ZFS Question
We are looking into testing ZFS at our location. Because we are a government agency we have security and auditors breathing down our neck to make sure we are not opening any security holes.

My question is are there any ports or security concerns I would need to address if implemnting a ZFS file system? I can't believe there are any being that it's a file system but I don't know (or even pretend to know) everything in regards to solaris or unix.

Thanks
Robert

Get started reading the ZFS docs at docs.sun.com. I cannot speak to its security because I (we) won't use it due to its stability issues. If ZFS does use ports it probably uses them for RAID management similar to SVM. I yield, as always, to the wisdom of the documentation.

pay attention to backup and investigate if your current backup software can backup zfs filesystem and also will be able to restore. netbackup 6.x, dataprotector can't ....

Can you share your experience here ?

I have been using ZFS personally since it is available in Solaris Express (nov 2005) then later at work/on customer sites and so far has found it both extremely reliable and convenient.

About the OP question. ZFS doesn't open TCP ports but sharing a ZFS filesystem with NFS or CIFS will certainly do it.

Regarding security, an interesting feature which is worked on is ZFS on disk encryption. It is planned to be integrated in OpenSolaris by the end of the year: ZFS on disk encryption support at OpenSolaris.org
