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.

I want to create an FS with a much smaller limit. how?

I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)

With Solaris 11 coming out with a requirement of ZFS on the root disk, I was curious to know who is using the Zeta File System now?
I have been using ZFS for the past year and don't plan to go back to UFS since ZFS is much more reliable and easier to maintain. (13 Replies)

I'm having trouble increasing my reservations on some ZFS filesystems, although there seems to be enough space in the zpool, and no constraints on the parent device.

deallocate
deallocate(1) deallocate(1)
NAME
deallocate - device deallocation
SYNOPSIS
deallocate [-s] device
deallocate [-s] [-F] device
deallocate [-s] -I
The deallocate utility deallocates a device allocated to the evoking user. device can be a device defined in device_allocate(4) or one of
the device special files associated with the device. It resets the ownership and the permission on all device special files associated with
device, disabling the user's access to that device. This option can be used by an authorized user to remove access to the device by another
user. The required authorization is solaris.device.allocate.
When deallocation or forced deallocation is performed, the appropriate device cleaning program is executed, based on the contents of
device_allocate(4). These cleaning programs are normally stored in /etc/security/lib.
The following options are supported:
device Deallocate the device associated with the device special file specified by device.
-s Silent. Suppresses any diagnostic output.
-F device Forces deallocation of the device associated with the file specified by device. Only a user with the solaris.device.revoke
authorization is permitted to use this option.
-I Forces deallocation of all allocatable devices. Only a user with the solaris.device.revoke authorization is permitted to
use this option. This option should only be used at system initialization.
The following exit values are returned:
non--zero An error occurred.
/etc/security/device_allocate
/etc/security/device_maps
/etc/security/dev/*
/etc/security/lib/*
