Linux – How set ZFS ACL permissions on CentOS 6

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

Well, whether you use traditional POSIX permissions or ACLs, you'll be using chmod on Solaris. I would suggest you use ACLs in this case. You'll have to apply the ACL separately to each file system in the tank storage pool. I suggest setting the aclmode and aclinherit properties of each filesystem to passthrough as well.

I think it's preferable to set the ACLs on the Solaris side of things instead of doing it through windows.

Basically it would look something like:

chmod -R A=\
group:suDevelopers:full_set,\
group:sysadmins:full_set,\
/tank/projects

chmod -R A=\
group:suDevelopers:full_set:allow,\
group:suStaff:full_set:allow,\
group:suContractors:full_set:allow
/tank/storage

chmod -R A=everyone@:full_set:allow /tank/sandbox

and etc as necessary. You can also use read_set for read-only permissions.

There's a lot of other ways you can cut things with ACLs, they're an extremely powerful system on Solaris. You can read man chmod and man zfs for details.

There's also this article which gives some further examples.

Also make sure you are using /usr/bin/chmod instead of /usr/gnu/bin/chmod which I believe is the default.
