Re: [zfs-macos] RAIDZ1 running slow =(
Hi guys! What a journey. So with school and work I finally was able to get everything pulled off my ZFS pool and ready to rebuild it. Except I can't find the developer version... I'm at downloads.maczfs.org and checked current and all downloads and the last release seems to be MacZFS-74.3.3.pkg, which I have installed: collect-maczfs-state.sh v maczfs_74-3-3-68-ga26cd63 Determining system version # uname -a Darwin Jamess-iMac.local 13.2.0 Darwin Kernel Version 13.2.0: Thu Apr 17 23:03:13 PDT 2014; root:xnu-2422.100.13~1/RELEASE_X86_64 x86_64 Looking for ZFS packages # -v pkgs -sl Found %d packages pkgutil --pkgs | grep -e zfs -e ZFS -e ZEVO -e zevo com.getgreenbytes.community.zfs.pkg com.getgreenbytes.community.ZFSDriver.pkg com.getgreenbytes.community.ZFSFilesystem.pkg org.maczfs.zfs.106.pkg Found 4 packages So where is the developer version? Everything else is marked as depreciated. Please help D: I want to use the latest build experimental or not. I'm going to use this line once I get the new version installed: zpool create -f -O compression=lz4 -O casesensitivity=insensitive -O normalization=formD -O atime=off -o ashift=12 deathstar raidz disk1 disk2 disk3 disk5 Do I need to delete the pool first or format the drives in any way special before doing this?

As said in my other mail an hour ago, normalization doesn't exist in the stable MacZFS version. Also each option needs its own -o and ashift is a pool option, not a file system option. You do zpool create -o ashift=12 -O atime=off murr _devices_ ... Note the capital -O and the small letter -o. And for subsequent file systems (datasets in ZFS language) you use zfs create -o atime=off _pool_name/fs_name_ If you used the development version, then you would add a -O normalization=formD in the zpool command and a -o normalization=formD in the zfs command. Best regards Björn As for the slowness in a VM, Mac file sharing would affect it because Windows 8 accesses the drives with Fusion by mounting \\jamess-imac\Volumes\murr as the Z drive so it technically is a file share if that's what you mean. But it could also be because the slowness of not using a 4k compatible zpool is compounded with a virtual machine. (Could someone updated the getting started guide to have you create a 4k zpool by default?) Thanks for the advice on Songbird! I may try it if it can organize via masks and support custom ID3 fields. I saw it's discontinued though but it's still on SourceForge. I'm at work so can't give a better reply but I have a lot more to look into and read now =) - James On Tue, May 20, 2014 at 2:07 PM, 'Busty' via zfs-macos zfs-macos@googlegroups.com wrote: James, I use my 15TB pool mainly for flac files too, so I thought I'd throw in my two cents (even if some is not zfs related): regarding iTunes recognizing flac: There is a quicktime component that will enable flac in quicktime, iirc it also works in itunes, at least you can get it too. But it will not play gapless, there is an amount of silence between songs. Another thing is called TwistedFlac, which in a folder you can specify shows all flac files as wave files. These can be imported into iTunes, the downside is that the tags are not recognized. Just in case that helps with your library. I use songbird, which can about anything you want, but is not as stable as iTunes. Regarding your files showing up very slow, I experience that when I access my files on the pool from a remote machine which has to do with AFP (Apple filesharing protocol), so I have set up a NFS share. But you don'T writ eabout accessing the files from a a remote machine, so this should not be your issue. I kinda went the way you did. I had no knowledge of zfs but really wanted the features for data safety. That was roughly 3-4 years ago. As I set up my pool (and my backup, by the way), I came across all kinds of problems (drives vanishing, kernel panics, slow file browsing, scripts to automate backups and scrubs, you name it) which had to be solved, so I had a lot of reading and googling to do. I kinda was fooled by the MacZFS tutorial into thinking that this will be completely easy like you describe. These guys, in the front row Jason and Alex Blewitt and Bjoern helped me a lot to get on the way (so thanks again guys) Sebastian On 20.05.14 20:28, James Hoyt wrote: Hi Bjorn

Re: [zfs-macos] RAIDZ1 running slow =(
the folders show, but they do in the Finder. So I wonder if this is an issue with programs not getting along with ZFS but the finder being fine with it. Other things to note, I did disable Spotlight on the drive to make sure that isn't running, but I do have QuickSilver. Originally, I had QuickSilver indexing the drive, but the computer was practically unusable when it did that so I disabled that. I look forward to any advice you guys may have.

