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... (3 Replies)
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)
I have a oracle instance running in NGZ which is on zfs dataset. Is there any possibility if i can take a zfs snapshot without shutting down the zone and then restore the zfs on other server and start oracle .. will the data be fine or not ? (2 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)
Hi,
I need some advice please. I have this server with a couple of zpools, lets call them

What I am trying to do is reuse space that was used from an old solaris zone and take that space used in the 2 disk mirror from the 2nd zpool and relocate it to /var/audit in the root pool. The pysical server has 4 disks. 2 disks are a mirrored root zone(c1t0d0s0,c1t1d0s0) and the other were the... (1 Reply)
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.
Note that I'm using refreservation instead of reservation, so I'm not constrained by the reservation on the parent device (or... (1 Reply)

acl_check
acl_check(3SEC) File Access Control Library Functions acl_check(3SEC)NAME
acl_check - check the validity of an ACL
SYNOPSIS
cc [ flag... ] file... -lsec [ library... ]
#include <sys/acl.h>
int acl_check(acl_t *aclp, int isdir);
DESCRIPTION
The acl_check() function checks the validity of an ACL pointed to by aclp. The isdir argument checks the validity of an ACL that will be
applied to a directory. The ACL can be either a POSIX draft ACL as supported by UFS or NFSv4 ACL as supported by ZFS or NFSV4.
When the function verifies a POSIX draft ACL, the rules followed are described in aclcheck(3SEC). For NFSv4 ACL, the ACL is verified
against the following rules:
o The inheritance flags are valid.
o The ACL must have at least one ACL entry and no more than {MAX_ACL_ENTRIES}.
o The permission field contains only supported permissions.
o The entry type is valid.
o The flag fields contain only valid flags as supported by NFSv4/ZFS.
If any of the above rules are violated, the function fails with errno set to EINVAL.
RETURN VALUES
If the ACL is valid, acl_check() returns 0. Otherwise errno is set to EINVAL and the return value is set to one of the following:
EACL_INHERIT_ERROR There are invalid inheritance flags specified.
EACL_FLAGS_ERROR There are invalid flags specified on the ACL that don't map to supported flags in NFSV4/ZFS ACL model.
EACL_ENTRY_ERROR The ACL contains an unknown value in the type field.
EACL_MEM_ERROR The system cannot allocate any memory.
EACL_INHERIT_NOTDIR Inheritance flags are only allowed for ACLs on directories.
