Reconstruct disklabel for UFS and GELI volumes
Hi,
Somehow[TM] an installation of 4.11 to ad0s3 managed to wipe out my
existing disklabel for 7.0 on ad0s4. I now need to recover the
disklabel to get my system to boot!
There were three labels
- ad0s4a: UFS, exact size unknown. Is it possible to infer this from
the UFS partition size? I can mount this already, as I simply wrote an
'a' label of maximum size to the disklabel
- ad0s4b:

Hi All,
With the help of Chuck Tuffli, I'm now able to use CTL to export a zvol over FC to a Linux host:

Bad SWAP performance from zvol
I''ve upgraded my system from ufs to zfs (root pool).
By default, it creates a zvol for dump and swap.
It''s a 4GB Ultra-45 and every late night/morning I run a job which takes
around 2GB of memory.
With a zvol swap, the system becomes unusable and the Sun Ray client often
goes into "26B".
So I removed the zvol swap and now I have a standard swap partition.

How create a FAT filesystem on a zvol?
The `lofiadm'' man page describes how to export a file as a block
device and then use `mkfs -F pcfs'' to create a FAT filesystem on it.
Can''t I do the same thing by first creating a zvol and then creating
a FAT filesystem on it? Nothing I''ve tried seems to work. Isn''t the
zvol just another block device?

GELI partition mount on boot fails after 7.0 -> 7.1-PRERELEASE upgrade
I was using a GELI partition for /usr/home on 7.0, so it attaches and mounts
on boot. The problem is it stopped working after the system was upgraded to
RELENG_7/7.1-PRERELEASE. Here's how it goes:
I have the following /etc/fstab:
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1

safe zfs-level snapshots with a UFS-on-ZVOL filesystem?
I had some trouble installing a zone on ZFS with S10u4
(bug in the postgres packages) that went away when I used a
ZVOL-backed UFS filesystem
for the zonepath.
I thought I''d push on with the experiment (in the hope Live Upgrade
would be able to upgrade such a zone).
It''s a bit unwieldy, but everything worked reasonably well -
performance isn''t much worse than straight

UFS on zvol: volblocksize and maxcontig
Hi all!
First off, if this has been discussed, please point me in that
direction. I have searched high and low and really can''t find much info
on the subject.
We have a large-ish (200gb) UFS file system on a Sun Enterprise 250 that
is being shared with samba (lots of files, mostly random IO). OS is
Solaris 10u3. Disk set is 7x36gb 10k scsi, 4 internal 3 external.

Getting GELI Keys from Floppy
Hello,
i want to encrypt my HDD's with GELI (not the root-fs, though). I want
to do the encryption without password, just with a key. The key should
be stored in a floppy disk, and the read should be read automatically
on boot, from the floppy.
There is a problem here, because GELI initializes _before_ mounting
the disks from /etc/fstab (for obvious reasons, of course). So GELI is

ZVOL access permissions?
How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes).
Thanks,

zfs send of a cloned zvol
Hi,
I have a question, let''s say I have a zvol named vol1 which is a clone of a snapshot of another zvol (its origin property is tank/myvol at mysnap).
If I send this zvol to a different zpool through a zfs send does it send the origin too that is, does an automatic promotion happen or do I end up whith a broken zvol?
Best regards.
Maurilio.

Making a zvol unavailable to iSCSI trips up ZFS
I''ve been experimenting with a two system setup in snv_134 where each
system exports a zvol via COMSTAR iSCSI. One system imports both its
own zvol and the one from the other system and puts them together in
a ZFS mirror.
I manually faulted the zvol on one system by physically removing some
drives. What I expect to happen is that ZFS will fault the zvol pool
and the iSCSI stack will

geli or gbde encryption of slices
Hello,
I was playing around with geli an gbde after last EuroBSDCon.
I liked the idea of encrypting my data which resides in /home/$user.
Since this is a "single" user laptop i intended to encrypt the
whole /home partition. Well no problems with that. But i wanted
the lockfile or keyfile on a seperate usb disc. Which would be
mounted or used during boot of the system. I also used

zvol wrapped in a vmdk by Virtual Box and double writes?
Hi folks, (Long time no post...)
Only starting to get into this one, so apologies if I''m light on detail,
but...
I have a shiny SSD I''m using to help make some VirtualBox stuff I''m
doing go fast.
I have a 240GB Intel 520 series jobbie. Nice.
I chopped into a few slices - p0 (partition table), p1 128GB, p2 60gb.
As part of my work, I have used it both as a RAW

system unresponsive after issuing a zpool attach
Today I attempted to upgrade to S10_U2 and migrate some mirrored UFS SVM
partitions to ZFS.
I used Live Upgrade to migrate from U1 to U2 and that went without a
hitch on my SunBlade 2000. And the initial conversion of one side of the
UFS mirrors to a ZFS pool and subsequent data migration went fine.
However, when I attempted to attach the second side mirrors as a mirror
of the ZFS pool, all

Encrypted volume - how?
Hi all,
I'm looking for a way to recreate the functionality of PGP Disk (under
Win32). Basically, create an encrypted file, which contains a filesystem
which can then be mounted in any mount point.
I know I can use GELI in FreeBSD 6 - as I understand, it performs the
encryption at the partition level (the whole partition is encrypted).
I'd like to be able to simply unmount my

zfs drive keeps failing between export and import
I have a zpool that consists for a two-drive mirror. The two times I
took the zpool offline, I had to resilver one of the drives (the same
drive both times) when I imported it back. All drives in the pool
show no read, write, or checksum errors and are new, so I'm looking to
a software problem before hardware. Both drives are encrypted geli
devices. I tried to reproduce the error with 1GB

kern/157863: [geli] kbdmux prevents geli passwords from being entered properly on boot

Just to let everyone know that this is still an issue.
I am trying to install FreeBSD 9.0 amd64 on a Lenovo X121e and I
can't get it to accept the geli passphrase during boot. I've confirmed
using kern.geom.eli.visible_passphrase=1 that the passphrase is
correct, and the same passphrase is accepted when the system is

zfs: zvols minor #''s changing and causing probs w/ volumes
Team,

QUICK PROBLEM DESCRIPTION:
Cu created a dataset which contains all the zvols for a particular

using a match statement in the zoneconfig (see long problem description
for details). After the initial boot of the zone
