erocm123 Posted August 21, 2014 Share #1 Posted August 21, 2014 Warning: This seems to be working well, but is in it's very early stages. Play with it at your own risk. So I have gotten zfs compiled and working on nanoboot 5.0.3.1 with DSM 5.0-4493. It wasn't pretty getting it going, but it seems like the functionality that I want is there. Compression, snapshots, clones, replication, etc. I haven't had too much time to mess with it but performance seems pretty good. I am a Linux Admin, but I mostly work with Redhat / CentOS and this is actually the first time that I have cross-compiled. In that sense I am a newb so there are probably much better ways to do what I have done. If so, please let me know. I've compiled from source in the past, but this was a little different. I'm so used to YUM or other package managers . . . Anyway, there is one small hurdle that I am trying to overcome. It seems that the Synology implementation of Samba does something a little tricky that the Kernel / ZFS don't like. Perhaps it is related to ACLs. When I initiate a copy from Windows, Windows believes there is no room on the volume and in dmesg I see: [ 1534.802643] write_begin() or write_end() is not implemented When I use the samba2 package from ipkg the Samba shares work just fine. If you want to give it a shot, here are the files and instructions. As I haven't tested much, I don't recommend using in production: Unpack and load the kernel modules (change the commands to where you have unpacked the modules): insmod /opt/lib/modules/3.2.40/spl.ko insmod /opt/lib/modules/3.2.40/splat.ko insmod /opt/lib/modules/3.2.40/zavl.ko insmod /opt/lib/modules/3.2.40/znvpair.ko insmod /opt/lib/modules/3.2.40/zunicode.ko insmod /opt/lib/modules/3.2.40/zcommon.ko insmod /opt/lib/modules/3.2.40/zfs.ko insmod /opt/lib/modules/3.2.40/zpios.ko Library files need to go into /lib64/ DSM5> tar -zxf libuuid.so.1.3.0.tar.gz DSM5> chmod 755 libuuid.so.1.3.0; cp libuuid.so.1.3.0 /lib64/; rm /lib64/libuuid.so; rm /lib64/libuuid.so.1; ln -s /lib64/libuuid.so.1.3.0 /lib64/libuuid. so; ln -s /lib64/libuuid.so.1.3.0 /lib64/libuuid.so.1 DSM5> tar -zxf libz.so.1.2.8-x64.tar.gz DSM5> cp -p libz.so.1.2.8 /lib64/; ln -s /lib64/libz.so.1.2.8 /lib64/libz.so; ln -s /lib64/libz.so.1.2.8 /lib64/libz.so.1 Install the deb packages with dpkg. I was lazy and sick of messing around with things so I just did a: DSM5> dpkg -i --force-all *.deb Since I didn't have udevadm I had to create the zfs device pointer manually: DSM5> cat /sys/class/misc/zfs/dev 10:57 DSM5> mknod /dev/zfs c 10 57 At this point zfs and zpool commands should work. zpool create tank /dev/sdXX <---- change this to the device you want to use. Create dataset zfs create tank/data Turn on compression: zfs set compression=on tank/data These should mount automatically, but you can change the mount type to "legacy" and mount them with fstab or manually. zfs set mountpoint=legacy tank/data mount -t zfs -o usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,synoacl,defaults,atime,dev,exec,rw,suid,xattr,nomand,zfsutil,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,synoacl tank/data /volume1/zfs/data Take a snapshot zfs snapshot tank/data@snapshot0821 I'm out of time for now. Will post more later. Link: https://drive.google.com/file/d/0B_7bVXd64Md1Q054Qy1FWVd4bEU/edit?usp=sharing Link to comment Share on other sites More sharing options...
kei78 Posted August 21, 2014 Share #2 Posted August 21, 2014 wow...interesting...good stuff even getting this to partially work! What type of system specs are you running...I ask as some of the functions are pretty cpu/memory intensive which is why freenas has higher system requirements to run as compared to synology.

