6Tb Database with ZFS
Hello,
Im about to migrate a 6Tb database from Veritas Volume Manager to ZFS, I
want to set arc_max parameter so ZFS cant use all my system''s memory, but i
dont know how much i should set, do you think 24Gb will be enough for a 6Tb
database? obviously the more the better but i cant set too much memory.
Have someone implemented succesfully something similar?
We ran some test and the

Properties list for zfs in FreeBSD
Hi:
Where can I find a list of properties (-o/-O property=value) for
creating a zpool?
I meant something like:

-o ashift=12 \
-0 dedup=off
-O autoexpand=off
-O atime=off \
-O canmount=off \
-O compression=lz4 \

Upgrading from FreeBSD10-B3 to FreeBSD10-RC1 borked
Followed the instructions here:
http://www.freebsd.org/doc/handbook/updating-upgrading-freebsdupdate.html
The upgrade borked.
Error message: Can't find 'kernel'
When I checked with ls /boot/kernel/, the directory does exist.

Since the system has encrypted root partion with ZFSonROOT, I tried to

How do I clean up corrupted files from zpool status -v?
Hi Folks..
I have a system that was inadvertently left unmirrored for root. We were able
to add a mirror disk, resilver, and fix the corrupted files (nothing very
interesting was corrupt, whew), but zpool status -v still shows errors..
Will this self correct when we replace the degraded disk and resilver? Or is
there something else that I''m not finding that I need to do to clean up?

simulating directio on zfs?
I had to let this go and get on with testing DB2 on Solaris. I had to
abandon zfs on local discs in x64 Solaris 10 5/08.
The situation was that:
* DB2 buffer pools occupied up to 90% of 32GB RAM on each host
* DB2 cached the entire database in its buffer pools
o having the file system repeat this was not helpful
* running high-load DB2 tests for 2 weeks showed 100%

current zfs tuning in RELENG_7 (AMD64) suggestions ?
I gave the AMD64 version of 7.2 RC2 a spin and all installed as
expected off the dvd
INTEL S3200SHV MB, Core2Duo, 4G of RAM
In the past it had been suggested that for zfs tuning, something like
vm.kmem_size_max="1073741824"
vm.kmem_size="1073741824"
vfs.zfs.prefetch_disable=1
However doing a simple test with bonnie and dd, there does not seem
to be very much difference in

ZFS ARC & DNLC Limitation
Hello All,
Awhile back (Feb ''07) when we noticed ZFS was hogging all the memory
on the system, y''all were kind enough to help us use the arc_max
tunable to attempt to limit that usage to a hard value. Unfortunately,
at the time a sticky problem was that the hard limit did not include
DNLC entries generated by ZFS.
I''ve been watching the list since then and trying to

Problems booting into ZFS on recent stable/9
I had a sparc64 (Netra X1) running a stable/9 from late March 2013. Actually, the kernel may've been a bit newer than that as I was working with folks to diagnose and repair some Netra-X1 specific issues. But, ZFS worked fine. I have two pools, zroot as a RAID1 (using equally sized partitions at the front of two large disks), and a zdata that is a large pool of the remaining space of both

FreeBSD 10 Beta 2: make installkernel failure with installer provided ZFS configuration.
Hi,
I was trying to rebuild world on a FreeBSD 10 test system, that I had just
installed. ZFS root was setup. I let the installation program do all the
ZFS setup and configuration. I put root on a 5 disk encrypted raidz array.
Besides the installer configuring 5 times the amount of swap space I asked
for (asked for 8gb, installer put 8gb on each drive, for 40gb in total.)

FreeBSD 9.1 - openldap slapd lockups, mutex problems
Hi.
(Im am sending this to the "stable" list, because it maybe kernel related.. )
On 9.1-RELEASE I am witnessing lockups of the openldap slapd daemon.
The slapd runs for some days and then hangs, consuming high amounts of CPU.
In this state slapd can only be restarted by SIGKILL.

recommended setup for amd64 7-STABLE with ZFS, Samba 3.2 and possibly ACLs?
Hi,
could anyone give recommendations (or share experience) regarding
using ZFS:
- FreeBSD 7-Stable (amd64 with 8GB RAM)
+ special tuning necessary (apart from increasing kernel memory
to 1 or more GB for ZFS)
- Samba 3.2
+ ACLs possible directly under ZFS?
+ recommended compile options?
- NFS
- email (imap)
- jails (I have seen some problems exist with using snaphots within