I’ve seen precisely this sort of behaviour with vmware fusion
when:
1. my SSD was getting worn down (really, I trashed it in 1 year,
it was the default apple one coming with early 2011 MBP)
2. the host OS VM doesn’t have sufficient memory to run
correctly without swapping
3. the additional memory within the VM is pulled from a disk swap
file, which is by default in the same disk location as the VM itself
Anything less than 8GB of RAM is likely to be tight, VMs will of
course make this more complicated. Some notes on
http://artykul8.com/2012/06/vmware-performance-enhancing/ may help.
I found that my SSDs were being worn out with constant running of
VMs; I use them heavily in my work. The solution I found was to get max RAM
in my laptop + imac (16 vs 32 respectively), make a zfs based ramdisk with
lz4 compression, and copy the entire VM into the ramdisk before running it.
The copy phase only takes a few seconds from SSD, and it gives me a very
nice way to “roll back” to the previous image when required. I can
comfortably run Windows in a 20GiB ramdisk that fits inside a 10GiB zpool
with compression, even on the 16GiB laptop, and allocating 2GiB of ram for
the VM itself (10 + 2 for virtualisation leave 4 for all of OSX stuff).
Here’s the zsh functions I use for this.
# create a 1GiB ramdisk
ramdisk-1g () {
ramdisk-create 2097152
}
# the generic function for the specific one above
ramdisk-create () {
diskutil eject /Volumes/ramdisk /dev/null 21
diskutil erasevolume HFS+ 'ramdisk' `hdiutil attach -nomount
ram://$1`
cd /ramdisk
}
# make a zpool backed ramdisk instead of the HFS+ ones above.
Main advantage is compression. I get at least 2x more “disk” for RAM with
this approach.
zdisk () {
sudo zpool create -O compression=lz4 -fm /zram zram `hdiutil
attach -nomount ram://20971520`
sudo chown -R $USER /zram
cd /zram
}
# self explanatory
zdisk-destroy () {
sudo zpool export -f zram
}

Re: [zfs-macos] RAIDZ1 running slow =(
it will take 1-3 minutes to just list the files in the directory). Also when I'm saving images from Firefox (no virtual machine running) it takes awhile to navigate the folder structure and sometimes not all the folders show, but they do in the Finder. So I wonder if this is an issue with programs not getting along with ZFS but the finder being fine with it. Other things to note, I did disable Spotlight on the drive to make sure that isn't running, but I do have QuickSilver. Originally, I had QuickSilver indexing the drive, but the computer was practically unusable when it did that so I disabled that. I look forward to any advice you guys may have.

I’ve seen precisely this sort of behaviour with vmware fusion
when:
1. my SSD was getting worn down (really, I trashed it in 1 year,
it was the default apple one coming with early 2011 MBP)
2. the host OS VM doesn’t have sufficient memory to run
correctly without swapping
3. the additional memory within the VM is pulled from a disk swap
file, which is by default in the same disk location as the VM
itself
Anything less than 8GB of RAM is likely to be tight, VMs will of
course make this more complicated. Some notes on
http://artykul8.com/2012/06/vmware-performance-enhancing/ may help.
I found that my SSDs were being worn out with constant running of
VMs; I use them heavily in my work. The solution I found was to
get max RAM
in my laptop + imac (16 vs 32 respectively), make a zfs based
ramdisk with
lz4 compression, and copy the entire VM into the ramdisk before
running it.
The copy phase only takes a few seconds from SSD, and it gives me
a very
nice way to “roll back” to the previous image when required. I can
comfortably run Windows in a 20GiB ramdisk that fits inside a
10GiB zpool
with compression, even on the 16GiB laptop, and allocating 2GiB of
ram for
the VM itself (10 + 2 for virtualisation leave 4 for all of OSX
stuff).
Here’s the zsh functions I use for this.
# create a 1GiB ramdisk
ramdisk-1g () {
ramdisk-create 2097152
}
# the generic function for the specific one above
ramdisk-create () {
diskutil eject /Volumes/ramdisk /dev/null 21
diskutil erasevolume HFS+ 'ramdisk' `hdiutil attach -nomount
ram://$1`
cd /ramdisk
}
# make a zpool backed ramdisk instead of the HFS+ ones above.
Main advantage is compression. I get at least 2x more “disk” for
RAM with
this approach.
zdisk () {
sudo zpool create -O compression=lz4 -fm /zram zram `hdiutil
attach -nomount ram://20971520`
sudo chown -R $USER /zram
cd /zram
}
# self explanatory
zdisk-destroy () {
sudo zpool export -f zram
}