erocm123 Posted August 21, 2014 Author Share #3 Posted August 21, 2014 I currently have it running as an ESXi VM on top of a Gen 8 HP Microserver. The Microserver has been modified to have a Intel Xeon CPU E3-1230 V2 3.30GHz. I've given the VM 4GB of RAM and 4 CPU Cores. I have FreeNAS running alongside this on the same hardware with the same specs (4GB RAM 4 CPU cores) and performance has been really good with it. I'll have to see how the SynologyZFS setup compares. I don't use dedupe in my home lab as it requires more resources, but I do use compression. I've used dedupe out in the workforce but it has been on multi controller SANS with lots of RAM.

In0cenT Posted August 21, 2014 Share #4 Posted August 21, 2014 Well if ZFS and Xpenology work well, this will be very interesting! Sadly I havent got any skills to support your genius work! Link to comment Share on other sites More sharing options...
Nindustries Posted August 21, 2014 Share #5 Posted August 21, 2014 Imagine XPenology evolving into a ZFS-equivalent of DSM...and then getting bought out/implemented by Synology Seriously, good work. We knew eventually someone was going to buckle up and try this out. Edit: Mirrored your files just to be sure. http://mir.cr/1ECPZWO5 Link to comment Share on other sites More sharing options...
erocm123 Posted August 21, 2014 Author Share #6 Posted August 21, 2014 Thanks for the mirror. I am still trying to figure out Samba. NFS works fine, but I am still having problems with the Synology compiled Samba. Not sure what is going on. As mentioned before, the Samba package that is available via ipkg is working great.

erocm123 Posted August 21, 2014 Author Share #7 Posted August 21, 2014 By the way, here is the init script that I use to automatically load the kernel modules. I borrowed it and modified it from somewhere else: I've got ipkg / bootstrap setup so I put the init script in /opt/etc/init.d/S10modules #!/bin/sh # Original script has been written by Davy Leggieri (hey another French guy # Modified by Charles-Henri Hallard on April 2012 to fit with my configuration # # there is start stop var because at stop modules usbserial should be unloaded last MODULES_DIR="/opt/lib/modules/3.2.40" MODULES_START="spl.ko splat.ko zavl.ko znvpair.ko zunicode.ko zcommon.ko zfs.ko zpios.ko" MODULES_STOP="zpios.ko zfs.ko zcommon.ko zunicode.ko znvpair.ko zavl.ko splat.ko spl.ko" start_modules(){ echo "--- Load modules ---" for i in $MODULES_START; do echo "Loading $i" insmod $MODULES_DIR/$i done } stop_modules(){ echo "--- Unload modules ---" for i in $MODULES_STOP; do echo "Unloading $i" rmmod $MODULES_DIR/$i done } case "$1" in start) start_modules ;; stop) stop_modules ;; *) echo "usage: $0 { start | stop }" >&2 exit 1 ;; Link to comment Share on other sites More sharing options...
erocm123 Posted August 23, 2014 Author Share #8 Posted August 23, 2014 Seems like Synology has included a few vfs hooks in their version of Samba. I believe it is one of them that is causing problems: synosmb_vfs_acl_init synosmb_vfs_indexing_init synosmb_vfs_stream_init synosmb_vfs_xattr_init synosmb_vfs_xferlog_init Troubleshooting their samba modules is a little over my head right now. I've compiled smbd from source (without the modules) and it seems to work fine with the zfs mounts that I have. No indication of any problems from the GUI and shares work how I expect. I have never really gotten into Windows ACLs on Synology so I'm not sure if they are behaving properly. Link to comment Share on other sites More sharing options...

Schnapps Posted August 30, 2014 Share #10 Posted August 30, 2014 Good work mate but I'm a techie and coming from FreeNAS and OVM 2y ago and I never had missed the ZFS. I consider having ZFS on XPEnology is just for geeks. No real advantages and major resources hog. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
