little while, so make sure you're using a recent build. I'm not sure if it's in Solaris 10, but I believe it is. Before quotas were supported, the answer was to create a new dataset per user, eg: tank/home/user1, tank/home/user2, etc. It's easy to do in zfs, but it doesn't always work for storage that is shared between users. -B -- Brandon High : bh...@freaks.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] To reserve space
The question is not how to create quotas for users. The question is how to create reservations for users. One way to create a reservation for a user is to create a quota for everyone else, but that's a little less manageable, so a reservation per-user would be cleaner and more desirable.

There is currently no way to do per-user reservations. That ZFS property is only available per-file system. Even per-user and per-group quotas are a recent addition (requested a lot from academic environments). For most of the existence of ZFS, only per-file system (i.e., data set) quotas were available. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
