I installed your Lychee docker today and I get the webUI configuration screen. However, I get failures when attempting to create the database from the initial UI screen 'unable to create database - access denied'. I only filled out username and password as the other options say 'optional'. I also made sure data and uploads were set to 777 and everything in /data is nobody users. Any tricks to get this working?

Just reporting this issue, have not seen it before. I am going to move my image to another ssd (xfs) outside of the array anyway. Brought up the system on beta14, deleted my current docker.img using the new 'delete image' feature in the gui (on a brrfs pool - cache drive). I then attempted to recreate it from the gui and it just hangs on the docker screen. I checked syslog and saw this: Feb 21 14:30:58 Iron php: Creating new image file for Docker: /mnt/cache/docker/docker.img size: 32G Feb 21 14:30:59 Iron php: Btrfs v3.18.2#012See http://btrfs.wiki.kernel.org for more information.#012#012Turning ON incompat feature 'extref': increased hardlink limit per file to 65536#012Turning ON incompat feature 'skinny-metadata': reduced-size metadata extent refs#012fs created label (null) on /mnt/cache/docker/docker.img#012#011nodesize 16384 leafsize 16384 sectorsize 4096 size 32.00GiB Feb 21 14:30:59 Iron kernel: BTRFS: device fsid 4cff6c9a-f60b-4ea8-8507-8c21376ef7b5 devid 1 transid 4 /dev/loop2 Feb 21 14:30:59 Iron kernel: BTRFS info (device loop2): disk space caching is enabled Feb 21 14:30:59 Iron kernel: BTRFS: has skinny extents Feb 21 14:30:59 Iron kernel: BTRFS: flagging fs with big metadata feature Feb 21 14:30:59 Iron kernel: BTRFS: creating UUID tree Feb 21 14:30:59 Iron php: Resize '/var/lib/docker' of 'max' Feb 21 14:30:59 Iron php: starting docker ...

I am going to remove it and try again on an XFS SSD outside of the array.

Thanks for the info! I was able to do the same thing!

This should work even though I am using a cache pool?

I believe I used the instructions here: Command Line Method Lime Technology - unRAID Server Community » Company » Announcements » unRAID 6 Beta 6: Btrfs Quick-Start Guide http://lime-technology.com/forum/index.php?topic=33806.0

I only rebooted once after the install asked for the reboot. I have attatched my syslog for your review. Thanks in advance! syslog.txt

I updated to beta13 today through the webgui. After the reboot, my cache drive pool is also showing unformated. I assume I have lost the syslog since I rebooted (as instructed by the webgui after the update). From reading this thread, it sounds like this is being addressed in beta14. Since that is not available, is there a working method to go back to beta13 or to extract my data from the pool and reformat?

I love this addon, really great work. Is there a way to include additonal arguments to the docker call? I wanted to experiment with linking docker containers as described below using the --link argument. Is there a way to do this currently using a template? Or a manual method? Ideas?...

Upgraded from 10a to 12. All working as expected so far. Love the dynamix integration.

That step took some time on my system too, so just be patient. Thanks BRit, beer it is.....

I installed from the extensions page, but it is still sitting at: syncing... Has been stuck there for a while, should I be concerned or just crack a beer and wait it out? I am preclearing two WD Red 3TB drives as well, perhaps not the best time to do an upgrade....

The command you used would be ok if that was your 'cache' device, but if that was an array device, resizing the partition like that invalidates parity. For that reason, I edited your post and deleted those lines because I don't want anyone else to do that. I'll post correct instructions later... Sounds good, thanks for the update. I will watch for the correct instructions later. Meanwhile...I will start a parity rebuild... Parity check should be fine. If the replacement disk was precleared you should not see many parity errors. If not you'd see a bunch. But either way the parity check will correct then (if you run a correcting check) and be faster than a build. Thanks for the info, I will give it a shot.

Code used to just do an unconditional "resize" upon every mount, and that was not an issue because with reiserfs it just was a no-op. But with btrfs/xfs there needs to be a little more sophistication in the coding. I didn't want to delay beta7 another week to get this in, so left auto-resize out until next release. If someone needs to do an expansion before beta8 I will post instructions. Yes. Can you post the instructions for 'If someone needs to do an expansion before beta8 I will post instructions.'? [Edited to delete lines that can cause invalid parity - limetech]

We haven't seen any IO performance issues yet with btrfs and image files for KVM but let us know if upon further testing you find some. So, I shut down the windows81pro kvm (on the btrfs cache drive) copied the files to a ReiserFS drive outside of the array. I adjusted the pathing in the kvm xml configuration file and booted up the vm. CrystalDiskMark 3.0.3 Shizuku Edition x64 reports: BTRFS Filesystem sectorsize 4096, nodesize 16384, leafsize 16384) Seq Read: 710 [MB/s] Seq Write: 5.5 [MB/s] ReiserFS V3.6 Seq Read: 2027 [MB/s] Seq Write: 46.8 [MB/s] Obviously more testing is needed as this could be 100% an issue with my environment, but it is certanly a huge difference in this case. Food for thought....

I was getting poor performance on disk writes so I started looking for information about improving write speed in KVM and Win 8.1. I did find this interesting blurb at http://www.linux-kvm.org/page/Tuning_KVM Storage QEMU supports a wide variety for storage formats and back-ends. Easiest to use are the raw and qcow2 formats, but for the best performance it is best to use a raw partition. You can create either a logical volume or a partition and assign it to the guest: qemu -drive file=/dev/mapper/ImagesVolumeGroup-Guest1,cache=none,if=virtio QEMU also supports a wide variety of caching modes. If you're using raw volumes or partitions, it is best to avoid the cache completely, which reduces data copies and bus traffic: qemu -drive file=/dev/mapper/ImagesVolumeGroup-Guest1,cache=none,if=virtio As with networking, QEMU supports several storage interfaces. The default, IDE, is highly supported by guests but may be slow, especially with disk arrays. If your guest supports it, use the virtio interface: qemu -drive file=/dev/mapper/ImagesVolumeGroup-Guest1,cache=none,if=virtio Don't use the linux filesystem btrfs on the host for the image files. It will result in low IO performance. The kvm guest may even freeze when high IO traffic is done on the guest. I did a quick search here and did not see this mentioned, so I just wanted to put it out there. I am going to move my KVM Windows 8.1 vm off of the btrfs cache drive and see what happens.

Done - Works like a charm now, thanks for looking at this!

I have been playing with this headphones container.
